Egw model 49518 mount for sig p320 standard full size frame - Evolution Gun Works Trijicon RMR Sight Mount

Purchased the EGW Model 49518 mount that replaces the dovetail sight on the Sig P320 Full Size Frame. I used this mount to replace the standard dovetail rear sight with a Holosun HS507C-X2 red dot system. The manufacture installation video recommends starting the new mount process from the left side of the slide. I had my local gunsmith Downhams & Sons shooting supplies remove the original sight and install the new mount with their sight pusher tools. The gunsmith stated that the mount inserted from the left side per manufacture recommendations was straight forward without any modifications needed. Everything was snug and tight as needed for the application. This application of mount and red dot did not effect the operation on slide during my zeroing of sight with three ammo brands.
