The simple fact is this is another revolver problem blamed on the lock without any evidence whatsoever. Doesn't even sound like a lock problem. The choir nod their heads and say "Amen" without a thought going through the gray matter that's supposed to be inside. Half of them have never looked in a S&W revolver anyway, and haven't a clue how the mechanism or the locks work. At one time there was a lengthy thread on supposed lock failures, most of them as convincing as this one. It's disappeared, hopefully into the trash. I don't like the lock. My three IL revolvers have modified flags, so the things aren't a concern. The mindless herd response to reported lock problems, however unlikely, just gets irritating. Rant over.
