S&W 640 Pro

[ptgarcia]

if this is accurate, when did this begin? i have 6 S&W J-frame revolvers, but admittedly they are all no-dash pre-locks except the 640-1 pre-lock that i own.

thanks in advance for the info.

I want to say mid- to late-90s, but I'm not exactly sure.

i'll try to search for info at a later time. on a short online search, the only thing i've read since your post is that the 640-1 .357 Magnum/.38 Special does have a slightly longer cylinder than the .38 Special J-frame; what i read was not from specs given by S&W.
