*Make sure you know what slide cut you have before ordering. Read our P320 Fitment Guide to learn more.
This CHPWS filler plate will only fit Sig P320 models with a Romeo 1 Pro cut slide with RMR Holes and without rear dovetail sights attached to the slide. These are models usually made from 2020-Present.
This filler plate is designed for slides without rear dovetail sights like the M18, M17, and Legion models.
This filler plate provides more security to mounting an RMR footprint optic to your P320. That's because without it there is space in the front and rear of an RMR footprint optic, and there are no recoil lugs. This means all the recoil forces are going directly into the screws which could cause them to shear off.
This filler plate makes contact with the front and rear of the optics cut and provides recoil lugs. This gives you a stronger base to mount your RMR footprint optic.
