In April, 1897. John M. Browning of Ogden. Utah, met Hart O. Berg, commercial director of the F. N. (Fabrique Nationale) armsmaking firm. Herstal. Belgium. This important meeting began a relationship which resulted in F. N. producing a variety of Browning-designed small arms, among them a blowback-operated semi-automatic pistol chambered for the .32 ACP cartridge.

Commonly called the Model 1900. this pistol was first produced in Jan.,

1899. It was the first Browning-designed pistol to be put into production and the first arm chambered for the .32 ACP cartridge, which was also a Browning development.

There are various names for this pistol. While it is commonly called Model

1900, it is listed as Model 1899 in the official history of the F. N. firm. A German Burgsmueller arms catalog of 1912 called it the original Browning repeating pistol, large model and did not give a model designation. The Model 1900 designation used in this article is by far the most popular and commonly used for this arm.

The Model 1900 became popular immediately. and was sold in large quantity. In 1900. this pistol was adopted by the Belgian government for arming its officers, and it was also used extensively

1909, 500.000 of this model had been produced, and it was discontinued about 1912 when the Browning Model 1910 pistol was introduced.

Weighing only 22 ozs. unloaded and measuring 6Vs" in overall length, the Model 1900 is an excellent pocket arm. Its detachable magazine which holds seven rounds is released by pressing forward the magazine catch at the lower rear of the frame. Handling qualities of the pistol are generally favorable except that the grip is almost at a right angle with the line of bore, which is not good for natural pointing.

Screwed rigidly into the frame, the barrel is housed in the slide under the recoil spring. The breechblock is fastened to the slide with two screws, and holds the cocking lever, firing pin, and extractor. A V notch in the top of the breechblock serves as the rear sight. The front sight is on the slide.

A very clever and desirable feature of this pistol is that the recoil spring is also used to drive the firing pin. Another clever feature is the method of attaching the checkered hard rubber grips to the frame by means of concealed retainers. After the grip screws are loosened, the retainers can be turned out of engagement with a screwdriver or similar tool inserted in the magazine opening of the frame. The grips are then easily removable to facilitate cleaning.

The safety on the upper left side of the frame is on safe when pivoted upward. With the safety in this position, the sear and the slide and breechblock assembly are blocked, and the marking "SUR" (French for safe) is exposed on the frame. Turning the safety down to fire position exposes the marking "FEU" (fire). The safety can also be used to latch the slide and breechblock assembly to the rear—a very desirable feature.

When the pistol is uncocked, the upper tip of the cocking lever projects above the breechblock in such a manner that it blocks the line of sight. It is thus possible to determine by sight or touch whether the pistol is cocked.

The Model 1900 had such an excellent reputation for sound design and reliability that several of its features were used in other makes of European-produced pistols. Also, many crude copies of the Model 1900 were turned out. These are generally believed to be of Oriental origin, although it is not actually known who produced them. Original specimens produced by F. N. are of high-quality workmanship and finish throughout. Most have blued finish and hard rubber grips, although it was possible to obtain nickel-plated specimens with mother-of-pearl grips at extra cost. ■

IPush the magazine catch (25) forward and remove the magazine (9). Release the safety (19). Draw the slide (4) fully to the rear and check visually that the chamber is empty. Release the slide and pull the trigger. Unscrew and remove the breechblock screws (5) (6), and move the slide forward off the frame (26). Lift the forward end of the recoil spring (1) until it snaps free of the frame. Withdraw the breechblock (11) to the rear. This is sufficient disassembly for normal cleaning. Disassemble further only as required.

2 Insert a narrow screwdriver blade beneath the hook of the extractor (14). Push the extractor outward until its lug clears the side of the breechblock. Then, pry the extractor forward, bringing its wings into alignment with the disassembly hole. Drift out the cocking lever pin (27), and remove the recoil spring mechanism. Drift out the breechblock plug pin (30) to release the breechblock plug (32) and firing pin (31).

5 In reassembly, replace the trigger and trigger pin, and install the sear spring through the top of the frame. Align the spring vertically, and lever it horizontally against the left side of the frame. Insert the tail of the sear between the sear spring and frame backstrap, and replace the sear pin. Install the safety spring from below, sliding it upward

3 To release the grips (10 (16), first loosen the grip screws (15) and turn the grip retainers (17) from horizontal to vertical with a screwdriver inserted through the bottom of the magazine well. Drift out the magazine catch pin (24), and remove the magazine catch (25) and trigger bar spring (29). Pull the forward end of the trigger bar (22) downward into the magazine well and remove. Move the safety midway between safe and fire positions and push out with a punch.

4 Drift out the sear pin (23) and lift out the sear (8). Push the safety spring (28) downward and remove through the underside of the frame. Center the sear spring (7) in the frame with a screwdriver blade, and push upward to remove. Drift out the trigger pin (20), roll the bottom of the trigger forward, and remove through the side of the trigger guard.

6 Safety must be disengaged to install the breechblock. Depress the trigger and start the breechblock assembly into the frame until resistance is felt, then release the trigger and push the breechblock fully home. Again depress the trigger and pull forward on the recoil spring to release the firing pin from the sear. Grasp the rear of the recoil spring tightly and pull forward over the recoil spring guide (3), until the assembly can be swung down within the frame fork.

against the right side of the frame and behind the sear. Flex the safety spring with padded long nose pliers when installing the safety. Inset shows proper location of springs in the frame. All seat upon the fixed frame pin (A), which is never removed.

Deer hunting is an interesting thing that reminds you of those golden old ages of 19th centuries, where a handsome hunk well equipped with all hunting material rides on horse searching for his target animal either for the purpose of displaying his masculine powers or for enticing and wooing his lady love.
