Anyone know if there is a modular adapter set that allows a Trijicon SRO sight to put on a Sig 320 that is already cut for an Sig RMR Optic sight? I have a new Trijicon SRO sight on my Glock 17 and it is a really good optic. I would like to put one on my Sig 320 which has an MRO on it now.

U have a Trijicon MRO on a pistol?

Which model of P320 do you have?

P320s that come from the factory with optic cuts are designed for the Sig Romeo 1. They will not work with a SRO.

However, you can get a P320 slide custom milled for a Trijicon RMR/SRO (they use the same mounting pattern). There are various gunsmiths that do custom RMR/SRO optic cuts on P320 slides.


Or, there are adapter plates available from Springer Precision for some P320s that will convert the Romeo 1 mount to allow for mounting a RMR/SRO, although with this setup the optic will sit a bit higher than a P320 slide with a dedicated RMR/SRO cut. And the specific adapter plate needed will depend on your exact P320 model.

If you have a M17, X-Compact, or X5 Legion, you'll need this plate: https://shop.springerprecision...RMR-Mount-SP0245.htm

If you have X5 or X-Carry, you'll need this plate: https://shop.springerprecision...ter-plate-SP0224.htm

Unfortunately, it doesn't look like they have adapters for RX or Pro models yet.

L&M Precision GunWorks will convert your SIG RX or X-FIVE from ROMEO1 to Trijicon RMR
