SIG 320 M17 RMR MOUNT W/INTEGRATED REAR SIGHT

For the Sig 320 application, a front sight with a nominal height of 0.375" is recommended. You can run front sights anywhere from .365"-.400" and they will be fine. We recommend either a Trijicon or Dawson Precision front sight. This permits the iron sights to be utilized independently of the optic if necessary.

Below is a photo depicting the slide configurations that this plate will fit. Compare the slides shown with yours after the factory

plate is removed. The striker assembly has to be removed to access the fasteners in both configurations. 

All plates come with the LCI notch as it works perfectly with both configurations of the pistol. If you choose to not run the LCI mechanism, but have the cutout on the slide's breech, the notched plate will work just fine. Concerned about blowback (GSR) on your optic? Don't be. As we say, you're shooting a handgun and there will be GSR everywhere no matter what. The optic may require a brief wipe down after an extended shooting session. This is normal under any application of a slide mounted optic.
