I guess times are changing. For the last decade and a half, my duty gun has been a Glock 22. Recently my agency has switched to a Glock 17 with a Trijicon RMR and co witness irons. My training gun for a long time has been a Ruger Mark iii. Good gun made even better with the slingshot mod and disabling the magazine disconnect safety. Just ordered a Vortex Venom and a Burris Fastfire base to slide into the rear sight dovetail. Anyone here have experience installing an optic base into a dovetail?
