The Frommer Stop is a Hungarian long-recoil, rotating bolt pistol manufactured by Fémáru, Fegyver és Gépgyár (FÉG) (Metalware, Weapons and Machine Factory) in Budapest. It was designed by Rudolf Frommer, and its original design was adopted as the Pisztoly 12M in 1912, created for the Royal Hungarian Army. The handgun was manufactured in various forms from 1912 to 1945 and used in the Hungarian Armed Forces as well as, during the First World War, by the Ottoman Army in limited quantities. The Stop is 165 millimeters (6.5 in) long with a 95 millimeters (3.7 in) 4-groove rifled barrel. Unloaded weight is 610 g (22 oz), and the detachable box magazine holds seven rounds.[1]

The Stop incorporated design features of earlier Frommer pistols including the Model 1901 (M1901) and M1904 derived from the Roth–Theodorovic pistol.[2] The predecessor to the M1911, the Stop pistol was chambered in a proprietary 7.65mm (.32-caliber) cartridge having a crimp in the casing at the base of the bullet. This round achieved a velocity of 920 feet per second (280 m/s) from the gun. Frommer redesigned the pistol with a more conventional layout. Patented in 1912, this variant was produced from 1919 to 1939, under the name Pisztoly 19M. It was adopted as the official sidearm of the Hungarian Armed Forces. The last variant of the Stop, the Pisztoly 39M, was produced in 9mm Kurz (.380 ACP); however it was never adopted as a service pistol.[1]

Machine Pistol

Beginning in 1916, the Austro-Hungarians made several attempts to replicate the Italian Villar Perosa submachine gun. In 1917, FÉG converted two .380 Frommer Stop pistols into automatic machine-pistols with 25 round magazines and fitted them side-by-side to a central mount with a tripod. The machine-pistols were mounted upside-down, and the magazine catches were enlarged for easier unloading. The triggers were removed, and the guns were operated by a set of rods connecting to the spade grips of the mount, which directly engaged the sears. The barrels were lengthened and the cocking mechanisms were redesigned as protruding arms, which were engaged by a set of hinged retracting levers. [3][4]

This Frommer submachine gun was designed to be used as a light support machine gun like the Italian weapon. Although it was tested by the Austro-Hungarian Army, it was not successful and was only made in small numbers. The Frommer machine-pistol was succeeded later in 1917 by the more successful Sturmpistole, a direct copy of the Villar Perosa.[5]
