Most Helpful Negative Review Very loose on slide. Poor QC?
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.

Perfect fit for P320 X5 Legion

by RonR, Verified Owner from CA, United States Written on 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.

Fits great

by Nat20SC, from OR, United States Written on 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 what it says on the tin
