Welcome. I don't know if I would mount the dot on the slide. Have you seen the straddle mounts that are popular on the 1911's? Or else, check into the Burris Fast Fire with a designated mount for the 52. It is supposed to be very shock resistant, and it is so small and light it should work well. I have one coming that I plan to put on a .22 bullseye gun first, then If I like it will see about one for a 1911. Glad to hear your still shooting at 77, I'm 68 and still at it and was wondering how much longer I can plan to shoot. Without the red dot I would have quit some time ago. Just wish I could get the darn cataract out of my right eye, Dr. says just isn't "ready" yet.
