Italian maker's one-off shotgun marks 500 years of the company's history
Beretta has revealed a commemorative SO10 EELL sidelock over-and-under to celebrate the 500th anniversary of the company’s founding, with the engraving depicting the 1525 Battle of Pavia – a clash the manufacturer believes may have involved arquebus barrels made by its founder. The gun was announced on 27 May 2026 from Gardone Val Trompia and is the second one-off piece released this year as part of Beretta’s anniversary programme.
The battle took place a year before a receipt signed by Bartolomeo Beretta – the earliest document used to date the company’s origins to 1526 – and pitted the Kingdom of France against the Habsburg Empire. Franco Gussalli Beretta, president and CEO of Fabbrica d’Armi Pietro Beretta, explained the connection.
“The Battle of Pavia is one of the events that changed the history of the world – and of our world,” he said. “We’re in 1525, one year before the famous Bartolomeo Beretta’s receipt that allowed us to date Beretta origins around 1526, and we’re in Pavia, Lombardy, quite close from Bartolomeo’s workshop. The Val Trompia was already a reputed and designated centre for barrel manufacturing at that time – and the chances that arquebus barrels produced by Bartolomeo Beretta took part in that battle are extremely high.”
The SO10 EELL History is built in 20-bore with 30in barrels and carries more than 1,000 hours of hand engraving, with gold and copper inlays worked using hammer, chisel and burin. Spanish soldiers carrying arquebuses appear on the left sideplate; French cavalry on the right. The receiver base depicts the aftermath of the battle, incorporating a gold Beretta 500 Years logo into the scene, with the architecture of Pavia rendered as a backdrop throughout within a deep-scroll framework.
Marco Martelli, head of design at Fabbrica d’Armi Pietro Beretta, described the approach: “The representation style aligns with that of the period, in order to remain as faithful as possible to the narrative of this Renaissance historical event. The intention, of course, is not only to celebrate it, but also to showcase the level of craftsmanship and complexity that our Pietro Beretta Custom Atelier is capable of achieving.”
The receiver is machined from a solid block of high-resistance tri-alloy steel, with no casting or welding. Locking is via a rear longitudinal bolt aligned with the hinge pins, supported by two lower lugs and trapezoidal barrel shoulders. The gun is stocked in grade 5 walnut with a Tru-Oil finish and mirror-polished barrels. The case is built in solid wood covered in vegetable-tanned leather, with brass fittings and a dark Alcantara interior.

The Battle of Pavia took place in 1525 – one year before the earliest document used to date Beretta’s origins. Beretta believes the Val Trompia was already an established centre for barrel-making at that time, and that arquebus barrels produced by founder Bartolomeo Beretta may have been used in the battle.
No price has been disclosed by Beretta at the time of announcement.
