When you said you shot a group at 15m, I knew you weren't from around here, aye? We shoot at 15 yards. I own a GP-100 4". It's my woods gun. It's not quite as accurate as my 686, the trigger is not as smooth, but it will shoot the hottest 357 loads all day long. "Chunky" is a great adjective for the GP-100. It's a poor man's Smith. Ruger makes the only other DA revolver I would recommend besides Smith and Wesson.
