Accessories for Sig

Sig pistols fall into two families in our range. The classic hammer fired P220, P225, P226, P227, P228 and P229, with competition versions such as the P226 X-Five and LDC, and the modular striker fired P320 and the compact P365. They take different sights and different routes to a red dot, so start by knowing which family your gun belongs to.

Sights

LPA makes adjustable sights for the P220 to P229 and the P320, for the P226 LDC and for the Sig 1911 .22 LR. For pistols that will carry a red dot, there are optics ready co-witness sets for the P220, P226, P229, P320 and P365, in fiber optic, blank, luminescent or white dots, including semi-adjustable versions and tritium night sights from Night Fision. At that height the irons stay usable inside the optic window. Choose in Sights for Sig.

A red dot on the P320

The P320 has the widest choice. Optics cut slides take plates from Outer Impact and 2BME for RMR, K-series, EPS, Acro, RTS, Docter and others, and some plates have a rear sight built in. P320 models with a removable rear sight plate get their own plates, so check which version you have. The Holosun SCS 320 sits in the cut with no plate. All plates are in Optics ready plates for Sig.

A red dot on the classic Sigs and the P365

On hammer fired Sigs without a cut, the dot rides on a mount pushed into the rear sight slot, in type A, B, C or S for different footprints, with separate mounts for the P226 X-Five, the P365 and the P320 with SP2022. Pick in Red dot mounts for Sig.

Grip and reload

Toni System makes 3D grips for the P226 and P226 X-Five, adhesive grips for the P320 Full Size and Compact, and base pads for the P226 family and the P320. They are in Grips for Sig and Base pads for Sig.

Frequently asked questions

Which P320 plate do I need?

First check whether your P320 has a removable rear sight plate, because those models take their own plates. Then choose by the footprint of your optic.

Do I need co-witness sights with a red dot?

Not necessarily, but standard sights are hidden by the optic. Co-witness sights let you aim through the window if the dot fails.

Do P226 parts fit the P229?

Some do, such as many sights and dovetail mounts. Grips and base pads are listed for specific models, so check each product page.
