I am not a LEO but had a question. I have done some stippling on a couple of my Glocks to improve the grips. I don't use the grip tape stuff or slip on grips. the grip tape comes off and leaves a sticky residue behing and the slip on grips are to pricy and are not what you really want most of the time. A friend of mine just joined the local sheriff dept, he saw the stippling job I did on my guns, used the 21 for a few mags and really liked it. He wanted me to do a stippling job on his duty weapon. I am not sure if that is legal or if I could get in trouble for doing that (destroying gov't property). So that is my question the the LEOs in this forum is it legal to modify your duty weapon and will the person that did it get in trouble? I know that you cannot modify a duty weapon in the army
