The Frommer Stop is a Hungarian long-recoil pistol. It was designed by Rudolf Frommer, and its original design was adopted as the Pisztoly 12M in 1912. The handgun was manufactured in various forms from 1912-1945 and used in the Hungarian Armed Forces. 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 7 rounds.


The predecessor to the Stop pistol, the M1910, was chambered in a proprietary 7.65mm (.32 ACP) 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.

And here are some older (and much uglier) models of Frommer's pistols:

Frommer’s first pistol design was the Model 1901, which reached market in 1903 and was not successful (only about 200 were made). It was submitted to several military trials, but did not win any of them. It had a 10-round blind magazine fed from the top by stripper clips, and was chambered for the 7.65mm, 8mm, and 9mm cartridges.

Next iteration was the Model 1906. The first few 1906 pistols retained the early 10-round blind magazine, but the design was soon revised to use a more modern but smaller capacity 8-round removable magazine (which would serve as the model for the Luger P08 magazine). The Model 1906 was chambered for a proprietary cartridge, the 7.65 Frommer. This model is also very rare, with only about 800 made. They were tested by the Austrian military, but lost out to the Roth-Steyr (which would be made in the same factory where Frommer worked).

The third, and most successful variant to date was the Model 1910. This Frommer used the same long-recoil action and proprietary cartridge as its predecessors, but had a number of modernizations. The spur hammer was replaced with a rounded one, and the manual safety was replaced with a grip safety. It was used by the Hungarian police, and many more were made than the previous models (although still fewer than 10,000 in all).
