FWIW, I do not have any S&W revolvers with the built-in safety lock because I find them unsightly. If someone "gave* me one, I would not remove this safety feature for this reason:

I was a big fan of S&W revolvers back in the pre-lock days but I gravitated to 9 mm semi-autos. As I get older with more issues in racking slides, etc. I'm looking at going back to revolvers. Just looking for opinions from those who should know as to the quality of the newer S&W revolvers. One of my target guns would be a 686 Plus. (I think I can live with that big hole in the side of the gun now or as we used to call it "the infernal lock".)
I'm feeling a desire to get back into revolvers, even if I have zero need for one!
