  • Patent number: 10473422
    Abstract: A Flobert cartridge pistol with a barrel with a chamber, a slide, a receiver containing a hammer, a trigger, a decoupler, and an ammunition magazine in the handle of the pistol is disclosed. The double action trigger causes a Flobert round in the chamber to be fired, and the energy from the discharge of the round causes the slide to move back and the spent shell from the round to be ejected from the pistol, and engages a decoupling mechanism, which prevents the slide from cocking the hammer. The slide returns to its starting position, and the slide-return action strips a new round from the magazine and chambers the round, ready for firing.

  • Patent number: 9010227
    Abstract: The invention provides methods for producing varying sizes and types of small firearm cartridge cases using earlier produced cartridge cases as work stock. The preexisting cartridge cases are subjected to a number of machining operations to obtain the desired different sizes and/or types of cartridge cases. The invention considerably shortens the production cycle and substantially decreases the costs of production versus the conventional method of manufacturing new cartridge cases.
