I also had a troublesome Python. The cylinder gap was so tight that it would get lead buildup on the face of the cylinder and seize it. It probably wasn’t a junk gun, it just wasn’t tolerant to lead reloads. I ended up trading it for a new Colt combat commander.
To see Python gun-show prices skyrocket over the past 10 years, I always thought it was the premiere revolver to have. I'd heard they might have timing issues but never shot one let alone hold one.
My worst was a Jiminez semi-auto jam-o-matic I got years ago when I traded someting for it. Can't remember what I traded but obviously the other guy got the better end of that trade.
