Glock 31 Magazine

Factory Glock 31 Magazine

This is the factory-original 15-round magazine for the Glock 31, chambered in .357 SIG, a bottlenecked pistol cartridge. OEM means it comes from Glock itself, the same magazine the pistol ships with. It suits owners who want spares for carry, duty or range use without the fit and feeding questions that come with aftermarket magazines.

Features

• 15-Round Capacity — Holds fifteen rounds of .357 SIG, the standard full-size capacity for the Glock 31.
• Factory Glock OEM — Made by Glock to the same specification as the magazines supplied with the pistol, model number MF31015.
• Polymer Body With Steel Insert — A full-length steel liner sits inside the polymer shell, so the feed lips and body keep their shape under spring pressure and repeated drops.
• Anti-Tilt Follower — The polymer follower, the platform that pushes rounds upward, is shaped to stay level so the last rounds do not tip nose-down and stall.
• Numbered Round Indicators — Numbered holes on the rear of the body let you check how many rounds are loaded at a glance.
• Ambidextrous Catch Cutouts — Notches on both sides of the body work with left- or right-side magazine release setups.
• Removable Floor Plate — The flared base plate gives a solid surface for seating the magazine and comes off for cleaning.
• Black Finish — A plain matte black finish matches the pistol frame.

Fit And Compatibility

The magazine is built for the full-size Glock 31 and also works in the compact Glock 32 and subcompact Glock 33, which take the same .357 SIG magazines. In those shorter pistols it extends below the grip, giving extra capacity for a reload. Because it is factory Glock, it fits standard Glock magazine pouches and holders made for this size.
