I have not, but I've turned down lots of used S&W's that were sloppy. The most recent one was a 7-shot .357 mag Mountain Gun at a pawn show in Kernersville, NC. Way too much cylinder movement in every direction with the hammer lowered. As to S&W in general, it varies greatly by gun, and not necessarily because of use. My M38-2 and 625-6 do literally lock up like a vault, but none of my other Smiths do.
