I hate to ruin a perfectly good rant, but ALL revolvers without a transfer-bar safety are hereby grouped as unsafe, if you read the opinion. Do you feel that your S&W is unsafe? Maybe your Python?
Exactly what does safety-glass, seat-belts, and the rest of this tripe have to do with a gun? They are inherently unsafe in today's lexicon of safety. They are also dangerous. They have to be. There is no safe way to propel leaded projectiles, at high velocities, into other humans. SOMEBODY is going to get hurt.
Some imported revolvers are equipped with safeties. The American public has always regarded that as useless. The loading of five rounds in an SAA style pistol has been a tradition for more than a century. It's a matter of common sense, much like not driving down the road with your door open.
When supposedly intelligent people ignore safety rules, and get hurt, we today scream loudly that the manufacturers should have done something about it. The only thing not demanded is responsibility for one's actions. Can anyone imagine a revolver incorporating automotive safety standards in it? I'd rather not.
FYI, safety glass wasn't a mandated development. It was done just after WWII, about the same time that technology could provide curved, one-piece windshields. Seat belts were offered as options on cars as far back as the early 1950s. They weren't mandated until 1965, even though they became standard on many models in 1963-64. Automobiles aren't used in the same manner as firearms, so the safety standards applicable to them, no matter how snazzily they're offered, are the usual apples-vs.-oranges comparisons offered by the uninformed.
