In one of the forums I frequent, a poster has offered up the old "Oh, these modern times suck! Ah for a return to times of yore, when the world was better!"
In this case, he was focussing on S&W revolver trigger pulls, claiming that all the new ones are wretched and things were so much better in the old days. Now, I currently have... let's see... over forty S&W revolvers, ranging in age from a .32 Double Action Third Model made in 1883 to a Model 431PD made in 2004. A couple of dozen more have passed through my collection over the years. I've been in the retail end of the gun business since 1993. I regard myself as qualified to offer a considered opinion on the topic of S&W wheelguns.
Here's the deal: The out-of-the-box trigger pull of a new Smith is about what it's been since I can recollect. (Which is to say "Unsatisfactory." No factory gun has a good trigger. If you think one does, you have low expectations.)
Marko and I were contemplating a new Model 520 when he commented "The trigger pull on this thing just doesn't compare to my old Model 10."
I replied that the new gun hadn't been dry-fired 50,000 times over the last 30 years, either, which will tend to have a certain smoothing effect on the action.
If you are lucky enough to run across an old S&W wheelgun that is truly "Unfired, In Box", see if you're allowed an experimental dry-fire or two. I think its trigger pull may be a little heavier and grittier than you'd expect.
