Accessories for Glock 31

The Glock 31 is the full size Glock in .357, a fast, bottlenecked round with a sharp recoil. Its frame and slide share dimensions with the 17 and 22, so the parts on this page come from that range and list the 31 among the models they fit.

Weight and grip

A sharp round benefits from weight up front. Toni System frame mounts add it under the barrel, and aluminium base pads add it at the bottom of the magazine. Find them in Frame mounts for Glock 31 and Base pads for Glock 31.

Sights

The 31 is often carried, and tritium sets suit that use. For the range, fiber optic and adjustable LPA sets are in Sights for Glock 31 too.

Red dot

Where the slide has a MOS cut, Optics ready plates for Glock 31 lists the plates by optic. Older slides keep their original shape and carry the dot in the rear dovetail; see Red dot mounts for Glock 31.
