Glock Gen 4 Glock 31 357 Sig 10-round Factory Magazine

This is a factory 10-round magazine for the Gen 4 Glock 31, 32, and 33 pistols.
This is a full size magazine blocked by the Glock factory to be compliant in states that have a 10-round capacity limit.
While Glock pistols do an amazing job of taming the violent recoil that the 357 Sig has to offer, it’s the Glock factory magazine that ensures optimum feeding & reliability despite constant torture and even in the most extreme conditions …
Crafted from durable, crack-proof polymer and reinforced with full-length steel inserts, Glock factory mags feature numbered witness holes and a branded baseplate. Featuring a 10-round capacity, these full-sized magazines are compatible with all Glock pistols chambered in .357 Sig.
Fits Gen 3 and 4 Glock 31, 32 and 33.
Perfect for training or target practice, these 10-round factory magazines can take serious abuse and keep feeding reliably for years to come. Glock magazines come with a very strong spring rate from the factory to ensure reliability in the toughest of conditions. Sometimes, magazines are found to be a little bit difficult to load at first. However, after a few times loading and unloading, the springs break in nicely and it becomes much easier to load.
We recommend using a magazine loader to ease the loading process.
For added strength and durability factory Glock magazines are steel lined on the interior with a crack resistant polymer body. This increased durability gives officers, military members, and dedicated citizens the confidence that there will be no issues under heavy training.
