Hammerli Arms 5170502 .22 LR 4.25" 13-Round Threaded Barrel Pistol

The Hammerli Arms 5170502 .22 LR 4.25" 13-Round Threaded Barrel Pistol is a precision-engineered rimfire platform purpose-built for shooters who demand accuracy and modularity in a compact package. Designed for competitive sport shooters, firearms trainers, and recreational marksmen, this pistol combines Swiss engineering with practical features that allow for suppressor integration and customization. The threaded barrel—a critical advantage for sound reduction and signature control—distinguishes this platform from conventional .22 LR handguns and makes it ideal for dedicated training at indoor ranges where noise management matters.

Built on Hammerli's reputation for match-grade reliability, the 5170502 features a 4.25-inch threaded barrel chambered in .22 Long Rifle, a cartridge renowned for low recoil, minimal muzzle rise, and cost-effective practice ammunition. The 13-round magazine capacity delivers practical capacity for extended shooting sessions without excessive reload cycles, while the threaded barrel accepts standard 1/2x28 pitch suppressors for hearing-safe operation. The compact 8.6-inch overall length and 3.57-pound weight class it as a highly maneuverable training tool, making it equally suited for dry-fire practice, transition drills, or marksmanship fundamentals development in a home or range environment.

Law enforcement academies, civilian defensive shooting instructors, and competitive shooters benefit most from the precision and suppressor-ready design of this Hammerli platform. The .22 LR chambering ensures budget-friendly high-volume training without the fatigue factor of centerfire recoil, while the threaded barrel immediately positions users for sound mitigation in shared shooting environments. Compatibility with standard .22 LR ammunition and readily available rimfire suppressors makes this pistol a practical foundation for serious shooters building a hearing-safe training regimen or establishing baseline shooting skills before transitioning to service-caliber platforms.
