I love the way Smith and Wesson only photograph the right hand side of their revolvers so as not to show that crap lock they insist on using. Note the pistols show the left hand side of the frame as no lock hole is present on the frame. They realize it is a negative yet they, or their lawyers, insist on placing a keyhole into the side of the frame for "safety" purposes. Tell that to the poor bastard who has the gun lock up on him while shooting a round of 454 Casull or 500 S&W at a charging brown bear. It's really a ridiculous concept.
I have not, nor will ever buy a revolver of theirs containing such a stupid and dangerous device. I'll stick with used, pre-lock era S&W revolvers, thank you very much. The Lemon Squeezer is the only current S&W revolver I would consider as they, thankfully, left the lock off of that one given its grip safety. Furthermore, I'm not sure how you have a reintroduction of prior "Classic" Smiths that now include a frame lock.....something that never existed originally.
