I just picked up a 'New in the Box' 629-6 4" this morning, and took it out back to shoot it. Wow ... it's easier to handle than my 7+" Ruger Super Blackhawk Hunter, and is as accurate at 25 yds!

Does anyone have the variation index where I can see what 'dash' variants mean for this revolver?

Thanks

The book Standard Catalog of Smith & Wesson 3rd Edition has the information you seek.

The -6 was the second generation with MIM parts and the first with the lock.
