YUP:

1) Traditions Deerhunter (1st ML) - could hang the gun from the trigger while cocked and it wouldn't fire. Had a gunsmith friend work over the sear and liked the gun after that. Friend bought same gun a couple years later and the whole thing was crap.

2) Lightning LD (1st inline) - pull 10lb+ from the factory. Adjusted it down and found out there was a fine line between reasonable pull and firing unexpectedly when the safety was flipped off. Led to a couple very bad surprises and I swore off every buying one again. Adjusted the trigger back to 10lb and sold it with full disclosure. It was accurate though.
