Barrel change system for one pistol *

The invention relates to a barrel change system for a Pistol, with a barrel carrier * the can be easily interchangeably connected to a grip of the pistol, this grip being a trigger device having a striker and guide parts for the releasable connection of the running beam.

To riunition different with one and the same pistol To be able to shoot caliber, such barrel changing systems have become known (e.g. for the models "Government", "Combat Commander" and "Gold Cup" from Colt Industries, Firearms Division, Hartford CT 06102, USA). Such a thing Barrel changing system usually consists of a barrel carrier, a magazine and some other parts that come with are easily detachably connected to the handle. To this Purpose, the barrel carrier has a substantially T-shaped, downwardly open groove, and the handle is with a corresponding, essentially T-shaped, guide part provided, on which the running carrier can be pushed. the Reducing the caliber has the advantage that smaller, cheaper cartridges can be used for practice shooting, which also develop less noise.

There are also known gas pressure guns, which are _{usually referred to as C0 2 guns.} In these gas _{pistols, high-tension C0 2} gases are used to drive the projectiles. The CO ₀ is either filled into a special pressure cylinder, which is "located under the barrel of the pistol, from a storage bottle or CO ^ cartridges (siphon capsules), such as those used to prepare soda water, are used. The CO ^ However, pistols differ in the design of the handle, the trigger mechanism, the weight and the weight distribution of pistols with which live ammunition is fired

the exercise effect is only given to a limited extent.

The invention is therefore based on the object a Barrel changing system for a pistol, normally used to fire live cartridge ammunition, too create, with the maintenance of the grip, which is essential for handling, for practice shooting in a cost-saving manner and environmentally friendly way air pistol bullet = ^ se can be used.

A first, particularly advantageous solution, according to the invention, is that the barrel carrier has a barrel for air pistol projectiles, that a receptacle for at least one ^{gas cartridge arranged parallel to} the barrel axis is provided in the barrel carrier below the barrel, that in the barrel carrier from the gas cartridge to the Projectile bearings of the barrel leading gas channels are provided and that in the course of a provided in the rear end of the barrel carrier, with the hammer directly or via an actuator arranged in the barrel carrier cooperating impact valve is arranged.

There is a second solution to the problem posed Invention in that the barrel carrier has a barrel for air pistol projectilesB and in its rear end an actuating member which can be driven by the hammer, and that furthermore a receptacle body which can be pushed into the magazine slot of the handle, with a receptacle for at least one gas cartridge , is provided, the gas channels leading from the gas cartridge to a connection point with the running support, in the course of which an impact valve interacting with the actuating element and a seal at the connection point having.

This new barrel change system makes it possible to use cheap and environmentally friendly air pistol projectiles for practice shooting to use, but the handling, the weight, the weight distribution and especially the trigger feel
