Abstract
When a cartridge is inserted into the weapon barrel of a firing weapon by a forwardly and rearwardly reciprocatable breechblock, a front end surface of the breechblock impacts against the base of the cartridge. The cartridge to be inserted must be secured so that it cannot slide off such front end surface of the breechblock during cartridge insertion. This cartridge securement is attained in that the cartridge is held against radial displacement by an extracting or withdrawal claw and diametrically opposite thereto by means of a securing cam or lug provided at a feeler element or pin. To eject the empty cartridge case and during the insertion of the next cartridge, the feeler element or pin together with the securing cam or lug is pushed back by means of a control cam or rail.
