dehorning a pistol

[Meroh]

Chrome finish is very hard. So dehorning would be a challenge (if you want to preserve the chrome finish). Option 1: leave it as is (if your skin is tough enough and heals quickly)
Option 2: dehorn (if you are willing to live with a gun that doesn't look great as long as it shoots well)

Gently just buff only the sharp edges that have the potential to injure with fine 3-M roloc scotchbrite pads in a die grinder. You should be able to polish without cutting through the chrome.
