Is dehorning something that should be left to a gunsmith? I really only need two spots on my R1 buffed out a little so that I can carry in comfort. I obviously wouldn't want to ruin the finish of my pistol, but if this is a job I can tackle myself without doing so I'd like to know. I'm looking online for info but any advice I get here is always appreciated. I've circled the problem area (same spot on both sides) in this pic.
