Arsenal Firearms AF2011A1

Lore & Background

The original idea for a double barrel semiautomatic pistol came about ten years back to Swiss armourer Vivian Mueller, who experimented cutting and welding together parts of the Sig P210, producing a long slide, double barrel 9mm collector piece. The AF2011-A1 took the challenge further: to commemorate the legendary Colt 1911-A1 in the Centenary by making a true industrial market-ready double barrel .45 caliber pistol. Success was achieved in six months after intense 3D designing, stereolithographic modeling, and parts machining. The AF2011-A1 has its roots in the Grieco pistol, which also came with double barrels for the same purpose.

The design is practically two M1911 pistols built into a single side-by-side frame. Its barrels, triggers, magazines, and hammers all come in pairs, connected so that pulling one trigger fires both barrels. The iron sights sit between the two barrels. The majority of internal parts—including firing pins, firing pin plates, sear groups, springs, recoil rods, and mainspring housings—are interchangeable with standard M1911 replacement parts.

As of September 2015, three variants were available: the Standard Model (a double-barreled pistol based on the M1911); the Dueller (with a 6.5-inch SUS416 stainless steel barrel, serrated slide, magnum beavertailed grip, and custom trigger set); and the Dueller Prismatic (with top external compensators, 45° side ambidextrous brake ports, 6.5-inch SUS416 stainless steel barrel, serrated slide, custom trigger set, magnum beavertailed grip safety, and G10 tactical grips).

Reader's Guide

The AF2011-A1 is notable as the first industrially produced double barrel semiautomatic pistol, achieving a design that had previously only existed as a custom piece. By pairing two M1911 actions in a single frame, it effectively doubles the ballistic output of the .45 ACP cartridge without requiring a new, more powerful round. Its interchangeability with standard M1911 parts simplifies maintenance and customization. The weapon gained widespread attention through its appearance in films such as Spectre (2015), where it was fired by the villain Mr. Hinx, and in the trailer for Resident Evil: The Final Chapter, where it was dual-wielded by Milla Jovovich as Alice. It also appeared in the video games Killing Floor 2, Counter-Strike Online 2, and Phantom Forces. A viral video by Jerry Miculek, in which he fired two AF2011A1 pistols simultaneously, showed 20 rounds in 1.5 seconds and became the most viewed video on his YouTube channel as of October 2018, with over 11 million views.
