Optics ready plates for Sig

The Sig P320 and P365 are striker-fired modular platforms with factory optics cuts. The P320 is Sig's full-size competition pistol, widely used in Production and Open; the P365 is the compact variant. Both use standard plates sized for their respective cuts.

A slide-mounted red dot lets you aim with both eyes open and pick up the aiming point faster than iron sights, then hold it through recoil — which is why most competitors move to one. The plate is the part that makes it work: it bridges the Sig's mounting interface to the footprint of your chosen optic and keeps it sitting low and rigid over the bore.

Two dimensions have to line up — the cut or rail on the Sig and the footprint of the optic you intend to run. A few plates include an integrated rear sight to preserve a co-witness backup. Check both against your setup on the individual product page before ordering.
