RE: .Whats this worth???pistol...
Since you don't have the box you've lost some value.The Holster and box of cartridges add a little.Since your Smith has the 3T's I would say 300.00 would be a good price .According to a couple year old Gun Traders guide (has it as 265.00 value),the 2 1/2" and 6" barrel model 19's were discontinued in 1991. Someone looking for a 6" barreled model 19 might be willing to pay more since these are no longer available.
