So the first 1911 I got had a beavertail safety. So I learned to shoot it with a very high grip. Recently I acquired a early (1918) Colt Gov't Model. I'd like to shoot it more often (its a shooter grade, Augusta Arsenal rework), but every time I do it bites the heck out of my hand. In fact, I had to stop my range trip early last time to go and wash the blood off of the rear of the gun. Considering I don't want to swap out parts, how can I adjust my grip to not bite my hand? How do those of you who shoot both kinds of grip safetied 1911's adjust to keep from getting bitten?
