Automatic hand firearm

An automatic hand firearm comprising:

• a frame;
• a barrel mounted on the frame;
• a slide or bolt mounted on said frame rearwardly of said barrel for movement longitudinally with respect to said barrel, said slide having a bore formed therein in which a firing pin is movably located;
• a hammer pivotally mounted in said frame adapted to pivotally move to a position wherein it impacts against the firing pin;
• a spring member located in said frame having a portion acting against said hammer to continuously bias the latter toward the impacting position;
• a hammer pawl member pivotally mounted on said slide or bolt in overlying relationship to said hammer, said pawl member including means for engaging said hammer;
• means for biasing said pawl member in the direction of said hammer;
• and
• lever means for pivoting said hammer pawl member away from said hammer upon actuating a trigger member;
• whereby said spring member exerts a force on the bolt or slide through said hammer and hammer pawl member which tends to brake said slide or bolt when it moves rearwardly under a recoiling action and which retains the hammer in a cocked position prior to firing of the weapon.
