I grew up shooting a .45 ACP, so 85% of my carrying days were with a Mk IV Series 70 or a Springfield Armory NM M1911A1. The remainder of my carrying time was about evenly distributed among a Ruger Police Service Six, a Firestar .40 S&W, and a Taurus M431 .44 Special. I still have the Ruger and sorely miss the other two.
My holster is a Milt Sparks Yaqui Slide for carry when concealment doesn't really matter, and a Milt Sparks Summer Special for when concealment DOES matter.
Since I'm past the half-century mark, I'm finding the virtues of alloy frames more appealing. I'm shopping about for a Commander-size 1911 with a frame that makes it weigh in under 28 ounces empty.
Suggestions would be gratefully received.
