The Arsenal Firearms AF2011-A1 is a double-barreled, semi-automatic pistol of Italian origin. The weapon is a derivative of the M1911 pistol and the majority of internal parts including the firing pins, firing pin plates, sear groups, springs, recoil rods, and mainspring housings are interchangeable with standard M1911 replacement parts. The purpose of the AF2011A1 pistol is to increase the ballistic capability of .45 ACP without the need to develop a more powerful round. The AF2011A1 has its roots in the Grieco pistol that also came with double barrels for the same purpose.


The AF2011-A1 Double Barrel Pistol comes actually as the very first industrial double barrel semiautomatic pistol of all time. The original idea came about ten years back to Swiss armourer Vivian Mueller, who at the time experienced cutting and welding together multiple parts of the famous Sig P210: the result was a long slide, double barrel 9mm, highly decorated collector piece, which indeed shot very well. Our idea 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. We achieved success in the brief span of 6 months, after intense and round-the-clock 3D designing, stereolithographic modeling and parts machining.

— Arsenal Firearms AF2011 Description


The AF2011-A1 is double barreled pistol based on the design of the M1911. It is practically two M1911 pistols built into a single side-by-side frame. Its barrels, triggers, magazines, and hammers all come in pairs, and are connected together so that pulling on one trigger would fire both barrels. The iron sights sit between the two barrels.[7]


The available cartridges for the AF2011-A1 are:

  • .45 ACP
