I put a Burris Fastfire 3, 3moa, on a Ruger SR1911 with a Burris, made for a Kimber, mount plate. I like it better than open sights, but I only shoot it to 25 yards. My other 10 is a 1006, old police gun marked BPD91-0065. Leaving that one alone. Both guns like the Nosler 150 with 10 grains of AA#7, and the Underwood extreme penetrators are just wicked! Have fun shooting your new pistol!
