The P322 uses a fixed-barrel blowback system with an enclosed internal hammer and single-action-only operation. Its flat-faced trigger and rimfire-tuned action deliver a consistent, straightforward manual of arms in a lightweight package.
The slide is optics-ready with an RMSc/ROMEOZero footprint and features front and rear serrations for positive manipulation. Sighted with a green fiber-optic front and a fully adjustable rear (windage and elevation), it supports precise zeroing with or without a micro red dot installed.
An aluminum-alloy slide in Nitron black rides over a stainless-steel internal chassis and polymer grip module. An integral 4-slot 1913 accessory rail adds light/laser compatibility, and ambidextrous manual safety and ambidextrous slide catch levers support left- or right-handed use. The pistol is marked NEWINGTON, NH USA.
The 4 in threaded barrel pairs with the included SIG factory thread adapter for muzzle accessory compatibility. High on-board capacity (25+1) is complemented by six factory magazines in two capacities.
