When I do carry a 1911 it's a full size stainless delta elite in 10mm auto, Holster was made by Ian Martin, IHL (Ian's handgun leather later named International handgun leather). A prototype he gave me to try out an IWB (inside the waistband) bought it and still use it. Made of leather, strong side with Nylon rails built in, kind of like an upgraded old FBI and some Police OWB (outside the waistband) holsters except IWB with no snag rails and forward cant, beautiful holster. The final version of this holster I don't think he installed the rails. His holsters , belts and mag holders were sold by Dillon Precision, I think he is retired now if not mistaken, FYI his combat belts are the best I've seen double thickness leathers , beautifully made, strong buckles and fasteners, they don't roll over, very wide and stiff, made for heavier guns, these are not a dress holster and belt, basically flawless at a price. We have other 1911's and 1911-A1's in 45 acp and they are very good guns, a little heavy like the Delta. I cannot stress enough buy the very best Hosters and Belts, make sure they are comfortable and what you want, get opinions and reviews before laying down a few hundred bucks for really good leather. I don't especially care for plastics especially in belts. I do have a Kydex I sometimes use for a Sig P-365 for my every day carry IWB carry and it's surprisingly comfortable, a little noisy, normally with that gun I just use a good leather no print pocket holster.
