MAG SIG P211 9MM 23RD

Description

The Sig Sauer P211 factory magazine is built for competitors and serious defensive shooters who need a full 23-round payload without relying on aftermarket components or extension kits. This is the OEM magazine Sig ships with the P211 platform, so fit and function are dialed in from the factory rather than adapted after the fact.

The body is steel, which keeps the feed lips consistent under the mechanical stress of repeated loading and chamber cycling. Where a polymer tube can flex slightly under a full load, steel holds its geometry, and that matters most at round counts where a follower is working against maximum spring compression. Speaking of the follower, it runs an anti-tilt design that keeps each cartridge properly oriented against the steel feed lips as the stack rides up — reducing the angle-related misfeeds that can occur when a follower cants under spring pressure.

Rear-facing witness holes let you read remaining capacity without removing the magazine from the pistol. That is a practical advantage at a competition stage or during a training drill where a visual check needs to be fast and unambiguous. The aluminum baseplate with polymer sleeve seats flush and locks positively to the P211 grip module, which matters if you are dropping and retrieving magazines under time pressure. No rattle, no play, and the aluminum keeps weight at the base where it marginally aids the magazine’s drop-free behavior.

This magazine also fits the P320 Full and Carry configurations in 9mm, making it a dual-platform option if your collection spans both pistols.
