[The dangerousness of revolvers cal 4 mm, long (author's transl)].

Abstract

Different models of revolvers (cal 4mm, long), which are obtainable without special permission in Germany, were examinated as to their dangerousness. Both measurements of the kinetic energy of the missiles and investigations on cadavers were performed. Firing of the weapon in its original state yielded kinetic energies of the missiles well below the legal limit of 7,5 Joule. However, even then, fatal injuries of lung and heart could be demonstrated (In one case the os temporale was penetrated). Alteration of the revolver by closing the gas pressure releasing channels with expoxy resin yielded an increase by 45% of the kinetic energy of the missiles. If, in addition, the propelling charge of the ammunition was augmented with some more gun powder the kinetic energy of the missiles rose by 220 %, while such altered ammunition alone caused an increase of 75 %. In every case fatal injuries on head and thorax could be produced. Based on the results of this investigation proposals to amend the existing laws were made.
