Seventy years from the first modern Beretta over-and-under (the model S1 that was launched in 1933),  a
new true sidelock shotgun is born. The SO10 over-and-under: The deserving successor of the famous Beretta
SO series hunting and competition shotguns that have earned their reputation, on the Olympic podium and
on the most exclusive hunts in the world, from Europe to America to Africa, for being the most functional,
elegant and exclusive over-and-unders in the world.
Drawing from this very long...

GRACEFUL AND  PROPORTIONED RECEIVER.
The receiver of the Beretta SO10 over-and-under, depicting exquisitely double ribbed top moldings, blends
elegantly with the classic tapered external profile of the Beretta barrels. The top moldings have been
gracefully slimmed to offer the best lateral vision during aiming. Machined from a solid block of special,
high resistant tri-alloy steel, the receiver boasts all the parts directly made from the integral piece. No part
is welded or precision cast....

INNOVATIVE LOCKING SYSTEM.
The locking system of the Beretta SO10 over-and-under features a rear longitudinal bolt operating in a
central position (between the two tubes), making the opening of the barrels  smooth and noiseless, and
minimizing stress when firing. Two additional lugs, located in the lower part of the receiver, further increase
the  strength and the efficiency of the locking system. As on the other Beretta SO models, the classic
trapezoidal locking shoulders of the barrels work in...

REMOVABLE SIDE LOCKS.
The classic Beretta sideplates can be disassembled by hand by way of two robust hidden keys, facilitating
inspection and maintenance of the firing mechanism. The visible internal parts, all newly designed, are
superbly finished...

DEMIBLOC BARRELS. 
The new Beretta SO10 over-and-under boasts demibloc barrels, manufactured for the first time using an
exclusive process of cold hammer forging. The perfect concentricity of the tubes obtained with this system
ensures lightweight barrels and exceptional strength. Years of flawless performance are guaranteed. Two
bands on the sides of the barrels help fitting between the fore-end and the tubes,  and enhance the contact
of the fore-end with the surface of the barrels. The two...

designed to enhance the concentration and distribution of shot patterns and to minimize shot deformation.
