Boot grips can be either combat (finger groove) or non combat. They generally fit flush to the bottom of the grip frame like the magnas do, to help hide the butt of the gun while concealed. They can be fitted to N, K/L, or J frames, but are most common on J frames.

There is a set of K frame combats for sale in the classifieds section here on the forum. In the items for sale forum.-
