Alright, i just got this gun and it looks and shoots better than any gun i've ever held or shot. It's a S&W model 29-4 with a serial #BBY-****. What i want to know is what's the difference between it and the 29-3 and 29-5, and is there a purpose behind the smoothed out cylinder. Don't get me wrong, the more i look at it the more i love it, but im' just curious. And of course being the proud new owner i just wanted to show it off. :D :D :D

oh yeah, lol...don't mind the confederate beer can in the background, it was the closest thing i could find to prop the gun up against.
