I'm a lifelong member of the 1911 fan club. Got my first 1911 pistol (Ithica, stamped "U.S.Property") in about 1967. I am now 74 years old, and still carry a 1911 (Colt Officer Model .45) as matter of course. I was able to attend Gunsite in the summer of 1978, and learned from the Master Instructor, himself, Col. Jeff Cooper. .45 ACP has always been my pet caliber, and I don't think that will ever change.
