" " The machine-pistol is provided with an obturator which extends longitudinally, so to surround with a cylindrical or semicylindrical portion, in its putforward shooting position, a longitudinal length of the barrel. The obturator is thus suitable both for the axial and for the radial or piezoelectric percussion. By optionally mounting in the weapon the obturator and the barrel of the desired configuration, the weapon is able to use different types of cartidges, both with case and caseless. |
