I agree with Red about the paddle being useful for prop and wardrobe. In between takes the armorer/prop guy will come around and gather up the guns from the actors. Decades ago I was watching a WW2 TV being filmed and when the scene was finished the armorer came around and took all of the 1911s out of the actor's holsters; the "1911s" were old Lytle aluminum castings ��. Paddles make things a lot easier on the set.
