The Fabrique Nationale de Herstal (FN) Model 1905 (from its patent date) or FN Model 1906 (in European countries due to its date of manufacture) were pistols manufactured from 1906 to 1959 chambered in .25 ACP (6.35mm Browning).

Described by John WalterJohn Walter as "the first truly successful 'pocket automatic' [pistol]", it was widely copied for 50 years, after its introduction, with Spanish gunmakers in the Eibar region making a large variety of unlicensed copies.

Design

The Model 1906 is basically a downsized FN Model 1903, with the return spring beneath the barrel, but the hammer was replaced with a spring-loaded striker located inside the breechblock. Until 100,000 were made, the gun had no manual safety. Afterwards, a manual catch plus a grip and magazine safeties were added to the design, allowing the pistol to be marketed as the "Triple Safety Model".

The pistol was produced with either a blued or nickel-plated finish, with the latter being prized amongst collectors.

It is virtually identical to the Colt Model 1908 Vest Pocket, which was based on the same John Browning prototype, and was the inspiration for FN's later Baby Browning design. Although Browning's handgun patents were sold to both FN and Colt, this was the only case in which both companies put the same design into production without any significant modification.

Variants

Belgium FN Model 1906 − Also known as the Vest Pocket model, it relies on a single grip safety. About 100,000 were manufactured before additional safety features were included. It was also called the Baby Browning, a nickname that eventually became an official designation for a different Browning design FN M1906 "Triple Safety Model" − An improved version with a slide catch and magazine safety added, it was produced until 1959 FN Baby Browning − Basically a modernized version introduced in 1932 with the grip safety removed

Chile F.M.G. − Also known as the F.M.E., it was a copy made by Fabrica de Material de Guerra de Santiago (the forerunner of FAMAE) complete with grip safety and slide safety at the left rear of the frame, the quality is "acceptably good".

Slides are stamped and the grips are embossed with Bergmann. Variants chambered in .32 ACP and .380 ACP were proposed but never made Continental − A cheap copy made of soft metal with poor finish, suggesting Spanish manufacture (possibly by Francisco Arizmendi of Eibar), though the safety catch is "unusually efficient" at locking the trigger and internal hammer. The slide is stamped ; the spelling of Cöln suggests it was a forgery made by Arizmendi, but Ian V. Hogg and John Weeks argue that the use of 'C' instead of 'K' was common in Germany prior to World War I and the presence of German proof marks suggests that these guns were legitimately imported into the country Dreyse 6·35mm Model 1907 − A copy made by Rheinische Metallwaaren- und Maschinenfabrik lacking the grip safety but using a different method of assembly, with the barrel inside a cylindrical piece of metal fitted to a recess into the frame and held by a snugly fit dovetail rib which also carries the sights connects the top surface of the barrel with the top of the breech block section of the slide.

The Alkar also features a peculiarly notched back strap Astra 1924 − A copy of the M1906 produced by Astra-Unceta lacking both the grip safety and slide catch, but in terms of quality, it was one of the better built Spanish copies according to Hogg and Weeks Astra 200 − Also known as the Firecat in the US, it was introduced in 1920 and remained in production until 1966.

The only markings are 6.35 on the butt grip and Continental Patent 16137 on the slide. The Continental brand name was also used by another Eibar-clone attributed to Tomas de Urizar due to the dragon motifs on the grips, though the slide markings are the same as the A&G, suggesting that both companies sold a gun made by one of them Danton − A slightly modified and renamed Bufalo with the grip safety omitted but a new slide safety added to the left rear of the frame. Around 1929 the Beristain grip safety was included. The grips are marked Danton with a GC logo on the grips Defense − A copy lacking the grip safety, the slide is marked , suggesting it was exported to French-speaking countries.
