That looks great. I'm sure it's big improvement in grip. Have you tried carrying it concealed? Just curious if it was comfortable. I have yet to work up the nerve to try stippling an actual firearm, but I'm impressed by what you have done.
That is actually not my gun, it belongs to a friend so I haven't carried it. I did basically the same thing to the grips on my Beretta, and I have carried it. I don't think it is uncomfortable, but my tolerance might be higher than others because I have been putting grip tape on my guns and carrying them for quite a while. The only thing you have to watch out for is the material the cover garment is made out of. Certain types of fleece stick to the grips like velcro.
