Joe, they are 1.75 inches on the throw... Im a little worried my throw is 1.55 but I think I will be able to make up that amount on the hammer... Have you ever seen a pistol grip trap style stock on any of the powells... I have yet to see one anywhere save the one I have and was wondering if they offered a trap model gun? Its really a shame that most all the records are lost on such a fine company.....
