I have been a gun enthusiast and collector for many years. My unbelievably lucky brother got the bug long after me, and he ran into a guy who had a very nice Remington-Rand 1911 he picked up for $75.
The guy's dad had brought it home from World War II and it had been sitting in a drawer ever since. Here is the kicker: The magazine was still full. I took it to the range and proceeded to empty the mag at a target at 50 feet. No glitches, no hic cups, no failures at all, and the mag had been compressed since 1945.
