SIG Sauer P322 22lr 4" 10-Round Threaded Barrel Pistol

The SIG Sauer P322 22LR 4" 10-Round Threaded Barrel Pistol represents a purpose-built rimfire platform designed for shooters who demand reliability, modularity, and precision in a compact form factor. Purpose-built for training, recreational shooting, and low-recoil tactical applications, this .22 Long Rifle pistol delivers the ergonomics and controls of a modern service weapon without the felt recoil penalty. The threaded barrel design enables direct integration of suppressors and other muzzle devices, making it an ideal platform for shooters building a suppressed training rig or dedicated rimfire duty backup.

Built on SIG Sauer's proven modular pistol architecture, the P322 features a 4-inch threaded barrel with 1/2x28 TPI threading—the industry standard for .22 LR suppressors and muzzle devices. The 10-round magazine capacity balances firepower with concealability, while the lightweight polymer frame (2.5 lbs total) reduces fatigue during extended training sessions. The straight-blowback operating system ensures consistent point-of-aim, and the design supports standard Picatinny rail integration for optics and tactical accessories, giving operators full customization control.

Law enforcement trainers, military personnel, and civilian shooters benefit most from the P322's low-recoil platform for marksmanship development and ammunition-efficient skill drills. The threaded barrel is directly compatible with any standard 1/2x28 TPI .22 LR suppressor, making it an exceptional choice for shooters seeking hearing protection without permanent barrel modification. Its 7-inch overall length and lightweight profile make it suitable for duty-sized carry while maintaining full-sized ergonomics, and the modular design integrates seamlessly with existing duty gear and optic systems.
