No apologies needed. We must all remember that while some have had the same conversations and issue pop up thousands of times, others are new to the idea that some subjects have been LONG-argued. For example, I know some new folks to handgunning will ask "how do I pick between a 9mm or a .45?" and others will roll their eyes or go running away with their hair on fire, but it doesn't mean that
everyone has already seen or had the debate.
For me, I've bought and owned Smith & Wesson revolvers since I first began shooting over 25 years ago. I own MANY and though I do have a few double action revolvers that aren't S&W, S&W is what I love the most, by far, and it's not close. In all my years (not as many as some, but a significant volume of owning and shooting), I have only owned one S&W with the internal lock.
I found that it was a FINE revolver, incredibly accurate with a terrific feel of quality & workmanship. I had zero reservations about how well it would "work" in any situation but in the end, I had to move it out of my collection because it was a five-shot J-frame .357 Magnum and it was outrageously uncomfortable to shoot. In retrospect, I could have found a genuine place for it in my world if I had explored different aftermarket grips/stocks, but I never bothered to go that route because it seemed to be perfect for concealed carry but I had no intention of ever doing so, thus I let it find a new home.
When I shop for revolvers, Smith & Wesson specifically, I shop
used because that is (by FAR) where the deals are. So much value in a used revolver and the range of prices are almost without limits, where all NEW revolvers have similar prices. And when I shop for a used S&W revolver, I only ever shop pre-lock.
For me, it's not
because of the lock, it's simply because the lock shows me easily and from afar that it is a newer S&W revolver and I prefer older ones. I cut my teeth on revolvers from the 1980s, so I love those, and I have found great joy in revolver from the 70s as well. I am certain that I would love some from the 60s, and I have a few from the 90s that make me happy also. I typically don't care to shop for S&W any earlier than the 1960s nor later than the 1990s, but simply because I can find
so many in that span of roughly 40 years that I love so much for so many reasons.
Would I trust my life to a lock-equipped Smith & Wesson revolver made today?
Absolutely, without a doubt. Like any handgun I might put in that role, I would thoroughly test it to my satisfaction, and then I would go forth.
