I was at the range yesterday focusing on felt recoil of the Buffalo Bore 20B/20 (125g .38 Special +p) versus other ammunition I had on hand. Since the specs show terminal performance approaching .357mag levels, I had a couple types of .357mags with me. I went back and forth between the five different types of rounds testing the felt recoil.
The point of this was that I shot quite a few .357s and had my Crimson Trace LG-308 Lasergrips on the gun. Never turned on the laser; it wasn't the focus of the day. In my normal grip, the laser bump rests just above my right index finger. After a number of cylinders of .357s, this protrusion tore off the top layer of skin on my finger. It doesn't happen with .38s of any flavor, but those full house .357s got to be painful.
My lesson learned is that if I intend to shoot a fair amount of .357s, I will use my Hogue Monogrips instead. If I want to practice with the lasergrips, I'll restrict myself to (mostly) .38s.
