Pretty sure it was quality issues, just based on the problems I've had.
Tad, I hope you got a good one and enjoy it. Even if it is a good one you might want to replace the base pin with a hardened one from Belt Mountain. Their Colt SAA pin is an almost drop-in replacement. You just have to grind a *little* off the end to allow for the transfer bar. That fixed a lot of problems with mine, and the pins are pretty cheap.
OTOH if you only shoot .38 Specials, the soft original base pin might not cause any problems for ya.
