I have Sam's saddle holster for my 1911. I bought it mainly for range work with a matching mag pouch. It's an excellent holster that I'll have for years. I too would like to try his McDaniels IWB for me Kahr and I like the fact that you can get different straps so you can use it on different belts from time to time.
I've also drooled over the Max Con IV. If I ever get my micro .45 1911, I'm thinking that'll be the right holster.
Good luck in your search!
