Identifying and differentiation the FN Browning Pistols:
FN Browning Model 1899 and 1900,
FN Browning 1903,
FN Browning 1905 (1906) Vest Pocket and Baby Browning pistols
FN Browning Model 1910 and Model 1922

Following is a guide for identifying FN Browning pistol models:

FN Browning Model 1899 vs. FN Browning Model 1900: The Model 1899 was first produced in January 1899 and closely resembles John Browning's prototype. It can be differentiated from the FN Model 1900 by the following features: There are no safety markings and no lanyard ring, the frame has small side-plates. The grips are secured with studs and nuts. The FN Browning 1900 was introduced in 1900 after Belgian military trials requested changes to the Model 1899. The Model 1900 has larger grips which are secured with screws, has French language safety markings (Feu & Sur), a lanyard ring and larger frame side-plates.

FN Browning Model 1903: The Model 1903 in 9mm Browning Long was manufactured for the military market. It was not a copy of the Colt 1903 as is often reported. FN requested a (military) handgun design from John Browning in 1901. The same prototypes were presented to Colt and FN, Colt opted to manufacture a pocket pistol while FN tried to fill a void in their line by offering the design as a military pistol.

FN Browning Model 1905 / 1906 vs. FN Baby Browning: The Model 1905 is often referred to as the Model 1906, generally in the U.S. it is known for its first patent year '1905' while in Europe, 1906 refers to FN's first manufacturing year. This model is also commonly known as the Vest Pocket model. The Baby Browning was introduced by FN in 1931, the pistol is smaller than the Vest Pocket model. The Baby Browning is a total different design from the earlier Vest Pocket pistol, parts are not interchangeable.

Beware of Walther style PP pistols that are on the U.S. market with FN - Fabrique Nationale - slide legends…

These are not FN made pistols and do not feature the typical FN quality. The PP pistols were made in one of the former Soviet countries and are available with any marking or manufacturers marking at extra cost. Somebody ordered a batch of these pistols with FN’s older legal name marked on the slide, this was done solely to mislead buyers / collectors into believing that they were getting a genuine FN made gun. FN never produced the PP and these were not made for the Belgian police as often claimed in U.S. advertising. Belgian law-enforcement agencies did not use the PP or PPK.

Popular misconceptions on FN
and FN Browning Firearms

The following misconceptions circulate in the international collector community. Here are some answers and comments that may clarify how the facts were misunderstood.

General History

FN was a German company?!

FN has always been a Belgian company, from its inception up to the World Wars. It should be noted that the company did endure a German majority take-over from 1896 to 1914. In such, the majority of shares were in hands of a German company. Majority ownership however does not mean that a company changes national identity. During both World Wars the company was sequestered and under German control.

FN was established by Loewe in Germany?!

The Belgian government (not FN) purchased the production rights for the 1889 Belgian Mauser and ceded those to FN. Loewe had no influence or control in the establishment of FN. FN engineers did purchase equipment and technical assistance from Loewe after the company was in existence. Loewe was selected after FN engineers had explored buying their machinery in the U.S. but ran into problems when U.S. manufacturers did not want to modify and make the machinery on metric specifications.

FN was crucial to the German war effort and produced many guns for the German military?!

FN was not one of the most useful bodies to the Germans in WWII. Instead it was more a source of aggravation for the Germans, as they could not get production up to desired significant numbers prior to 1943.

FN Browning Pistols

The Browning 1900 was the first Browning produced pistol?!

Because no research was done for decades, the first Browning pistol is often credited to the FN Browning 1900. We know now that the 1900 was a modified 1899 model. The 1899 was the first of the Browning pistols to go into production at FN in January 1899. The 1900 followed in mid 1900 after the Belgian military requested changes to the original Browning design. There is a clear distinction between the 1899 and 1900 models, their production run and production periods.

The Belgian army adopted the FN 1903 and 1922 in the pre-WWII era?!
