my only question would be: why go with such a heavy-framed revolver in such a potent cartridge only to get a 3" barrel? i've used a 4"-barreled gp-100 and think it's great.......but that seems a much more reasonable length giving some extra gusto to such a decent cartridge -- since the frame and grip are so heavy on these things.
if i wanted a 3" barrel in a .357 mag' i'd go with one of their 5-shooters whether for concealed carry or as a hunting back up piece. then again, i'd much rather have a 4 or 5" barrel with adjustable sights on it for hunting. incidentally, with a 3" barrel, i admit that the revolver is not much as a hunting back up.
the 4" i've used, with adjustable sights, does amazingly accurate shooting at 100 yds', let alone 50; probably because it handles recoil so well.
good shooting to you,
SS'
