Rpg nailed it.
Bought one in Memphis, in the late 60's. Nice condition. Dry fired it once, and the firing pin shot out of the barrel, bounced of a door knob, and fell.
Had it replaced at York Arms, in Memphis. The replacement didn't last through the first box of 32's.
Sold it, after replacing the firing pin, again. I warned the purchaser of it's history, but he was a collector, and didn't plan on firing it.
