A primer (10, 210, 310, 410, 510, 610) for firearms comprises a cap (11, 211, 311, 411, 511, 611) containing an explosive mixture (12, 212, 312, 412, 512, 612). In proximity of the peripheral edge of the bottom of the cap there is an element (13, 213, 313, 413, 513, 613) for radial reduction of the inner space of the cap intended to be filled with the mixture, to reduce the volume of the space available for the mixture by a selected amount. The mixture is advantageously free of heavy metals and can advantageously contain diazodinitrophenol. The presence of the element for the radial reduction of the inner space of the cap makes it possible to adjust characteristics of the mixture, thus improving the characteristics of the primer.
