Welcome to the big boys' club.

You are living proof of what that old soft drink commercial used to say: "Try it. You'll like it." I still have my first .45 pistol, and it's 100% GI all the way through. When I got it long ago it was an Army mixture of 1911 and 1911-A1 parts on a Colt frame made back in the 1920s. I still like the long steel 1911 trigger and the old checkered wide spur hammer that I think is 1911 vintage, too. Mine has the arched A1 mainspring housing, but I can take it or leave it. I still like the lanyard ring on the butt, too. Other than having the barrel throated a bit and the feed ramp well polished (by yours truly), it's strictly stock from the Army arsenals. The slide assembly when I got it was WWI or 1920s vintage and was pretty loose. I wouldn't do it now on account of any possible collector value, but long ago when I didn't know any better I swapped it out for a WWII or Korean War vintage unissued slide that fit very nicely, still was loose enough to be utterly reliable, and had somewhat improved sights on it. I want my .45s to be able to hit my mailbox at fifty feet, but loose enough to rattle some when I shake them. I'm not deer hunting with them or shooting steel plates at a hundred yards, so rattles don't bother me at all. I guess that makes me "old school" but that's OK. I've still got the first manila envelope target I shot when I got that pistol (the first .45 I'd even held at the time) and it's not too shabby. That pistol stays right beside my bed every single night of my life now, too. I've got a couple of nice Colt Series 70s, but that old GI pistol's got mojo!
