Abstract
A dual action retention pawl for securing ammunition in a breech loading gun having a bore along a longitudinal axis of a barrel of the gun and a breech opening with a moveable breech block at a rear of the bore. The dual action retention pawl includes a base, a pawl arm, and an activation arm operably attached to the base. The pawl arm pivots to a retracted position in response to ammunition engaging the activation arm when the ammunition is loaded into the breech opening and returns to a retention position once the ammunition is loaded to retain the ammunition within the barrel of the gun. The pawl arm pivots to the retracted position in response to the breech block engaging the activation arm when the breech block is moved to close the breech opening.
