If you hate to spend more time reloading than shooting, stock up on at least a few extra magazines for your GLOCK before you head to the range. This is a genuine factory GLOCK 31 magazine for the .357 Sig and is designed to work in all previous versions of the GLOCK 31, as well as the Gen4.
Each magazine is constructed from a steel insert encased in polymer for high durability. These magazines drop free from the gun when the release button is pushed, allowing for a quick and smooth reload with your next magazine. This magazine features a double-cut body and will work if you have reversed your magazine release on your Gen4 GLOCK 31.
