Combination gun

A combination gun is a versatile multi-barrel firearm that incorporates at least one rifled barrel for firing bullets and one smoothbore barrel for discharging shot or slugs, enabling hunters to address diverse game types with a single weapon.^[1] These firearms originated in Europe during the late 19th century, driven by the demand for adaptable hunting tools amid overlapping seasons for birds and big game.^[1] In Germany, the drilling configuration emerged around 1900 as a three-barrel design—typically two 12- or 16-gauge shotgun barrels over a central rifle barrel in calibers like .30-30 Winchester or 6.5x57R—prized by foresters for its balance of weight (6 to 9 pounds) and utility.^[2]^[1] Combination guns are produced in various layouts, including over/under arrangements for compact handling, side-by-side Cape guns for quicker barrel selection, and rarer vierlings with four barrels for extreme versatility.^[1] Key features often include selective triggers or safety mechanisms to switch between barrels, free-floating construction for accuracy, and manual cocking systems, as seen in modern models from manufacturers like Blaser (e.g., the single-lock BBF 95 series) and Sauer & Sohn.^[3] In the United States, the Savage Model 24 over/under (.22 Hornet/.410 bore), introduced in 1950 and discontinued in 2010, exemplified affordable accessibility, originally priced at about $70.^[1] Primarily employed for civilian hunting in regions with varied terrain and game—such as European woodlands or American plains—these guns enhance safety and efficiency by reducing the need to carry multiple firearms, though they must comply with local regulations on multi-caliber use.^[3]^[1] Military adaptations, like the WWII-era German M30 Luftwaffe Drilling for aircrew survival, highlight their broader historical role in compact, dual-purpose armament.^[2]

History

Origins

The earliest combination guns appeared in Europe during the 16th to 18th centuries, primarily as swivel breech designs that allowed hunters to switch between rifled and smoothbore barrels without fully disassembling the firearm. These rudimentary firearms originated in Germanic regions, where gunsmiths developed mechanisms to address the challenges of muzzleloading in the black powder era. By the mid-17th century, swivel breeches—known as "wenders" in German, meaning "turners"—enabled the rotation of multiple barrels into position for firing, providing a practical solution for multi-purpose hunting weapons.^[4]^[5] These early designs typically featured separate flintlock mechanisms, one for each barrel type, to ensure reliable ignition despite the differing loads: a rifled barrel for precision shots at larger game and a smoothbore barrel for scattering shot at birds or smaller quarry. The swivel action facilitated quicker reloading compared to fixed-barrel alternatives, as the breech could pivot to expose the chambers for powder and projectile insertion. This configuration was particularly suited to the limitations of black powder firearms, where fouling from residue and the time-intensive process of muzzleloading demanded tools that minimized downtime in the field.^[6]^[7] A notable example is the 18th-century German jagdflints, or hunting flintlocks, produced in centers like Ulm, which incorporated swiveling barrels for efficient loading during hunts. One such surviving piece, crafted by J. Ernst Fiedler around 1760, pairs an octagonal rifled barrel with seven-groove rifling alongside a part-octagon, part-round smoothbore barrel, both inlaid with the maker's mark and demonstrating the era's fine craftsmanship. These guns reflected the practical needs of European hunters in forested regions teeming with diverse game, from deer and boar to fowl, where a single weapon had to adapt to varying opportunities without the luxury of multiple specialized arms.^[6] The first documented swivel breech combination guns date to the 1600s in Germanic areas, marking the inception of this versatile firearm type amid the slow evolution of ignition systems from wheellock to flintlock. This early innovation laid the foundation for subsequent refinements in action designs.^[4]

Development and Popularization

The introduction of self-contained metallic cartridges in the 1860s marked a pivotal advancement in firearm technology, facilitating the development of break-action designs that integrated multiple barrel types into compact, reloadable configurations ideal for combination guns.^[8] This shift from muzzle-loading systems to breech-loading mechanisms allowed for quicker reloading and greater versatility, enabling hunters to pair rifled barrels for precision shots with smoothbore barrels for scatter loads. Austrian gunmakers, including the Fanzoj family in Ferlach, contributed significantly to this evolution, building on their centuries-old tradition of craftsmanship to refine break-action combination firearms during the late 19th century.^[9] Combination guns saw widespread popularization in Europe, particularly in Germany and Austria, where they became essential tools for foresters and hunters navigating varied game in dense woodlands.^[10] In the colonial eras of the late 19th and early 20th centuries, these firearms gained traction in Africa among big game hunters, prized for their adaptability in pursuing everything from birds to dangerous animals like elephants and lions without needing multiple weapons.^[11] The rise in production accelerated after the 1870s with the advent of nitrocellulose smokeless powder in 1884, which produced less residue, higher velocities, and safer operation in multi-barrel setups, transforming combination guns from niche prototypes to standard hunting arms.^[12] Notable examples include the early drillings from J.P. Sauer & Sohn, with the firm's first three-barrel models emerging around 1881 and gaining prominence by 1890 for their robust construction and selective firing systems.^[13] By 1900, the regional spread extended to the Middle East and Asia, where European colonial influences and trade introduced combination guns for versatile field use in rugged terrains and mixed-game environments.^[14]

Design and Construction

Barrel Configurations

Combination guns feature a variety of barrel configurations to accommodate both rifled and smoothbore barrels, allowing versatility in hunting scenarios. The most common arrangements include over-and-under and side-by-side layouts, each offering distinct structural advantages. In the over-and-under configuration, one barrel is stacked vertically atop the other, typically with a smoothbore shotgun barrel (such as 12-gauge) on top and a rifled barrel (such as .22LR) below, resulting in a thinner profile that aids in handling and sighting along a continuous rib.^[15]^[16] This setup provides balanced weight distribution, making it suitable for prolonged field carry.^[17] In contrast, the side-by-side configuration positions the barrels horizontally parallel to each other, often seen in cape guns where a smoothbore shotgun barrel adjoins a rifled one. This layout facilitates quicker target acquisition due to the broader horizontal alignment, which aligns naturally with a shooter's instinctive swing across a wider field of view.^[14]^[18] Multi-barrel setups extend these principles to more complex arrangements. A drilling typically consists of three barrels: two side-by-side smoothbore shotgun barrels positioned over a central rifled barrel, enabling rapid switching between shot and bullet for mixed game.^[2]^[19]^[20] The vierling, a four-barrel variant, commonly features a square arrangement or paired over-and-under sets, such as two smoothbore barrels alongside two rifled ones of differing calibers (e.g., one rimfire and one centerfire), optimized for driven hunts requiring sequential firing.^[14]^[21]^[22] Historically, combination gun barrels were often constructed from Damascus steel, a pattern-welded material forged from layered iron and steel rods for aesthetic appeal and sufficient strength under black powder loads.^[23]^[24] However, modern iterations employ chrome-molybdenum alloys, such as 4140 or 4150 steel, which offer superior durability, ductility, and resistance to high-pressure smokeless ammunition compared to aged Damascus.^[25]^[1] These alloys ensure reliable performance in contemporary designs while maintaining the guns' traditional functionality.^[3]

Firing Mechanisms

Combination guns primarily employ break-action designs, where the barrels hinge open at the breech for loading and unloading, secured by a robust locking mechanism to withstand the pressures from both rifle and shotgun cartridges. The hinge pin, often positioned near the bottom of the action, allows the barrels to pivot downward when released by a top-lever or side-lever, while locking is achieved through systems like the Westley Richards top-lever with a rotary bolt or Purdey's double under-bolts, ensuring alignment and safety under recoil.^[26]^[1] Reloading is facilitated by either extractor or ejector systems integrated into the breech face. Extractors, introduced for centerfire ammunition in the 1860s, partially lift spent cases from the chambers to allow manual removal, as seen in early designs by George H. Daw, making them suitable for lighter hunting loads where full ejection is unnecessary.^[26] Ejectors, patented by Charles Needham in 1874 and refined by Deeley with fore-end mechanisms, forcefully expel empty shells upon opening the action using stored energy from the mainspring or dedicated springs, a feature standard in higher-grade combination guns for quicker follow-up shots in the field.^[26]^[1] Barrel selection in multi-barrel configurations, such as drillings, is managed through mechanical switches or dual-trigger setups to designate which barrel fires. Dual triggers allow independent control, with the front typically assigned to the rifle barrel and the rear to a shotgun barrel, while a tang-mounted selector lever shifts the front trigger's function between barrels, as in Sauer drillings where it also raises a rear sight for rifle use.^[2]^[1] Single selective triggers, common in American models like the Savage Model 24, use a sliding button behind the top-lever to toggle between barrels without altering trigger pull.^[1] Ignition systems in combination guns have evolved from early percussion and pinfire mechanisms to modern centerfire designs. Flintlock swivel guns, used in 18th-century prototypes, relied on external hammers striking frizzens for spark ignition, but by the 1860s, pinfire cartridges by Casimir Lefaucheux enabled internal hammers.^[26] The shift to hammerless actions began with Daw's 1862 hammerless action and culminated in the Anson & Deeley design of 1875, featuring rebounding hammers that reset after firing to prevent accidental discharge, now standard in contemporary models for reliable rimfire and centerfire operation.^[26] Safety features address the unique stresses of multi-barrel configurations, including transfer bars and manual selectors. Transfer bars, integrated into hammer mechanisms, block the firing pin unless the trigger is fully pulled, preventing inertial discharges in dropped guns, a critical enhancement in break-action designs.^[27] Manual safeties, often tang-mounted or Greener-style slide buttons on the top strap, engage by blocking hammer fall or sear movement, with barrel selectors incorporating interlocks to avoid firing the wrong barrel under stress, as in models pairing a .30-06 rifle with a 20-gauge shotgun.^[2]^[1]

Types

Combination Guns

A combination gun is a two-barreled firearm that incorporates one rifled barrel for bullets and one smoothbore barrel for shot or slugs, typically configured in an over-under arrangement to offer versatility for pursuing small game.^[14] This setup enables users to address varied hunting scenarios with a single weapon, such as targeting small mammals or birds without needing to switch firearms.^[1] Prominent examples include the Savage Model 24, which features a .22 Long Rifle rifled barrel over a .410 bore smoothbore barrel and was manufactured by Savage Arms from 1950 to 2010.^[28] An earlier design, the Marble Game Getter, introduced in 1909, employed a takedown mechanism for compact storage and transport.^[29] These guns commonly pair a .22 rimfire rifle barrel with a .410 shotgun bore, facilitating lightweight portability for field use.^[30] Their key benefits include overall compactness and adaptability, making them well-suited for upland bird and varmint hunting where mobility and rapid target switching are essential.^[31] Side-by-side configurations serve as less prevalent alternatives in some designs.^[14]

Cape Guns

Cape guns are side-by-side combination firearms featuring two horizontally arranged barrels—one rifled for bullets and one smoothbore for shotgun shells—specifically adapted for versatile hunting in African environments where diverse game is common. These guns provide the flexibility to engage small game or birds with 12-gauge shotgun loads while employing rifle cartridges for larger animals, often in powerful calibers like the .375 H&H Magnum for stopping dangerous charges.^[14]^[1]^[32] Developed primarily in Europe but popularized in Southern Africa following European settlement in the Cape Colony during the 17th and 18th centuries, Cape guns became essential tools for hunters facing unpredictable wildlife, including dangerous species like lions and elephants. Post-1900 advancements in cartridge technology, such as the 1912 introduction of the .375 H&H Magnum, enabled reinforced designs suitable for big-game pursuits in regions with varied terrain and climate, enhancing their role in stopping power scenarios.^[1]^[32]^[33] Notable examples include custom builds by European makers like Westley Richards, who produced 12-gauge Cape guns with integrated express sights for rapid target acquisition during close-range encounters, and historical pieces like the Thomas Lee percussion model from the mid-19th century, adapted with rifled barrels for African game up to Cape buffalo. Unique features of these guns often include strengthened actions to withstand the recoil of large calibers in humid conditions, along with double triggers for selective firing, distinguishing them from vertical over-under layouts in other combination designs.^[34]^[35]

Drillings

A drilling is a three-barreled combination gun originating from German firearm design, typically consisting of two side-by-side smoothbore shotgun barrels—often in 16- or 20-gauge—positioned over a central rifled barrel chambered for cartridges like the 9.3x74R.^[14]^[36] This layout, known as a "forester's gun," allows for versatile use in mixed terrain hunting, enabling quick switches between shot for birds or slugs and rifle rounds for larger game without changing weapons.^[36] The design emphasizes balance and compactness, with the rifle barrel's placement beneath reducing muzzle rise and aiding handling.^[37] Notable early models include the Sauer Drilling, developed by J.P. Sauer & Sohn in the late 19th and early 20th centuries, which introduced innovations such as a self-cocking mechanism with a separate cocking lever for the backlock in 1895.^[38] Sauer's Model 30, launched in 1930 and also produced in a lighter steel variant (Model 30 L), became a benchmark for quality craftsmanship.^[38] A military adaptation, the M30 Luftwaffe Drilling, was selected in 1941 for downed aircrews during the North African campaign; it featured 12-gauge shotgun capability alongside the 9.3x74R rifle barrel and was issued in survival kits with ammunition and accessories.^[39]^[38] Drillings commonly utilize a bascule break-action mechanism, where the barrels tilt downward to load and eject, engineered to withstand the higher pressures from the rifle cartridge while maintaining reliability for the smoothbores.^[37]^[19] Trigger systems typically involve two triggers: the front for the shotgun barrels and the rear—often pushed forward for selection—for the rifle barrel, allowing selective firing without ambiguity in the field.^[40]^[41] Some models incorporate a top-tang selector switch to designate the active barrel, enhancing safety and precision during hunts.^[20] Pre-World War II production of drillings was substantial among German makers in Suhl, reflecting their status as a staple for European hunters; for instance, J.P. Sauer & Sohn manufactured models like the Drilling Model 32 from 1931 onward, while Imman. Meffert Gewehrfabrik produced approximately 1,000 units annually before 1939 using lightweight Dural aluminum actions.^[38]^[42] This output, across multiple firms including Merkel and Krieghoff, underscores the drilling's widespread adoption for its multi-purpose utility.^[42] Rarer extensions to four barrels, known as vierlings, build on this foundation but introduce greater complexity.^[14]

Vierlings

A Vierling is a rare four-barreled combination gun, typically featuring two shotgun barrels and two rifle barrels of differing calibers, arranged in specialized configurations such as over-under pairs for the shotgun barrels paired with side-by-side rifle barrels, or occasionally in a square four-barrel cluster.^[21] These firearms originated primarily in Germany and Austria, where master gunmakers crafted them as versatile hunting tools capable of handling diverse game with both rifled and smoothbore options in a single weapon.^[21] The design allows for selective firing, often with a mechanical selector to choose between barrel sets, emphasizing precision regulation to ensure point of impact alignment across all barrels.^[22] Notable historical examples include the British Charles Lancaster four-barrel hammerless breechloading rifle-carbine from the late 1800s, chambered in calibers like .44 Winchester and exemplifying early multi-barrel innovation for colonial hunting.^[43] In the German tradition, the Merkel Vierling represents a high-end model, often configured with powerful rifle calibers such as .470 Nitro Express alongside 20-gauge shotgun barrels, showcasing the blend of double rifle and over-under shotgun elements.^[14] These guns were bespoke creations, with production confined to elite workshops due to the intricate craftsmanship required. The mechanical challenges of Vierlings stem from their four-barrel arrangement, particularly the complexity of extractor systems designed to simultaneously handle spent casings from mixed rifled and smoothbore barrels without jamming or misalignment.^[44] Regulating the barrels for consistent accuracy adds further difficulty, as does the need for robust locking mechanisms to withstand repeated firing sequences, limiting them to custom, high-end production rather than mass manufacturing.^[22] Vierlings are extremely rare, with historical estimates suggesting fewer than 1,000 examples produced, primarily commissioned for European nobility and affluent hunters pursuing driven game in varied terrains.^[14] As an extreme extension, five-barreled Fünflings represent even greater rarity in this lineage.^[31]

Fünflings

The fünfling, derived from the German word for "quintuplet," denotes an exceedingly rare variant of the combination gun featuring five barrels, designed to offer unparalleled versatility in a single firearm for specialized hunting needs.^[14] These custom pieces typically integrate multiple rifled and smoothbore barrels in intricate arrangements, such as a cluster of rifle barrels encircling or overlaying a central shotgun tube, allowing rapid switching between calibers for varied game without reloading.^[45] A prominent historical example is the circa 1890 fünfling crafted by Peter Oberhammer of Munich, Germany, which employs four rifle barrels—chambered in 9.3x82R, two in 9.1x52R, and one in 11x74R—arranged in a semicircular formation above a 16-gauge smoothbore shotgun barrel, complete with a patented barrel selector switch for sequential firing.^[45] This configuration exemplifies the fünfling's emphasis on multi-caliber capability, evolving directly from the four-barrel vierling to accommodate even more diverse quarry in a compact, break-action frame.^[14] Originating in late 19th- and early 20th-century Europe, fünflings were bespoke commissions for wealthy estate owners pursuing ultra-versatile driven hunts across mixed terrains and game species, where quick adaptation between shot and rifle fire was prized.^[14] However, their fabrication demanded exceptional gunsmithing prowess, resulting in prohibitive costs and excessive weight often surpassing 10 pounds, which rendered them impractical for all but the most dedicated sportsmen.^[45] Consequently, fünflings number among the rarest combination guns, with only a handful of authenticated specimens documented globally, such as the singular Oberhammer example that fetched $25,200 at auction in 2021.^[45]

Uses and Applications

Hunting and Sporting

Combination guns offer significant versatility for hunters pursuing mixed game in a single outing, enabling seamless transitions between rifle barrels loaded with slugs or bullets for larger animals like deer and shotgun barrels charged with shot for birds or small game, without the burden of carrying separate firearms. This design is particularly advantageous in dynamic field conditions where opportunities for different species arise unpredictably, such as in wooded areas where a hunter might encounter both upland birds and varmints. For instance, the over/under configuration allows for quick barrel selection via a shared trigger mechanism, enhancing efficiency during pursuits that blend small and big game hunting.^[46]^[2] In European regional practices, drillings—three-barreled combination guns with two shotgun barrels over a rifle—have long been favored in driven hunts, a traditional method where beaters flush game toward stationary hunters in dense forests like Germany's Black Forest or Tyrolean Alps. These firearms support rapid shifts from shot for flushing birds such as grouse and quail to rifle fire for larger quarry like deer, stags, or boar, aligning with the continent's emphasis on multi-species hunts in varied terrain. The configuration reflects centuries-old customs, including engravings honoring St. Hubertus, the patron saint of hunters, and remains integral to organized drives where game density demands adaptability.^[20]^[2] In the United States, combination guns like the Savage Model 24 are commonly employed for small game hunting, providing a lightweight, packable option for pursuits involving squirrels, rabbits, and game birds in backcountry or farm settings. Chambered in pairings such as .22 LR over .410 bore, these guns excel in varmint control and upland bird hunts, allowing hunters to address diverse small game with one reliable tool suited to American woods-running traditions. Their compact 41-inch length and 7-pound weight make them ideal for extended walks where versatility trumps specialization.^[46] While combination guns are not standard in formal three-gun competitions—which typically require separate handguns, rifles, and shotguns for multi-discipline stages—adaptations exist in some sporting clays events and informal multi-gun matches where over/under designs with shotgun capabilities can substitute for dedicated scatterguns, offering barrel-switching for varied target presentations. These applications highlight the guns' role in recreational shooting that simulates field versatility, though participants often prioritize dedicated firearms for competitive speed.^[47]^[48] Legal aspects of combination guns in hunting and sporting contexts include caliber restrictions and proofing requirements that vary by jurisdiction to ensure safety and compliance. In the European Union, multi-barrel firearms like drillings must undergo proofing at authorized houses to test barrel integrity under high-pressure stresses from differing calibers, with marks indicating compliance for calibers such as 16-gauge shot over 7x57R rifle; modifications, like chamber lengthening, necessitate re-proofing. Countries enforce hunting-specific limits, such as prohibitions on certain large-caliber rifles in semi-automatic configurations or magazine capacities exceeding 10 rounds for long guns, to regulate multi-game pursuits while adhering to Directive (EU) 2021/555 standards. In the US, federal and state laws generally permit common pairings like .22/.410 without unique restrictions beyond standard firearm regulations, though some states impose caliber minimums for big game.^[49]^[50]^[51]

Military and Survival

Combination guns have found niche applications in military and survival contexts, particularly as compact, versatile tools for aircrews and spacefarers facing potential stranding in remote or hostile environments. Originating from civilian hunting designs that emphasized multi-purpose utility in a single firearm, these weapons were adapted for scenarios where downed pilots or returning cosmonauts might need to hunt small game, deter wildlife, or provide self-defense without the burden of separate rifles and shotguns.^[14] During World War II, the German Luftwaffe issued the Sauer M30 Drilling to pilots as a survival weapon for use after being shot down behind enemy lines or in isolated areas. This triple-barrel combination gun featured two 12-gauge shotgun barrels over a 9.3x74mmR rifle barrel, allowing for both small game hunting with shot and larger threats with the rifle round, all in an approximately 42-inch overall length weighing about 7.5 pounds.^[39]^[52] The design prioritized reliability in adverse conditions, with a break-action mechanism and dual triggers for selective firing, making it suitable for Luftwaffe aircrew packs during missions over Europe and North Africa.^[39]^[52] In the Cold War era, the United States developed the M6 Aircrew Survival Weapon as a lightweight option for Air Force pilots, evolving from earlier survival rifle concepts to address foraging needs in potential crash scenarios. Chambered in .22 Hornet atop a .410 bore shotgun, the over-under break-action design measured just 14 inches in barrel length and weighed approximately 4.4 pounds, enabling easy storage in ejection seat kits or aircraft survival packs.^[53]^[54]^[55] Issued during the Vietnam War and beyond, it supported aircrews in jungle environments by providing quiet small-game capabilities with the rimfire-equivalent Hornet round—often fitted with optional suppressors for stealthy hunting—and broader shotgun utility for birds or defense against larger animals.^[53]^[54] The Soviet Union similarly equipped cosmonauts with the TP-82, a three-barreled survival pistol carried aboard Soyuz missions from the 1980s until its retirement in 2006 due to discontinued specialized ammunition production. This 14-inch overall weapon combined a 5.45x39mm rifle barrel with two upper 12.5x70mm smoothbore barrels equivalent to approximately 40-gauge shotgun loads, detachable stock doubling as a machete, and a total weight of approximately 3.5 pounds (without stock) for inclusion in re-entry survival kits.^[56]^[57] Intended for post-landing survival in Siberia's vast taiga or other remote landing zones, it was replaced by the standard Makarov PM pistol, reflecting a shift away from combination designs.^[56]^[57] The overarching rationale for these military combination guns emphasized portability and multifunctionality, ensuring aircrew and astronaut packs remained under 10 pounds while offering rimfire-level quiet operation for small game—via suppressors on .22-caliber barrels where applicable—and shotgun power for varied threats, without compromising on ruggedness for extreme survival conditions.^[58]

Modern Developments

Contemporary Manufacturers

Contemporary manufacturers of combination guns primarily consist of a select group of specialized producers focusing on niche markets for hunting, sporting, and survival applications. Italian-based Chiappa Firearms offers the Double Badger series, a compact, folding over/under design introduced in the 2010s that pairs a .410 bore shotgun barrel with a .22 LR rifle barrel for versatile small-game use.^[59] A higher-powered variant combining .243 Winchester and .410 gauge was added to the lineup in 2019, emphasizing affordability and portability for outdoor enthusiasts.^[60] In the United States, Thompson/Center Arms provides the Contender platform, a break-action single-shot system with interchangeable barrels that enable rifle-shotgun combinations across various calibers, such as .22 LR with .410 bore or larger rifle options like .30-30 Winchester.^[61] Originally launched in 1967, the Contender remains available through custom builds and aftermarket support, appealing to modular customization trends in modern shooting. In 2025, Thompson/Center announced the revival of full production for the Contender.^[62] German firm Merkel continues traditional production of combination guns, including the BBF B4 model in the Meisterstück line, chambered in combinations like 12 gauge over 7x65R or 9.3x74R rifle barrels—calibers suitable for nitro express-style big-game hunting.^[36] Introduced as part of an expanded range in 2018, these over/under designs maintain Merkel's reputation for precision craftsmanship in limited-series manufacturing.^[63] Russian manufacturer Kalashnikov Concern, via its Baikal brand (successor to Izhmash), produces survival-focused variants like the IZH-94, an over/under combination gun in 12 gauge and 7.62x39mm rifle, designed as a compact alternative to the discontinued TP-82 pilot survival weapon.^[64] This model supports modular barrel sets for adaptability in remote or emergency scenarios. In 2024, Turkish manufacturer Balikli Arms introduced affordable over/under combination guns, such as models in .223 Remington over 12 gauge, targeting the North American market following import restrictions on Baikal products.^[65] Overall production emphasizes modular designs for caliber customization, reflecting a niche global output suited to specialized demand rather than mass-market volumes.^[65] In the U.S. market, pricing spans from approximately $400 for entry-level options like the Chiappa Double Badger to $5,000–$10,000 for bespoke European models such as Merkel combination guns.^[66] Sales of survival-oriented combination guns surged post-2020, aligning with broader firearm purchase peaks driven by preparedness concerns, though overall industry volumes have moderated since.^[67]

Technological Advancements

Modern combination guns have incorporated synthetic stocks to enhance durability and reduce weight compared to traditional wood, as seen in the Savage Arms 42 Takedown model, which features a matte black synthetic stock for improved weather resistance and lighter carry in field conditions. While carbon fiber and titanium components are prevalent in contemporary bolt-action rifles for up to 40% weight savings in military applications, their adoption in combination guns remains limited to custom builds, prioritizing the balance required for break-action designs.^[68] These materials contribute to overall portability without compromising the structural integrity needed for multi-barrel configurations. Caliber evolutions in combination guns have expanded versatility, with modern examples pairing rimfire rifle barrels like .22 LR or .22 WMR over .410 bore shotgun barrels, as in the Savage 42 Takedown, allowing seamless switching between small game hunting and birdshot applications.^[69] Higher-powered pairings, such as 12-gauge over .223 Remington or .30-06 Springfield in Baikal models, support diverse hunting scenarios.^[1] Digital aids have been integrated into combination guns through low-profile optic mounts, enabling red dot sights on rifle barrels for quick target acquisition without disrupting the gun's balance, as recommended for break-action models to maintain handling dynamics.^[70] Prototypes featuring smart selectors with electronic safeties, such as biometric locks, are emerging in broader firearm innovation to prevent unauthorized use, though application to combination guns is still experimental and focused on enhancing safety in multi-caliber platforms.^[71] Updates on legacy survival designs include the replacement of the Soviet TP-82 cosmonaut pistol—a 9mm rifle/12-gauge shotgun combination—with standard military sidearms like the Makarov PM around 2007, shifting emphasis from specialized multi-barrel tools to compact pistols for post-landing emergencies.^[72] Ballistic improvements in modern combination guns incorporate recoil-reducing features like hydraulic pads or LimbSaver inserts, which can absorb up to 70% of felt recoil in shotgun components, improving shooter comfort during extended use without altering the break-action mechanism.^[73]
