Glock 10 Round Blue Magazine For Model 31 357 Sig - 357 Sig Caliber, 10 Rounds, OEM Origin, G31 Model

This is an OEM Glock Gen 4 magazine. Glock perfection. You can load 10 rounds of .357 SIG or 9 rounds of .40 S&W. Bear in mind that the difference between a Glock .357 SIg magazine and a .40 S&W magazine is the follower. Glock has two different magazines for a reason for .357 Sig and .40 S&W respectively. The follower on the .357 Sig is slightly taller to support the last few rounds in the magazine to ensure they do not bottlenose during feeding when the magazine is low on ammo.

Awesome.....so easy to load rounds compared to factory supplied mags.

Although it is grating to have to switch from the 15-round magazines that I carry here at home in Virginia to enter DC, these mags are not at fault, and did nothing wrong. They are classic Glock quality, are good-looking, and dead-nuts reliable. Buds had the lowest prices around, and fast and convenient shipping. A
