Here is my humble pair of 1911s. The nickeled gun is an original M1911 dating to 1915. My great granddad came home with it after WWII and my dad inherited it when he was 15. It was pretty badly rusted, you can still see the pits, so he had it plated, fitted it with a gold cup barrel and bushing, did a ramp job so it'd feed semi-wad cutters and shot it in competition. I literally grew up with this gun and have been shooting it since I was 6. The Delta Elite is one I picked up fairly recently and has become my cold weather EDC. It is a late 80s one and the only work I've done was eliminating the series 80 safety. I agree that the 1911 is the most reliable of autoloader designs out there and that is why everyone has copied it to some extent. I've put thousands of rounds through mine and the only time I have had failures was once when I was a teen and learning to reload, I didn't resize the brass and had about 200 rounds that had issues. I change out the springs every thousand or so rounds and they both ready me right.
