Abstract

The present invention relates to a changeover system for a hand gun comprising at least two different barrels, able to be applied exchangeably on a first grip piece of a weapon, for bullets of different caliber, and/or at least two different magazines for cartridges of different caliber able to be applied exchangeably on a first grip piece of a weapon. According to the invention, the changeover system comprises at least a second grip piece of the same weapon type, provided for a smaller caliber, on which at least one security arrangement against interchange is provided, which prevents the application of a barrel and/or of a magazine of a larger caliber on the grip piece provided for a smaller caliber. If required, the user of a second large-caliber weapon can then mount components of the small-caliber weapon onto the grip piece of the large-caliber weapon, in order to fire small-caliber ammunition therewith, for example for training purposes. The risk that the barrel or the magazine of the large-caliber weapon are mounted by mistake onto the grip piece of the small-caliber weapon does not, however, exist because this is prevented by the security arrangement(s) against interchange on the grip piece of the small-caliber weapon.
