Is it a Remington or Colt? Is it an Armory rebuild?
I have a '45 Remington. Got it from my daughter's former boyfriend. He bought it from a WWII vet who owned. I have shot it a few times, but no more. Remington had better heat treating than Colt. So its unlikely the frame will develop a crack at the slide lock.
The top two are both Remington Rands, all correct/original. The third one is a licensed Colt for the Argentine Army (aka 'Sistema'). It's original except the grips but Parkerized instead of the original bluing. the top and bottom ones, I have stripped and then baked oil into the Parkerizing for protection; I haven't done the '45 (middle) one yet, so it will be darker and more handsome in a week or so when I get it stripped, cleaned, lubed and heated.
The '44 has a good/bad story. The guy I bought it from had gotten it from his buddy in graduate school. The buddy was an ex-Green Beret officer and out of the Army, and back from Nam and going to grad school at U of Alaska. He died in a car wreck while in school in '68. His family gave it to the guy I bought it from two years ago, so he had it from 1968 to 2020. I don't know if it was in the war, it might have just been a DCM gun. Shame about the Green Beret. He got through Vietnam and then dies in a car crash his first year home.
I've had a lot of 1911s over the years, from a stock Norinco to a full custom from Wayne Novak. I've built a few myself from Caspian parts and was tutored a bit from two really good gunsmiths. I may build a MEU(SOC) clone this winter or more likely next year.
