Glock 31 Features

The Glock 31 is chambered in .357 SIG and offers all of the features of Glock's full-size lineup.  Identical in size to the Glock 22, its .40S&W brother, the Glock 31 provides everything a Glock has to offer, including a light and laser rail along the frame, Glock's Safe-Action trigger, a reversible magazine grip, and long 4.48" barrel.  Its cartridge provides similar energy to the .357 Magnum in comparable barrel lengths, and its long sight radius promotes user accuracy while its magazine capacity provides the user accuracy through volume.

Glock 31 Capacity

Available out of the box with standard capacities of 10 or 15 rounds, the Glock 31 chambered in .357SIG can accept larger Glock-made and aftermarket magazines that can fit in any of Glock’s full-size .357SIG or .40S&W pistols, allowing capacities of 22, 27, and 50 rounds.  This is all thanks to the .357SIG using .40S&W as a parent case, allowing magazine compatibility between the two calibers.
