I just bought a 629 classic with 6 1/2" barrel and power port. Beautiful gun, but I haven't had a chance to fire it yet. I imagine the rubber grips that came on it help with the recoil but I love the look of wooden grips. What I don't know is if my gun has a square or round butt. Don't want to remove the rubber grips just to see. Can Anyone help? Thanks in advance
