Another box down range yesterday and another hole in the web of my thumb. Not known as a fun shooter I realize, but would like to try a different grip. Anyone know of (installed) an optional grip for the model 444-KRH? I've looked around on-line, but not seeing any products specifically listed as a replacement. The stock rubber grip is OK... but not great. I wish it were a bit longer for a full pinky groove instead of the truncated design.
