On the t.v. program Shooting USA, I have seen, this season, pro shooters with M&P pistols with both Aimpoint type optics, and Dr. Optic type sights mounted. Does anyone know who's making the mounts, where they can be purchased, etc? Anything you can tell me would be appreciated. My Para 1911 racegun is worn out, and I've got an idea to take the M&P to the races. Thank you very much. David
