The present invention relates to a short recoil firearm (1) comprising a main body (2); a barrel (7) slidingly mounted on the main body (2) and a movable between a forward percussion position and a backward recoil position; a slider (17) slidingly mounted on the main body (2) and a movable between a forward position of closure of the barrel (7) and a backward stop position. The firearm (1) further comprises a plurality of cylindrical rollers (22) operatively connected to a spirally wound tape spring (26). The cylindrical rollers are movable between a first configuration, in which they lie mutually side by side between the slider (17) and the barrel (7), to prevent the relative movement thereof and to allow the integral displacement of same, and a second configuration, in which they lie in a recovery chamber (27).
