Glock 31 Magazine - 10 Round

Factory Glock 31 Magazine

This is Glock's own 10-round magazine for the Glock 31 in .357 SIG, model MF10031. It suits shooters in states that limit magazine capacity to ten rounds, and owners who want a spare that is the same part shipped with the pistol. Glock also lists it for the compact Glock 32.

Features

• .357 SIG Chambering — The body is marked .357 at the top, so you can tell it apart from look-alike magazines in other calibers.
• 10-Round Capacity — It holds ten rounds and is factory blocked, which means it was built to stop at ten rather than reduced from a larger magazine.
• Capacity-Restricted States — The factory 10-round limit is intended for buyers in states that cap magazine capacity.
• Steel-Lined Polymer Body — A hardened steel insert sits inside the polymer shell, so the magazine keeps its shape and still feeds after it has been dropped.
• Numbered Witness Holes — The holes at the back, marked 4 through 10, show how many rounds are loaded at a glance.
• Polymer Base Pad — The flared black floorplate gives you a grip point for stripping the magazine and helps guide it into the magwell.
• Factory Original Equipment — It carries the Glock logo and the Austria marking, so it is the same magazine Glock supplies with its pistols.
• Black Finish — The plain matte black finish matches the factory frame.

Fit and Construction

The magazine is listed for the Glock 31 and Glock 32, generations 1 through 4. In the G32 it will stick out a little below the shorter compact grip. Construction follows Glock's usual pattern of a polymer shell around a steel insert, finished with a polymer base pad. The UPC is 764503100314 for anyone matching part numbers.
