Glock 31 Gen 4

The GLOCK 31 Gen4, in 357 SIG, is the optimal solution for those seeking high muzzle velocity and superior precision in a reliable, yet lightweight, pistol with large magazine capacity.

Like all Gen 4 versions the G 30 comes with two additional back straps, medium and large. With no additional back straps fitted, the grip size is small. A rough textured finish on the frame gives you that added traction and the dual recoil spring spring assembly definitely smooths out that recoil.
