Looking for info from those who own a Charter Arms Bulldog 44 Spl. My father-in-law just gave my wife his Bulldog. It has a 3 in barrel and the push rod for empty casings is exposed not enclosed. Also it has a (not sure what to call it) concealed hammer? It is a double action but she can't pull back the partially hidden hammer. Anyone know where I could find information on this pistol? Thanks.
