Sig Sauer P322 .22LR Pistol - 4" Barrel, Fiber Optic Sights, Black Finish
The Sig Sauer P322 .22LR pistol is a purpose-built rimfire option for shooters who want serious features in a compact, lightweight platform. Built entirely by Sig Sauer in New Hampshire, the P322 brings the company's engineering DNA to the .22LR market with a thoughtful blend of everyday shootability and modern optics integration. At just 17.1 ounces with a 4-inch barrel, it's nimble enough for plinking and training, yet refined enough to reward precision shooting at distance.
What sets the P322 apart is its optic-ready design. The removable rear sight plate accepts a ROMEOZero red dot without adapters, letting you go from irons to glass in seconds. The threaded barrel comes from the factory with an adapter, so you're suppressor-ready out of the box—a genuine advantage for shooters building a versatile .22 pistol. Ambidextrous controls and a reversible magazine catch make it equally comfortable in either hand, while the included flat and curved trigger shoes let you dial in your preferred break. Fiber optic front and rear sights deliver bright, fast sight pictures for quick target acquisition, and the 6-inch sight radius keeps groups tight at typical handgun distances.
The P322 ships with two 10-round magazines, a magazine loader, and the threaded barrel adapter—you get what you need to start shooting. The stainless steel and polymer frame keeps weight minimal, the M1913 accessory rail opens door for lights or lasers, and the manual safety provides an extra layer of control. This is a practical, well-thought-out .22 for anyone from competitive shooters to casual rangegoers who refuse to compromise on features.
