Questions & Answers
Will this work with a Sig Sauer P320 X-Carry slide that has a Romero 1 footprint? Expert Answer

This C&H Precision Weapons adapter plate will only fit Dual-cut P320 model pistol (slides cut for the Romeo 1 Pro and RMR footprint). It is not compatible with slides that only have the Romeo 1 Pro optic cut. If you do not have a dual cut slide, you will need the C&H Precision Weapons SIG X-Series Romeo1 Pro Adapter Plate, which can be found by using the link below:

I have a Sig P320 M18 and I am trying to install a Holosun 507C optic on it, will this adapter plate work perfectly for this weapon and optic? Expert Answer

This C&H Precision optic adapter plate is for Sig P320 pattern pistols that do not lose their rear iron sight when the cover plate is removed. This means it will not be compatible with the P320 M18. The correct plate for your M18 that will allow you to install the Holosun 507C can be found by using the link below:

Helpful Negative Review
Very loose on slide. Poor QC? by TX, Verified Owner, February 26, 2023
I’ve used these plates in the past. The QC seems to have fallen off a cliff. Plate was loose enough where it would have served no purpose in mitigating recoil on the optic screws. I would not recommend this plate.

Fits great by Nat20SC, March 9, 2024
The plate is surprisingly light, and very thin. Can still easily cowitness with suppressor height sights. Plate length is short by a few 1/100ths of an inch at the front so it's not quite a perfect flush fit, but the optic doesn't move at all. Does w...

Perfect fit for P320 X5 Legion by RonR, Verified Owner, October 10, 2024
Used to mount a Holosun 507 Comp to a P320 X5 Legion. The filler plate fit perfectly! I did need to file the screw on the extractor side down by 1 turn, since it originally prevented inserting/removing the extractor.
