If you never have to use it, there will never be an issue. If you do use it, there will be a ton of legal issues. The hardest to defend against are modifications that make a gun easier to shoot than the manufacturer intended. The term "hair trigger" sounds awful in a packed court room. Even something as simple as a trigger shoe can be artfully spun by a clever attorney into a weapon of mass destruction. Other than after-market grips, most departments forbid any modifications to issue weapons.
