I’ve got one Army surplus M1911 that’s tolerances so loose that it almost disassembles by itself. It still is a good shooter for self defense. While on active duty USAF I had to spend a week with a Marine gunny to qualify with the M1911 and in one week went from a fair shooter to an expert. I could disassemble the M1911 with a blindfold with pieces mixed up on a blanket in a minute. The weapon is my favorite and have more than one of them.
One was WWII vintage, manufactured by Remington Rand typewriter company in 1943. The other one I suppose was technically a "1991" - a Colt Commander.
