Crimson Trace Red Dot Optic RDS RMSc footprint Listing ID: 3132291

this has never been used. It doesn't have a box with it because it was a freebie mounted to a Springfield Hellcat Pro. I took it off to put another optic on before I ever shot this. It is the RMSc footprint that fits on Sig 365's, S&M Shield Plus, Springfield hellcats, and Glock 43x (double check your gun optic footprint though - don't take my word for it because I could be wrong).
