Well, to each his own...and I realize that other cosmetic alterations may only serve a cosmetic purpose, and no functional one, but this seems silly and unnecessary to me. I mean, TO ME, it doesn't even look good, and I can't see where it serves any functional purpose either. I guess if the only purpose is because the owner likes it, then it's sufficient. As others have noted, it's your gun...but should you decide to try to sell or trade it in the future, you may have really lowered the value.
