I paid less for my 19-5, but that's in the range I've been seeing since I bought it back in the fall.
Mine also has a good, smoothed trigger, (I like a smooth trigger for DA shooting.) It came with rubber grips, which I also like, and has been accurate with my reloads and Black Hills 125 grain .357 Magnum loads.
I need to find a decent holster for my M19, but haven't yet.
Do you think they'd take $300 for it?
