Abstract
A pistol with a frame, a breech which is movable thereon and a rotary barrel which is located in the breech. The rotary barrel is rotated and moved axially with respect to the breech between a locked position and an open position by means of cams and grooves. In order to avoid the wear which is customary in weapons of this type, the breech is provided with a stop surface running obliquely with respect to the bore axis, and the barrel has a corresponding contact surface. During the locking by the flat contact between said surfaces, the beginning of the relative rotational movement is initiated. By virtue of this precisely guided and directed interaction, wear can be reduced by orders of magnitude relative to the prior art.

1-10. (canceled).
A pistol, comprising:
- a frame;
- a breech which is movable on the frame;
- and
- a rotary barrel which is located in the breech and configured to be in a locked position or an open position, where the rotary barrel has a bore axis and a contact surface;
- wherein the breech has a stop surface running obliquely with respect to the bore axis of the rotary barrel, and the stop surface of the breech and the contact surface of the rotary barrel are configured to come into flat contact;
- and
- wherein the rotary barrel is configured to be rotated and moved axially with respect to the breech between the locked position and the open position by the cooperation of cams and grooves.
The pistol according to claim 1, wherein the flat contact between the contact surface of the barrel and the stop surface of the breech when the barrel is in the locked position initiates a rotational movement of the barrel relative to the breech.
The pistol according to claim 1, wherein the contact surface of the barrel is disposed on at least one cam that is a locking stud configured to interact with at least one locking groove of the breech.
The pistol according to claim 1, wherein the contact surface of the barrel is provided on a dedicated cam.
The pistol according to claim 1, wherein the stop surface on the breech is provided in a region of the breech that lies opposite the frame with respect to the bore axis.
The pistol according to claim 1, wherein the barrel includes plural projections, and the breech includes a plurality of strip-shaped longitudinal guides that are parallel to the bore axis and configured so that when the barrel is in the open position the strip-shaped longitudinal guides interact with the projections of the barrel to fix the angular position of the barrel to within 8°.
The pistol according to claim 1, wherein the breech includes one or more enveloping surfaces configured to guide the barrel in an axially displaceable and rotatable, but captive manner.
