i got a 6 inch stainless gp100 for fow fiddy 8 years ago
only reason it was so cheap was cause it came with nothing. no box, no manual, no original grips.
but it shoots great and the serial ends in the funny sex number, so im happy with it overall.
i think the 5 inch looks the best aestheically, but i wasnt gonna shell out close to double what i paid for a new 5 incher.
with the 6 inch full lug, even with full power magnum loads, theres hardly any muzzle flip, if any at all. all the recoil goes right into the palm of your hand, so if you dont like that, softer grips or a shorter barrel might be better.
was thinking of getting a blackhawk because the single action is calling to me, just debating wether or not to get the convertible one to shoot 9mm as a cheaper plinking round and saving the magnums for when i want a bigger kick.
