I am looking into getting a 1911, and I want to try and get an all purpose one so I am considering one with the rail mount on it for mounting my Surefire flashlight for home protection. So I have a few questions for you guys who own both a 1911 with rails and a regular one. How much wider do the rails make the gun, if any? Do you have problems fitting them in holsters, I understand that they probably won't fit at all in a molded polymer holster unless it is meant for rail guns, but what about leather concealment holsters and such. Especially the Galco Concealable leather holster, I really enjoy carrying in that one, or maybe someone's Summer Special IWB style holster. Thanks guys.
