So what would be the best way to trim the hand guard on my Pro? I'm loading deuces and need to slim down the bottom of the hand guard. Dremel or just just use sandpaper?
Do you mean the plastic forearm on a JM Pro? I used a coarse file to get it shaped the way I wanted it, then finished with sandpaper ending with 1000 or 2000 grit on my Vinci. It turned out great and looks factory.
