I have a short track, 23 months, and no chart for the 2-1/2 Model 19. The average price is a bit higher than what's been posted so far. Here it is:
Smith & Wesson Model 19 Revolver in .357 Magnum,.38 Special, Plus P, 2.5 in Bbl, .38 Special, Plus P . Bluebook of Gun Values (31st Edition) indicates between $325 in 95% condition and $550 in 100% condition for this gun. I have 14 recorded prices for this model gun from $395 to $680 over a period of 1 Yrs 11 Mos ending January 10, 2011. The average price as of that date was $493. No refurbs, no refinishes, regular sights. All represented as 95% or better. No distinction for engineering revision, if any, no special editions, no distinctions for box, papers, tools. Current or last MSRP is $457.
