It's your gun. I say do with it what you want. But, you have to realize laser engraving the stock will drastically hurt the value of the gun down the road which most all here have suggested. Likely though, a gun given from Grandfather to Grandson will stay in the family, so value might not even matter. I do like the idea of engraving the grip cap, but again it's your gun.
