Hi, I've been browsing these boards for a couple weeks but haven't really posted yet. Anyways, I just turned 21 and decided I probably want a .357. I've narrowed down my search to a S&W 686, Taurus Tracker 627 and Ruger GP100. I think I'll get a 4"-6" barrell. Looking around locally, I think I could get anyone of these for $400 or less. Could you please help a revolver newbie out and let me know your thoughts on these three guns. I'd like to throw the Coly Python in there too, but the price is a little steep. I did see a Colt King Cobra (I think thats what it was), so please tell me any thoughts about that one too. Thanks in advance.
