Mine fit perfectly on the sig m18 no filing required, dropped in fit.Solid piece came with screws.The rear sight is completely removed.if they made a built in rear sight notch would be great on the base however the price and quality is what I was after.Besides I have the Holosun 507c acss Vulcan reticle.This base fit perfectly I would highly recommend if you don’t t need the iron sights as backup.

The 507c mounted easily using this adapter with a Sig Sauer P320XFULL 9mm. The instructions were helpful if you have had experience with red dots.

Mount looks solid. The installation was simple once you're able to disassemble the slide, striker, and ejector spring. Just two screws in and out. The height over bore looks excessive, but I'll hold off until I zero the optic to see if that's actually a problem.

Install was intuitive and easy. Plate is rock solid. Mates up with slide and optic flawlessly. Holding zero so far after 400 rounds.
