Frame mounts for Glock 31

A frame mount adds weight forward of the trigger guard on the G31 rail, working against the rotation that causes muzzle rise after each shot. The G31 uses the G22 frame in .357 Sig -- an energetic calibre where forward weight is particularly effective at reducing per-shot muzzle rise. The G31 and G22 share the same frame rail, so frame mount compatibility is the same across both. Less rise per shot means faster sight return and tighter split times.

Confirm compatibility on the individual product page before ordering.
