    The barrel in an HW45 doesn't sit parallel to the top strap.
    I have heard of a jig being used to cut a silencer thread at the correct angle, but the silencer looks wierd because it's not pointing flat.
    Extending the barrel will work, but again it will look odd.
    Also you might find that the rear sight runs out of adjustment because the extra weight of the silencer will dramatically alter the recoil characteristics.
