SIG Sauer P322 .22 LR 20+1 Semi-Auto Pistol – Optic-Ready, Threaded Barrel, Fully Ambidextrous Controls
SIG Sauer’s P322 delivers rimfire capacity and modern features seldom found in a .22 LR pistol. Released in March 2022 as SIG’s first high-capacity rimfire, this polymer-framed handgun pairs a 20+1 round count with an optic-ready slide, enclosed-hammer single-action trigger, and factory-threaded 4-inch barrel. The result is a versatile trainer or suppressor host that mirrors the handling of today’s leading defensive pistols while keeping range time affordable.

The P322’s optic-ready slide accepts Shield RMS or SIG ROMEOZero-pattern micro-red-dots, allowing shooters to mount a reflex sight without gunsmithing. Front and rear serrations provide sure manipulation, and the factory fiber-optic sights remain co-witnessed when most optics are installed.
A threaded carbon-steel barrel (1/2x28 adapter included) lets owners attach rimfire suppressors or other muzzle devices. Its enclosed hammer ignition system maintains reliable rimfire primer strikes while delivering a consistent, flat-faced trigger pull. An additional curved shoe ships in the case for those who prefer a traditional feel.
Completely ambidextrous controls—manual thumb safety, slide catch, and a reversible magazine release—make the P322 equally convenient for left- and right-handed shooters. A three-slot Picatinny rail on the dust cover supports lights or lasers, extending the pistol’s versatility for training or small-game pursuits.
The stainless-steel receiver and hard-coat-anodized slide combine durability with a subdued black finish that matches the polymer frame. Serial prefix 73A confirms factory-matched slide and frame.
