I will dance along the fence here. It is your gun, do with it what you please. Though, leaving the gun 'as is' does give it a certain character.
Along that line of thinking, a buddy recently returned a 1911 to a well known pistol smith for some sight work. The smith informed him that the staked front sight would be replaced and a dovetailed one installed. My buddy agreed but told him just to cold blue the area where the work was being done. Despite this, the smith did a beautiful refinish of the entire slide. My buddy was actually quite upset. All of the little dings and scratches were from genuine duty use of the pistol, hard earned and gave the gun character.
