Description
When your P322 came with 20-round magazines, you might not have thought you'd ever need a 10-rounder. But there are plenty of good reasons to keep a few of these in the bag. Whether you're running structured drills, working with a new shooter, or just prefer shorter strings of fire during a range session, the 10-round format keeps things deliberate and focused.
This is a 100% genuine OEM magazine straight from Sig Sauer, not an aftermarket copy. The body is built from glass-reinforced polymer, which gives it solid shock and impact resistance without adding bulk or weight. Inside, a steel wire spring and injection-molded anti-tilt polymer follower work together to feed rounds cleanly and keep the stack aligned from the first round to the last.
One of the standout features on this mag is the loading-assist system. Just pull down slightly on the side loading tabs and the follower tension backs off enough to drop rounds in one at a time without a fight. It's a small thing, but if you've ever wrestled with a stiff rimfire magazine, you'll appreciate it immediately. Those same tabs also double as a round-count indicator, so you can do a quick visual check on how much ammo you have left without dropping the mag.
This magazine ships as a single unit and is designed exclusively for the Sig Sauer P322 pistol in .22 LR. It won't fit any other platform, so make sure you're ordering for the right gun. Grab a couple for your range bag and you'll always have a fresh one ready to go.

Frequently Asked Questions
Will this magazine work with any other pistol besides the P322?
No, this magazine is designed exclusively for the Sig Sauer P322 pistol. The P322 uses a unique rimfire magazine format that is not shared with other Sig Sauer handguns, so it won't fit or function correctly in any other platform.
What's the point of getting a 10-round mag when the P322 already comes with 20-rounders?
There are a few solid reasons. Some folks prefer shorter strings of fire for structured drills or new shooter training, where managing 10 rounds at a time keeps things more controlled. The 10-round format can also be handy for competitions or range settings where round counts are limited. Having a couple of spares in any capacity is always a good idea.
How does the loading-assist feature work?
The tabs on the side of the magazine can be pulled down slightly to relieve tension on the follower, which makes it much easier to press rounds in one at a time. Loading one round at a time also helps ensure proper alignment inside the magazine, which contributes to reliable feeding. It's a practical feature that makes a noticeable difference with a full 10-round load.
Is this a genuine Sig Sauer magazine or a third-party product?
This is a genuine OEM factory magazine made by Sig Sauer to the same specifications as what ships with the pistol. It's not an aftermarket or clone product. Sticking with factory magazines is the best way to ensure reliable function and a proper fit in your firearm.
What material is the magazine made from?
The body is constructed from glass-reinforced polymer, which provides excellent resistance to impact, shock, and corrosion. The follower is also polymer with an anti-tilt design, and the internal spring is steel wire. The combination keeps the magazine lightweight while still being durable enough for regular range use.
