An improved automatic pistol is provided with a lever mechanism which causes operation as a burst-firing arm in a safe and reliable manner. This is achieved by forming the disconnector, which releases the sear, with a chamfered and bent end, opposite to the end engaging said sear, in order to co-operate with a trigger bar which has two degrees of freedom in the usual repeating operation, and which is connected in an articulated manner to the pistol trigger. Through a 90°rotation of a selector member, a should on the trigger bar allows the trigger bar only one degree of freedom thus causing the disconnector, which is pivotedly mounted on the reciprocating breech mechanism, to enter into a tangential, instead of perpendicular contact through its bent and chamfered end with the trigger bar. Thus, the disconnector enables continuous firing of the pistol as long as the trigger remains is pressed. The breech mechanism is provided with a number of air intakes and is preferably of frusto-pyramidal shape for cooling the piston barrel.

An automatic pistol having repeat and burst firing modes of operation comprising: a pistol frame, a barrel carried by said frame, a slide carried by said frame for reciprocating movement between a pistol firing position and a recoil position, means for firing said pistol including a striker pin carried by said slide, a hammer and a sear carried by said frame, said sear being mounted for movement between a first position normally engaged with said hammer to prevent said hammer from striking said pin and a second position disengaged from said hammer for release thereof to enable said hammer to strike said pin, a trigger carried by said frame, a disconnector carried by said slide for reciprocating movement therewith and for movement between first and second positions, said disconnector in said second position being engageable with said sear enabling said sear to move into its second position thereby to release said hammer for firing said pistol, means carried by said trigger and responsive to a pull on said trigger to move said disconnector from said first position into said second position thereby enabling the pistol to be fired and, in response, said slide to be reciprocated from said firing position to said recoil position and back, said sear being movable into its first position upon movement of said slide from said firing position to again engage said hammer and prevent it from striking said pin for a second shot, means biasing said disconnector for movement into said first position, said disconnector lying in its first position under the action of said biasing means when, after firing, said slide returns to its firing position thereby preventing the pistol from firing until the trigger is once again pulled to move said disconnector into its second position, and a manually movable selector member carried by said frame for selecting a repeat firing or burst firing mode of operation for said pistol, said selector member, when moved to said burst firing mode of operation, being cooperable with said moving means for automatically moving said disconnector into said second position upon each return of said slide to its firing position thereby repeatedly moving said sear into its second position, releasing said hammer, and enabling burst firing of said pistol.
