Re: holster for 1911 w light
I have a very nice belt holster with thumbsnap from Erik Little at Rafter L Gunleather for my Colt 1911 with Dawson rail. He told me after he made mine that he was probably not going to make any more for Dawson rail guns, due to not having a pattern gun to use when boning the leather. He may have a pattern gun for other guns, you might want to look on his website and give him a call. His leather work is absolutely on a par with the best I have seen, and he is very good about responding to questions.
Mark Garrity at Garrity's Gunleather might be another source. I am waiting for a holster, mag pouch and belt from Mark. He will probably make you a holster for anything he can find a pattern for. I haven't had an opportunity to handle any of Mark's products yet, but he gets very good reviews on 1911 Forums.
You will have to wait a while to get anything from either of these guys, because they are both very busy, but I think the quality will be worth it to you.
