How would I be able to find what plate I need to mount a Holosun 507c to a MP9 2.0 CORE? The Holosun is not listed in the manual. I'm new to RMR sights so be easy on me if this is a dumb question.
Im not familiar with your particular model but I would love to try and help. Does your slide already have the cut out in the slide?
