It strikes me as about right. The gun being nickel and P&R helps. I don't think $500 is a bargain, but not bad either. Anything under $400 buy it, and even at $400 I think its a good deal overall. 19-4s and 19-3s are very common. If the gun was say a 19 no dash, it would be a bargain. These little subtle things can greatly effect the value.
