Fusil M-1908 "Mondragón"
Diagram from original patent, issued to Gen. Manuel Mondragon
for his self-loading rifle design.
The development of firearms in the nineteenth century led
rifle designers and inventors to conclude that once they had a reliable
composite cartridge and a magazine system that worked, the next logical step
was to harness the recoil of the weapon, or the gases produced by the fired
cartridge, to enable the weapon to reload itself. This step was needed for at
least two reasons: automatic reloading saved the user from the continuous
physical effort of manual reloading, and it enabled infantry to fire more rapidly,
which was of great importance at shorter ranges.
Resistance to the unwarranted expenditure of ammunition was
still felt, particularly in the United States and Great Britain, where musket
experts and instructors maintained that well-aimed single shots were needed at
longer ranges and at battle ranges. U.S. and European rifles were fitted with
sights that went up to (on average) over 1,000 yards, and some went out to as
far as 2,400 yards. The individual rifleman, it was argued, could be effective
up to about 600 yards or even 800 yards, and the rifle group (section, platoon,
even company) could, under control and with specific fire orders, lay massed
fire out to ranges now considered totally wasteful of ammunition.
The arrival of heavy and medium machine guns took over the
supporting and interdictory fire roles previously assumed by the riflemen, for
machine guns could range out to even 3,000 yards and deliver concentrated fire
with effect. Rifles were now to be used for the ranges at which sight of the
enemy was possible. The situation still suffered, however, from the desire of
all musketry instructors to save ammunition. The opposite of this argument was,
of course, that saving ammunition for its own sake meant that trained riflemen
were loathe to fire at fleeting targets, thus allowing the enemy the
opportunity to close, at which point the assault final occurred.
There is little doubt that in the United States ammunition
expenditure was a prime factor in deciding what type of rifle to issue to troops.
The powers at Springfield Armory were still strong, and the issue of the Mauser
copy, the Model 1903, happened at the same time as Mexican gun designer Manuel
Mondragon was preparing his self-loading rifle for use by the Mexican Army.
Claims for the first SLR go back a long way before this, and
in the British official Textbook of Small Arms 1929 there is a note that the
principle of the automatic weapon “appears to have been a British invention,” a
claim that is based on an entry in the records of the British Royal Society.2
It was informed that “there had come to Prince Rupert a rare mechanician who
pretended . . . to make a pistol shooting as fast as could be presented and yet
to be stopped at pleasure; and wherein the motion of the fire and bullet within
was made to charge the piece with powder and bullet, to prime it and bend the
cock.” Either the report was true or the most amazing confidence trick was
being perpetrated.
There are other reports of early self-loading devices, and
it is clear that the principle, if not the method, of making weapons that
reloaded themselves was known. However, until the invention of the composite
cartridge and the magazine, little or no progress could be made to realize this
dream. Hiram Maxim made a good try at it with his mechanical recoil system, and
others had patented designs twenty years before him. Maxim used the recoil of
the whole weapon to operate the Winchester lever action by means of a butt
plate against which the rifle recoiled, attached by a lever system to the
rifle’s actuating lever. The problem with this weapon was that the user had to
be very careful of where his fingers were at the moment of firing.
Although almost totally ignored in the United States, the
device had considerable success in Europe, and the Turkish Army issued such
modified Winchester rifles. Then, in 1884 Maxim patented his locked-breech
recoil system. This was an application for machine guns, but the concept was
quickly taken on board by other weapons designers, and in 1885 the Mannlicher
short-recoil SLR appeared. This was nothing more than an experimental piece,
but it laid down the principles upon which such weapons were to be developed.
The period 1885–1900 saw a great deal of work and a number
of rifles that were truly self-loading, even though the majority were too unreliable
to be issued to troops or even tested by the military. The Mondragon, however,
had a different history. Mannlicher had no success in selling his
semiautomatics to the military, but the Mondragon came from Mexico, where it
had already been tested. Porfirio Díaz (1830–1915), the Mexican dictator
(president of Mexico from 1876 to 1880 and again from 1884 to 1911), decided
that the Mexican Army would be entirely armed with automatic rifles. The rifle
chosen was that designed by Mondragon (1858–1922). Progress in developing the
weapon was slow, and eventually the rifle was manufactured in Switzerland by
Schweizerische Industrie-Gesellschaft (SIG). Only 400 of the rifles were
delivered, too late to save Díaz, who was ousted in the revolution of 1911. The
new Mexican government reneged on the contract, and SIG stored the 1,000 rifles
it had produced but not delivered.
At the start of World War I, SIG decided to cut its losses
by offering the Mondragons to any taker. A few went to the United States, but
the majority were sold to the Germans for use in aircraft. The weapons only
went into action in 1917, with most going to the German Air Force, the rest to
the navy. By this time the weapon was known as the FSK-15 (Flieger
Selbstladerkarabiner: Airmen’s Self- Loading Carbine, Model 1915). The weapon
was not a great success even though the Germans issued it with a 30-round drum
magazine. It suffered from stoppages and malfunctions, and most were withdrawn from
service before the war ended, due not only to the rifle’s unreliability but
also to the fact that fixed machine guns were totally effective following the
invention of interrupter gears, which stopped the machine guns from firing when
the propeller blades were liable to be hit by the machine gun bullets.
The Germans did not rely solely on the Mondragon, however;
Mauser designed an SLR (Flieger-Ballon-und Zeppelin Truppe Model 16), of which
1,000 were made. They had to be kept scrupulously clean, but demand far
exceeded supply. Further manufacture was a problem not addressed by Mauser, and
the weapons that survive are extremely rare. The idea had caught on, however,
and the Germans never stopped experimenting with SLRs. The first of Mauser’s
postwar SLRs was the G35, designed as a result of the success of the Czech
ZH-29 SLR (designed by Vladimir Holek; hundreds were sold, including at least
500 to Manchuria). The G35 was a short-barrel recoil weapon and was out of
favor compared with the gas-operated systems appearing elsewhere, which were
more conventional in barrel length. Walther (the firm of Carl Walther in
Zella-Mehlis had been making firearms since 1886, and its reputation grew
enormously in the twentieth century) designed the A115, which was a gas-operated
weapon relying for manufacture on sheetmetal stampings, and from that came the
later developments in German weapons manufacture (particularly the MG42, the
MP40, and the MP44/StG range of weapons). Once more technical and operational
problems arose while the weapon was being tested, and German SLR development
faltered in 1938, only to be revived a few years later.
