Accessories for Sig P320

The P320 is Sig's modular striker fired pistol, built around a removable fire control unit that moves between grip modules, and the basis of the US Army M17. It has the biggest range of parts in our Sig catalogue.

Optics

Plates from 2BME, Outer Impact, Toni System and Night Fision cover RMR, K-series, EPS, Acro and multi footprint optics. Some fit P320 slides with a removable rear sight and some the others, so check the plate title. The Holosun SCS 320 fits the cut with no plate. Older P320 slides without the cut are served by mounts that take the rear sight's place.

Sights

Adjustable LPA sets suit a classic slide; the optics ready slide calls for co-witness height sets, available in tritium, fiber and plain versions.

Grip and magazine

Toni System adhesive grips for the Full Size and Compact modules, and an aluminium base pad.
