Sig Sauer P322 22 LR 10-Round Magazine - Black Polymer (Model 8900744)

The Sig Sauer P322 22 LR 10-round magazine is the factory standard feed system for Sig's popular P322 rimfire pistol. Built from black polymer, this magazine holds 10 rounds of .22 LR ammunition and incorporates a loading assist feature that makes filling the mag quicker and easier, especially useful during extended range sessions or practice drills where you're swapping magazines frequently.

The loading assist works by letting you pull down slightly on the loading tabs to relieve tension on the magazine follower, creating just enough space to seat each round cleanly. This design helps ensure rounds stack properly and feed reliably through your pistol, rather than binding or jamming during loading. If you shoot .22 LR pistols regularly—whether for plinking, small-game hunting, or general marksmanship practice—having spare factory magazines means you spend more time shooting and less time reloading a single mag.

This is an OEM Sig Sauer part, so it's engineered to work seamlessly with the P322 platform. Black polymer construction keeps weight minimal and durability high, and the straightforward design means there's nothing complicated to maintain or troubleshoot. Stock up on a few so you're never caught short at the range or in the field.
