Adapter Plate Compatible with SIG P320 with Romeo 1 Pro Optic Ready Cut P211 GTO and Holosun 407C/507C/508T Trijicon RMR/SRO

This is essential for mounting an RMR on a Sig. 320 or GTO. It went on perfectly and caused the RMR to sit well centered and secure. Why spend more than double for a big name. DPP works very well.

Works great very snug fit on my optic and slide. so snug i almost didnt think it would fit, but it will. I had to use a little pressure pushing the pins that fit into the bottom of the optic. Sfter they poped in it was almost like the optic and plate were one peice. Be carefull removing the plate from the optic as the plate is really thing and looks like it would bend pretty easily. I put this on my Sig P211-GTO and keept the optic from shifting sideways. The little lip on the front filled the little gap from the slide and optic perfect. If you plan on using a rmr cut on the new sig loc footprint you need this plate

This is a very thin plate with 2 ears on the front, 2 recoil nubs on the top and 2 small oval ish nubs on the bottom. I have a Factory Sig pro cut slide, and I'm using a Holosun 407 red dot. It fits perfect, and comes with 4 screws for Holosun and 4 for Trijicon. I would say this plate will NOT fit all aftermarket cut slide unless it has a FACTORY Sig cut, long enough and cuts for the ears. I have an aftermarket GGP Sig slide, which is a nice slide, that has the RMR cut and correct holes. BUT It is a flat cut, its not long enough for this plate and nowhere for the ears and nubs on the bottom of the plate to fit flush on the cut. I got lucky with the plate I chose for GGP slide, it was aluminum with recoil nubs on the top only, I had to file the front ears and a bit of the plate to fit correctly.

Perfect fit for P211 and HD optic. Would be 5 stars but it won't let me click it.

Fits the P211 GTO

Fits perfectly on the p211 using an SRO. Sighted it in and went to a match with it last night. Noticeably better consistency with groupings as compared to when I had my Holosun 507C on with no plate. I will update this review should there be problems later down the road. But thus far I’m happy with the purchase.

Fit the Trijicon SRO to my Sig P211 perfectly. Tight tolerances, great titanium quality and still lets the optic sit low on the slide as intended. Great price for what is needed.

I was glad to be able to find an RDS adapter plate for my pistol, especially one at this price. It seems pretty sturdy so fa, and I was glad to have a few extra screws to replace the inevitable screw bouncing off the workbench into another dimension, never to be seen again. I can't speak yet as to the long term stability of the platform yet, but so far, it's doing it's job.
