I have been looking for a Model 19 or a Model 28 at my local gun shows here in Tucson for the past couple of years. Today, as luck would have it, I managed to sell two pistols and a shotgun just before I ran into a fellow selling a Model 19-4 in very nice condition. A few moments of jaw-jackin' later and we had a deal. This is my first Smith & Wesson. I can hardly wait to shoot it. I would appreciate some help on manufacturing date. The Serial Number is E6 74935.
