Mateba Model 6 Unica, aka the Mateba Autorevolver
Manufactured by Macchine Termo-Balistiche in Pavia, Italy, following the design of Emilio Ghisoni. This example is chambered in .357 Magnum/.38 Special, but this revolver was also produced in .44 Magnum/.44 Special and .454 Casull/.45 Long Colt - switching from a cartridge to another with a given caliber required to change the frame’s spring for the weapon to cycle properly.
As per usual with Mateba revolvers, it features a six o’clock barrel, aligned with the bottom chamber of the swing-out hexagonal six-round cylinder in a way that - supposedly - suppresses barrel flip by aligning the barrel with the user’s hand, a profile even more pronounced in the Mateba MTR series.
The most distinctive feature of the Mateba Unica however is that it is one of the very few commercial automatic revolver design in existence, like the Webley-Fosbery series, and the only one to have been produced in living memory (except for a bunch of very old ladies that were born around 1900, they might remember that since the production of the Webley-Fosbery ran up to 1915).
Upon firing the revolver, the whole frame, cylinder and barrel would slide back on the handle for about 12mm - sorry for my Imperial buddies, I don’t care - and cock the hammer for the next shot.
A very cool-looking, cyber-punkish gun that’s both sexy and unique.
Also exists as the Griffone Carbine for extra sexiness !
