I love Ruger revolvers but I swear the monkey on the line tasked with thread-locking their cylinder release screw must sleep through much of their shift. The only consistent issue I've ever had with Rugers is that flipping screw backing out seemingly due to no/not enough goop on the darn thing. Years ago I just started automatically pulling them from new guns and slathering them up good, none have backed out since, but geez
