Patent ID: 8316754

Claim:
Short recoil firearm, comprising: a main body ( 2 ); a barrel ( 7 ) comprising a tubular body ( 8 ) presenting a proximal opening ( 9 ) and a distal opening ( 10 ); said barrel ( 7 ) being slidingly mounted on the main body ( 2 ) and movable between a forward percussion position and a backward recoil position; a slider ( 17 ) slidingly mounted on the main body ( 2 ) and movable between a forward position of closure of the barrel ( 7 ) and a backward stop position; elastic means ( 26 ) working on the slider ( 17 ) to push said slider ( 17 ) towards the forward closure position; characterised in that it comprises a plurality of pushing elements ( 22 ) operatively connected to the elastic means ( 26 ) and movable between a first configuration, in which they lie mutually side by side along an operative direction (Y-Y) between the slider ( 17 ) and the barrel ( 7 ), to prevent the relative movement between said barrel ( 7 ) and said slider ( 17 ) and to allow the integral displacement of said barrel ( 7 ) with said slider ( 17 ), and a second configuration, in which they lie in a recovery chamber ( 27 ) placed on the side of said operative direction (Y-Y); wherein, during the passage from the first configuration towards the second configuration, the displacement of the barrel ( 7 ) opens an access ( 27 a ) for entrance of the pushing elements ( 22 ) into said recovery chamber ( 27 ), and wherein, during the passage from the second configuration towards the first configuration, the elastic means ( 26 ) force said pushing elements ( 22 ) towards said first configuration through said access ( 27 a ).
