Bought a blued 6 " barreled GP-100 in 2003. Very nice gun, accurate, convinced me that I don't need a Smith and Wesson. My only complaint is that when I first shot it the rear sites were off, adjusted them. The forcing cone is of close tolerances to the cylinder, which is good, but I have to wipe the cylinder front down with Hoppes cleaner every 30-40 rounds or the gun will bind up. I used a fine file to cleanup the forcing cone somewhat.
If I was to get another one I would buy the stainless in a 4" barrel to be different. With the amount of shooting that I do with the GP-100, (200-250 rds of .38 specials and some .357 mag. a year) I cannot see how I would ever wear it out.
