Smith & Wesson Model 351C
Smith & Wesson · Pistol · In Production · 2004
Also known as: 351C AirLite, 351 Centennial
Overview
The Smith & Wesson Model 351C is a lightweight J-frame snubnose revolver chambered in .22 Winchester Magnum Rimfire, introduced in 2004 as part of Smith & Wesson's AirLite series offering centerfire-equivalent power in a rimfire package. The 'C' designation indicates Centennial-style configuration, featuring an enclosed hammer and double-action-only operation optimized for snag-free concealed carry. Weighing just 11 ounces empty, the 351C is built on the compact J-frame platform with an aluminum alloy frame that provides strength while minimizing weight. The seven-shot cylinder capacity represents a significant advantage over traditional five-shot .38 Special J-frames, giving users 40 percent more ammunition capacity in a package of comparable size and weight. Built with a 1.875-inch stainless steel barrel, the 351C features XS Sights white-dot front sight paired with a fixed U-notch rear sight, providing a clear sight picture despite the compact dimensions. The hammerless design, technically featuring an internal hammer shrouded within the frame contour, eliminates snagging hazards during draws from pockets, ankle holsters, or purses. The aluminum alloy frame construction delivers weight savings compared to steel while maintaining durability for the lower chamber pressures of .22 WMR ammunition (24,000 PSI versus 35,000 PSI for .357 Magnum). The 351C provides an alternative for shooters seeking ultra-lightweight carry with minimal recoil, making it suitable for recoil-sensitive users or as a backup gun where shot placement is prioritized over stopping power.

Notes
The Model 351C was designed as Smith & Wesson's answer to the growing demand for extremely lightweight concealed carry revolvers with minimal recoil. The .22 Winchester Magnum Rimfire cartridge, developed in 1959, offers significantly more energy than .22 Long Rifle while still generating manageable recoil in ultra-lightweight firearms. From the short 1.875-inch barrel, .22 WMR ammunition typically produces muzzle velocities around 1,100-1,200 feet per second with 40-grain bullets, delivering approximately 250-280 foot-pounds of energy. The seven-shot capacity partially compensates for the smaller caliber, providing more opportunities for accurate shot placement. The aluminum alloy frame, while durable for rimfire pressures, requires more care than steel frames to avoid damage from impacts or drops. The double-action-only trigger pull typically measures 11-13 pounds, heavier than centerfire J-frames but considered manageable for a pocket revolver. The Centennial-style hammerless configuration was originally introduced by Smith & Wesson in 1952, designed for concealment and preventing hammer-bite during rapid fire. The 351C is often compared to the Ruger LCR in .22 WMR and the NAA mini-revolvers, though the Smith & Wesson offers superior capacity and ergonomics. Many users appreciate the 351C for training new shooters or as a companion to larger-caliber carry guns for situations requiring ultra-deep concealment.
Background
The 351C proved that 'mouse gun' didn't have to mean compromise. While firearms instructors debated the adequacy of .22 WMR for defense, the 351C quietly became a favorite among those who actually carried guns daily-private investigators, plainclothes detectives, and women seeking a truly pocketable option they would actually have with them when needed.
