For the life of me I have been unable to figure out how to effectively shoot a J frame. I have tried for years and had no success. I would really like to get another 642, but I cannot hit anything past belly gun ranges, and I know that they can be fired effectively at distance. I shoot K frames, L frames, autos, etc. and have no problems. I have been unable to pick up the skill set to shoot these smaller revolvers. What grip, etc. do you utilize to make the J frame perform for you?
