Got you bracketed, I purchased a nickel 2 1/2" 19-5 for $400 and a blued 19-2 4" with original diamond rosewood targets for $450 in the last 60 days. Yes, I was lucky on both...
My NIB 19-3 Nickel with box,tools and docs was priced at $650. Due to the trade I made I'm in it at about $550.
I have a 2.5 inch M19-3, blued, with fairly substantial holster wear, but tight and functions well. Any idea what it would be worth? Serial number seems to be: 45951. ABove that it is just stamped MOD. 19-3
