I have WW I and II vintage 1911's as well as commercial Colts, Star model P, Remington R1's etc. My most often shot 1911 is a Auto Ordnance GI model that is an almost exact clone of my 1943 Colt 1911A1 and I carry it in a reproduction of the shoulder holster that was made by Boyt in 1943 and is reserved for that same Colt 1911A1.
The pistol is totally reliable and handles like a 1911 is supposed to as well as being accurate.
