About the Glock 31

The Glock 31 is Glock's full size .357 SIG: a 4.49 inch barrel and a 15 round standard magazine. It is the same size as the Glock 17 and Glock 22, so holsters are often listed for them together.

Magazines from the Glock 22, Glock 24 and Glock 35 fit it too: they take the same magazine, and theirs are as long or longer. Glock's .40 S&W and .357 SIG magazines are the same. Shop .357 SIG ammo.

We have 467 in-stock accessories made for the G31, from Glock and other makers: 30 magazines, 16 holsters, 11 grip modules & frames, 1 barrel and 25 optic plates. They ship to your door where your state allows.
