The Semi-Automatic Revolvers
Semi-Auto Revolvers Page

Two of the revolvers that used the recoil to turn the cylinder.

Webley-Fosbery
The upper half of the pistol was mounted on a reciprocating slide. As a cartridge was fired, the recoil pushed the slide back, cocking th hammer and moving the cylinder against a pin mounted to the frame, which mated with zig-zag grooves cut into the cylinder. This caused the cylinder to rotate and bring the next cartridge in line with the hammer.

Mateba Model 6 Unica
The first triggerpull is a normal double action pull, it cocks the hammer, and then releases it, firing the gun. Upon firing the upper part of the frame recoils. This movement then cocks the hammer, and automatically rotates the cylinder. When the upper frame has completely recoiled, it is pushed forward again by a spring. When it has returned to its forward position the gun is ready to fire another shot, only this time a light pull in Single-Action mode, as the hammer is already cocked and the cylinder rotated.
