Handheld firearms with indexed magazine and compact firing mechanism

摘要

New handgun configurations are enabled by a multiple cartridge magazine that includes the firing chamber for each cartridge. A hammer with a pivot pin below and between the leading and trailing edges of a chamber strikes the primer at an acute angle. A sliding trigger mechanism with cupped ball bearings in pockets facilitate sliding motion.
