background : (wikipedia sources)
The Mateba Model 6 Unica (often known simply as the Mateba or the Mateba Autorevolver) is a recoil operated semi-automatic revolver, one of only a few of this type ever produced. It was developed by Mateba, based in Pavia, Italy.
The Mateba Model 6 uses the recoil from firing to rotate the cylinder and cock the hammer, unlike conventional revolvers, which depend on the user physically pulling the trigger and/or cocking the hammer to actuate the weapon's mechanism of operation.
The Mateba Autorevolver's barrel alignment is different from most other revolvers. The barrel is aligned with the bottom of the cylinder instead of the top. This lowers the bore axis (line of the barrel) which directs the recoil in line with the shooter's hand thereby reducing the twisting motion or muzzle flip of normal revolvers.
