Ummm a Nice Model 19 probably shouldnt cost more than $500. And thats a real nice one. They are NOT that uncommon... at least in my neck of the woods. Last one I purchased has some holster wear on the barrel, and the cylinder $300. Ummm I dont know that the 19-3, or any other 19 was offered with diamond grips.
$800. for the Browning seems a tad high too... But if it's a nice one... Maybe.
