Agree. My husband is a firearms instructor, and he has two Taurus revolvers in his collection that he lets students use on the range. In one day, the transfer bars on both of them broke, and he had a heck of a time getting the new parts.
Here's one for you: a cylinder so badly fitted that after a half dozen shots or so, the cylinder expanded from the heat to the point the weapon completely bound up. Unusable except as a club.
