Smith & Wesson Model 1
The Smith & Wesson Model 1 is a single-action, tip-up revolver chambered in .22 Short rimfire, featuring a seven-shot cylinder and designed as a compact pocket pistol.[1][2] Introduced in 1857 as the company's first product, it was the initial commercially viable repeating handgun to employ self-contained metallic cartridges, supplanting the cumbersome percussion cap and loose powder loading of prior designs.[1][3] Developed by partners Horace Smith and Daniel B. Wesson in response to Rollin White's 1855 patent for a bored-through cylinder that enabled rear-loading cartridges, the Model 1—originally termed the "Seven Shooter"—rapidly gained popularity for its simplicity and reliability.[4] Production spanned three distinct issues from 1857 to 1882, yielding nearly 260,000 units, with the first issue alone accounting for about 11,000 examples manufactured between 1857 and 1860.[1][2] Its demand surged ahead of and during the American Civil War, seeing use among Union and Confederate personnel as well as civilians for self-defense and target practice, though its small caliber limited it primarily to a secondary or concealable role.[5] The revolver's innovative tip-up barrel facilitated straightforward cartridge insertion and ejection without tools, while its frame—typically iron in early issues, later steel—measured around 6.5 inches overall with a 3.25-inch barrel, emphasizing portability over power.[1][6] This design not only propelled Smith & Wesson to prominence but also catalyzed the broader firearms industry's shift toward metallic cartridge systems, influencing subsequent models and establishing foundational revolver mechanics still echoed in modern arms.[1][4]Development and Origins
Founding of Smith & Wesson
Horace Smith and Daniel B. Wesson established their partnership in 1852 in Norwich, Connecticut, with the aim of designing and manufacturing firearms capable of using fully self-contained metallic cartridges, a significant innovation over black powder percussion systems.[7] This collaboration built on earlier experiments with repeating mechanisms, leading to their involvement in the Volcanic Repeating Arms Company, where they produced the .41 rimfire Volcanic pistol in 1854, recognized as one of the first American repeating handguns.[5] The partnership's focus on cartridge-based designs addressed longstanding limitations in reloading speed and reliability, setting the stage for cartridge revolvers.[7] By 1856, after divesting from the Volcanic venture due to financial challenges, Smith and Wesson relocated to Springfield, Massachusetts, and formally organized the Smith & Wesson Revolver Company to capitalize on the expiration of Samuel Colt's dominant revolver patent and to exploit Rollin White's 1855 patent for a bored-through cylinder that enabled rimfire cartridge loading from the rear.[5] They secured an exclusive license for White's patent, investing $10,000 in royalties over the patent's life to ensure monopoly on the design, which proved pivotal as it allowed seamless integration of metallic cartridges without the need for loose powder or caps.[7] This founding emphasized precision manufacturing and legal protection of intellectual property, distinguishing the company from competitors reliant on cap-and-ball technology.[5] The new entity's initial production centered on small-frame revolvers, culminating in the 1857 introduction of the Model 1, a .22 Short rimfire, seven-shot tip-up design that validated their cartridge system and propelled the company toward commercial success amid rising demand during the lead-up to the American Civil War.[7] Early challenges included securing capital and navigating patent disputes, but the founders' mechanical expertise—Smith as an inventor with prior firearm experience and Wesson as a skilled gunsmith—enabled rapid prototyping and refinement.[5] This foundation not only launched Smith & Wesson's enduring legacy in revolver innovation but also influenced broader firearm evolution by prioritizing self-contained ammunition.[7]Key Patents and Innovations
The foundational innovation for the Smith & Wesson Model 1 was Rollin White's U.S. Patent No. 12,648, issued on April 3, 1855, which claimed a revolver cylinder bored straight through from front to rear, permitting the insertion and extraction of metallic cartridges from the rear without obstruction by a breechplate.[8] This design addressed longstanding challenges in repeating firearms by enabling reliable self-contained ammunition, specifically rimfire cartridges, to be used in a revolver configuration.[9] Smith and Wesson acquired an exclusive license to manufacture under this patent, agreeing to pay White a royalty of 25 cents per revolver produced, which granted them a temporary monopoly on cartridge-loading revolvers until the patent's expiration in 1869.[10][11] Building on White's cylinder patent, Horace Smith and Daniel B. Wesson innovated the Model 1's tip-up barrel mechanism, which allowed the barrel to pivot upward along the top strap, exposing the rear of the cylinder for simultaneous loading of all seven .22 Short rimfire chambers. This feature, integrated into the first production models beginning in 1857, simplified reloading compared to percussion revolvers and contributed to the firearm's commercial viability, with approximately 11,000 First Issue units manufactured by 1860.[6] The combination of the bored-through cylinder and tip-up design marked the Model 1 as the first American revolver to successfully employ integrated metallic cartridge technology, paving the way for modern handgun evolution.[5] Subsequent refinements in later issues included frame modifications for improved durability, such as the rounded frame in the Second Issue (1860–1868), but these built directly upon the core patent-enabled cartridge system without requiring additional groundbreaking patents from Smith & Wesson themselves.[12] The White patent's enforcement through litigation against infringers, including major competitors, underscored its causal role in sustaining Smith & Wesson's market dominance during the Civil War era.[9]Initial Design Challenges
The primary initial design challenge for the Smith & Wesson Model 1 revolver stemmed from the need to secure Rollin White's April 3, 1855, patent for a cylinder bored through from the rear, which enabled loading self-contained metallic cartridges without removing the barrel or cylinder. Prior revolver designs, such as those by Samuel Colt, relied on percussion caps and awkward loading methods, but White's innovation was essential for practical cartridge revolvers; however, it faced initial skepticism and legal undervaluation, with Colt declining to purchase rights for $1.1 million. On November 17, 1856, Horace Smith and Daniel B. Wesson obtained exclusive U.S. manufacturing rights, agreeing to pay White a royalty of $0.25 per revolver produced, a financial burden for their startup but granting monopoly protection against competitors until the patent's 1869 extension disputes.[9][8][11] Developing reliable .22 Short rimfire cartridges posed another hurdle, as earlier attempts like the Volcanic Repeating Arms' rocket-ball ammunition—featuring a hollow base ignited from the rear—proved underpowered and prone to misfires due to inconsistent combustion. Inspired by Louis-Nicolas Flobert's 1845 parlor gun cartridges, Wesson refined the rimfire design with priming compound in the cartridge rim for hammer ignition, but early iterations suffered from weak primers and variable powder charges, necessitating extensive experimentation to ensure ignition reliability in a seven-shot cylinder under rapid fire conditions. This cartridge, introduced alongside the Model 1 in 1857, marked the first successful American rimfire metallic round, though initial batches required quality improvements to minimize hangfires and duds.[13][14] Mechanically, the tip-up barrel frame demanded precise machining for barrel-cylinder alignment and secure latching, as misalignment could lead to gas leakage, cylinder binding, or off-center hammer strikes piercing the thin rims. The small .22-caliber components amplified tolerances issues in an era of rudimentary tooling, with the single-action hammer and spur trigger requiring exact fitting to prevent timing failures. Production commenced in 1857 with limited machinery, resulting in early quality inconsistencies that delayed scaling; despite these, over 2,500 units sold in 1858, reflecting iterative design fixes to the prototypes' flaws before full First Issue output reached 11,375 by 1860.[6][15]Design and Technical Features
Mechanism and Operation
The Smith & Wesson Model 1 is a single-action revolver, requiring the hammer to be manually thumb-cocked to rotate the cylinder, cock the internal mechanism, and align a chamber with the barrel before the trigger can release the hammer for firing.[6] This design lacks a trigger guard and relies on the shooter's control to prevent accidental discharge.[6] Loading proceeds by depressing the knurled latch on the left frame, which unlocks and pivots the barrel upward 90 degrees, as the arbor pin supporting the cylinder is affixed to the barrel assembly.[6] The seven-shot cylinder, featuring fluted chambers bored straight through its axis per Rollin White's 1855 patent (U.S. Patent No. 474), can then be slid forward off the exposed pin for direct access to insert .22 rimfire cartridges into each chamber.[6] After loading, the cylinder is reinstalled, and the barrel is lowered to latch securely, locking the assembly.[6] In operation, cocking the hammer advances the cylinder via a pawl-and-ratchet system, indexing the next loaded chamber while forcing the cartridge base forward against the barrel to minimize gas escape.[6] The hammer's firing pin then strikes the rim of the aligned cartridge upon trigger pull, igniting the primer compound embedded in the case rim to propel the bullet.[6] This bored-through cylinder innovation, licensed from White, enabled reliable rearward ignition of self-contained metallic cartridges, supplanting cap-and-ball systems.[6]Caliber, Capacity, and Specifications
The Smith & Wesson Model 1 revolver is chambered in .22 Short rimfire, the first widely successful self-contained metallic cartridge designed for revolvers, introduced in 1857 to pair with this model.[16][6] The cartridge propelled a 29-grain lead bullet at approximately 700 feet per second, prioritizing low recoil and suitability for a compact pocket pistol.[6] Its cylinder holds seven rounds, a capacity enabled by the small caliber and rimfire ignition system that eliminated the need for percussion caps or central priming.[6][17] This multi-shot design marked a departure from contemporary single-shot derringers, offering repeated fire without manual reloading of individual chambers.[6] Key specifications include a standard barrel length of 3 3/16 inches (approximately 3.25 inches in some measurements), a single-action mechanism requiring manual cocking of the hammer for each shot, and a spur trigger without a guard for compactness.[6][17] The frame transitioned from brass in early First Issue production to iron or steel in later Second and Third Issues, with rosewood or walnut grips shaped in a bird's-head configuration for concealed carry.[6] Overall, the revolver weighs around 10-11 ounces unloaded, depending on the issue and materials, emphasizing portability as a self-defense tool.[18]| Specification | Details |

Materials and Manufacturing Techniques
The first and second issues of the Smith & Wesson Model 1 featured frames cast from brass, which were typically nickel-plated to improve durability and appearance. Barrels were fabricated from iron in an octagonal configuration, measuring approximately 3 3/16 inches in length, while cylinders were machined steel, unfluted, and designed to hold seven .22 Short rimfire rounds. Grips consisted of varnished rosewood panels, hand-fitted and serial-number matched to ensure proper alignment before final metal finishing.[6][18] The third issue introduced a cast iron frame for superior strength over brass, paired with a round-ribbed steel barrel and a fluted steel cylinder. Production techniques across issues relied on casting for frames, forging followed by precision machining for barrels and cylinders, and manual assembly with hand-fitting of internal components and grips, enabling limited interchangeability amid the transition from craft-based to early industrial methods in the 1850s and 1860s. Rifling evolved from three left-hand grooves in early first-issue examples to five right-hand grooves by later variants, optimizing bullet stabilization. Blued finishes applied to steel parts complemented the plating on brass frames in initial production.[6][19]Production Variants
First Issue (1857–1860)
The First Issue of the Smith & Wesson Model 1 revolver was manufactured from 1857 to 1860, representing the company's debut production of a cartridge-loading handgun. This model utilized the .22 Short rimfire cartridge, a seven-shot cylinder, and a tip-up barrel mechanism, enabled by Horace Smith's design and Rollin White's patented bored-through cylinder. Approximately 11,671 units were produced, with serial numbers ranging from 1 to 11,671 stamped on the bottom of the grip frame.[2][20] Early production featured a rounded frame profile and a flat-spring barrel latch positioned on top of the barrel. The initial First Type variant, limited to about 225 examples (serial numbers 1–225), included a recoil shield that rotated with the cylinder and lacked a separate plate, alongside a simple barrel catch without a screw forward of the trigger guard. Subsequent refinements within the First Issue incorporated a fixed recoil shield and adjusted cylinder stop notches from round to rectangular for improved engagement. Barrels measured 3.25 inches, with octagonal shaping and typical markings including "SMITH & WESSON SPRINGFIELD, MASS. PAT'D APRIL 3D 1855" on the top strap.[21][22] Manufacturing occurred at the firm's Springfield, Massachusetts facility, where initial output in 1857 was modest, with only a handful of prototypes assembled before scaling to over 2,500 units by 1858. The revolver retailed for around $12.50 in 1860, reflecting its novelty as the first practical repeating firearm not requiring separate percussion caps or powder charges. Production ceased in 1860 to transition to the Second Issue, which addressed design feedback while continuing serial numbering from 11,672.[6][1]Second Issue (1861–1868)
The Second Issue of the Smith & Wesson Model 1 revolver represented refinements to the original design, produced primarily from 1861 to 1868 with serial numbers continuing from the First Issue, ranging approximately from 15,001 to 126,361.[23][21] This variant featured a larger, irregularly shaped side plate replacing the rounded one of the First Issue, along with a flatter frame profile that enhanced structural integrity and simplified manufacturing.[24] The revolver retained the tip-up barrel mechanism, seven-shot capacity in .22 rimfire caliber, and octagonal barrel, but these modifications addressed early production limitations observed in the initial 11,671 units.[12] Approximately 115,000 Second Issue revolvers were manufactured, with production peaking during the American Civil War years due to increased demand for compact, reliable firearms.[25] Serial number ranges by year included 15,001–22,000 in 1861, 22,001–26,000 in 1862, 26,001–40,000 in 1863, 40,001–50,000 in 1864, and continuing through higher numbers until 1868.[23] Markings typically included patent dates of 1855, May 3, 1859, and September 14, 1860, stamped on the frame or barrel, with occasional examples bearing "2D QUAL'TY" designations indicating second-quality production.[6] These revolvers were constructed with blued steel frames and barrels, rosewood or varnished hardwood grips, and a spurred hammer for improved handling, distinguishing them further from the First Issue's smoother contours.[24] The design's bored-through cylinder accommodated the rimfire cartridges without needing percussion caps, a key innovation that facilitated quicker reloading in field conditions.[12] While not a primary military sidearm due to its small caliber, the Second Issue saw civilian adoption and limited wartime use, contributing to Smith & Wesson's early reputation for metallic cartridge firearms.[25]Third Issue (1868–1882)
The Third Issue of the Smith & Wesson Model 1, manufactured from 1868 to 1882, introduced a substantial redesign focused on enhanced ergonomics and ease of carry compared to prior variants. This iteration featured a rounded birdshead grip profile, replacing the squarer configurations of the First and Second Issues, which improved handling comfort and facilitated quicker draws from a pocket or holster. Production totaled approximately 131,163 units, with serial numbers ranging from 1 to 131,163, marking a fresh numbering sequence independent of earlier issues to reflect the updated design.[26][27][24] Retaining the core tip-up barrel mechanism and .22 Short rimfire cartridge with a 7-shot fluted cylinder, the Third Issue emphasized refinements in frame aesthetics and assembly. The sideplate adopted a more streamlined, irregular shape for better access during maintenance, while the overall frame profile became flatter and more contoured. Early examples, roughly the first 8,000 to 9,000 units, incorporated a square topstrap for added rigidity, but subsequent production shifted to a rounded topstrap design around serial number 9,000, aligning with evolving manufacturing tolerances and user feedback on balance. Barrel lengths standardized at 3 3/16 inches initially, with shorter 2 11/16-inch options introduced in 1872 to cater to concealed carry preferences; finishes included blued steel or nickel plating, with optional mother-of-pearl grips and engraving available for premium models.[28][19][26] These changes addressed limitations in the Second Issue, such as the less intuitive grip geometry, while leveraging post-Civil War production efficiencies at Smith & Wesson's Springfield facility. The redesign coincided with the expiration of Rollin White's bored-through cylinder patent in 1869, though the Model 1's single-action, rimfire operation remained distinct from emerging centerfire competitors. Markings typically included "Smith & Wesson Springfield Mass." on the barrel and "Pat. July 10th 1855" referencing the foundational loading gate patent, underscoring continuity in intellectual property amid iterative improvements. Total output reflected sustained civilian demand for compact pocket revolvers, with no major military contracts, positioning the Third Issue as a bridge to S&W's later top-break models.[29][6][30]Historical Use and Popularity
Role in the American Civil War
The Smith & Wesson Model 1 revolver served primarily as a privately acquired backup firearm during the American Civil War (1861–1865), valued for its compact .22 Short rimfire design that enabled faster reloading than cap-and-ball competitors.[31][5] Its seven-shot capacity and self-contained metallic cartridges appealed to soldiers seeking a lightweight personal defense option, though the small caliber restricted it to supplementary roles rather than primary combat use.[18] Both Union and Confederate personnel obtained examples through individual purchases, with pre-war shipments exceeding 20,000 units by April 1861.[32] Production of the Second Issue variant, manufactured from 1861 to 1868, intensified amid wartime demand that outstripped factory output, leading Smith & Wesson to expand operations in Springfield, Massachusetts.[5][18] No official U.S. government contracts materialized for the Model 1, distinguishing it from larger revolvers like the Colt Army, but Union cavalry units such as the First New York Dragoons documented its field carry.[33] Confederate adoption occurred via Southern pre-war acquisitions and captures, with surviving examples confirming use by rebel soldiers.[32] Notable Union accounts include Private Charles Serritt of the 16th Kentucky Volunteers, who in a December 15, 1862, letter credited his Model 1 with killing two Confederates during service.[32] The revolver's portability suited officers and mounted troops in skirmishes, though ammunition supply challenges—tied to Smith & Wesson's own .22 rimfire production of over 43 million rounds by 1865—occasionally hampered reliability.[31] Overall, the Model 1 exemplified early cartridge firearm innovation amid the war's demands, bridging civilian ingenuity with military application without supplanting established percussion arms.[5]
