Sig P320 to RMR Adapter Plate for Romeo 1 Pro Slides that don't have Rear Dovetails attached to the slide - CHPWS - SGX-RSH-GDT-ST

I gave this product 4 stars because I had a very difficult time to install it due to the plate fits extremely tight. I had to force it in by starting screws to hold it in place and then used rubber handle of my hammer to tap it in the cut-out spot on the slide. it's a super tight fit and at the end that's what we want! :)

Plate works as described allowing Holosun 507c to be mounted to P320. This adapter has built in dove tail for using iron sights as well. Freedom Gorilla has (by far) the most information available regarding installation and fitment. Thank you.

Very helpful and informative communication and responses to questions was always timely and courteous.

I purchased the SCS320 for my new P320 X5 Legion direct fit optic but the circle was smaller than I expected. I asked if I could return it and order another, no problem and fast hassle free return. I text and called and the guy's at Freedom Gorilla who walked me through what I was looking for and I ended up buying the 507C X2 GR ACSS. When I removed the plate cover on the gun I lost my rear sites because they are attached to the plate. They told me where the plates were located on the web site and the instructions walked me through every last detail. I found a CHPWS plate that has a dovetail milled into it and fits Romeo Pro1 Optic cut perfectly as well as the optic and new rear sight. The large circle and the "chevron", upside down V are awesome, you can use the circle to locate the chevron, put the tip of the inverted V on the target and bullseye. I like it so much that a week later I bought another to swap out the Crimson Trace red dot that came on my S&W 22 Victory Performance Center. It is a little bit large but I don't care it works great. Best Prices, Best Service, Best Guy's! You get it all at Freedom Gorilla. Give them a try and you won't regret it, and then tell all your friends and that next beer will be on them.

I bought the plate for my Sig P320 X Compact and it fits great. However I noticed that the dovetail for the rear sight says, "Glock Dovetail Only". To that end, the Sig X-ray sights I purchased to co-witness the optic won't fit. Frankly I'm surprised that a plate designed for a Sig pistol wouldn't also fit Sig sights. I called customer service and was told that the plate was made to fit aftermarket sights, not OEM Sig sights. They continued to say that most aftermarket sights are designed to fit Glocks, not Sig.
I found this explanation somewhat lame but do not buy this plate if you want to use OEM Sig sights.
