The Mondragón rifle may refer to two rifle designs developed by Mexican artillery officer General Manuel Mondragón. The initial designs were straight-pull bolt-action rifles (M1893 and M1894); those rifles served as a basis for developing Mexico's first self-loading rifle, the M1908, which was also one of the first such designs to see combat use.
Straight-pull bolt-action rifles
In 1891 Mondragón began working on a rifle design. During his stay in Belgium he filed a patent application for which he had received a grant on March 23, 1892 (No. 98,947). During the same year, on April 20, Mondragón also received a grant from the French Patent Office (No. 221,035). In the following year, on February 8, he also filed an application in the United States Patent Office (No. 461, 476) and received a grant (No. 557,079) on March 24, 1896. The rifle, referred to as M1893, was a straight-pull bolt action design, chambered for 6.5x48mm cartridge (also developed by Mondragón), with a fixed magazine fed with 8-round en-bloc clips. The rifle had three settings: "A" - SAFE, "L" - NORMAL and "R" - rapid. The "automatic" fire setting allowed the rifle to fire a cartridge each time the bolt was manually cycled to closed position, in similar fashion to Winchester M1897 pump action shotgun. The rifle could be equipped with a knife bayonet. The bayonet measured 41 cm and weighed 575 g, the blade was 28 cm long. At the time Mexico had no manufacturers capable of producing such a complex design to the required tolerances, Mondragon with the backing of Diaz entrusted the Swiss Industrial Company (Schweizerische Industrie Gesellschaft) of Neuhausen, Switzerland with the production of the rifles. SIG received the first order in 1893, for 50 rifles, and another one in 1894, this time for 200 rifles. The rifles from the second order were chambered for 5.2 × 68mm round and referred to as M1894 (to differentiate them from the ones chambered for the 6.5mm cartridge). The 5.2mm cartridge was developed by Swiss colonel Eduard Rubin.
Mondragón continued his work, and on August 8, 1904 he filed a patent application (No. 219,989) for the new rifle, this time of a self-loading design. He received the patent grant (No. 853,715) on May 14, 1907.
The design was adopted by the Mexican Army in 1908 as Fusil Porfirio Díaz Sistema Mondragón Modelo 1908. The same year, the Mexican government contracted with SIG for the production of 4,000 M1908 rifles, chambered for the 7×57mm Mauser Mexican service cartridge. Due to the Mexican Revolution, by 1910 only 400 rifles had been delivered by SIG. The rifle's inability to cope with ammunition of poor quality and the high unit cost of SFr160 per rifle, led to the cancellation of the order by the Mexican government.
The Mondragón Modelo 1908 was a gas-operated rifle with a rotating bolt and a cylinder and piston arrangement. This design is now common but was unusual at the time. The bolt was locked by lugs in helical grooves in the receiver. There was a switch, located on the charging handle, which would disengage the bolt from the gas system, changing the firearm into a straight-pull, bolt action, rifle. The rifle had a non-detachable box magazine and was filled by two, five-round stripper clips. The Mondragón Modelo 1908 rifles were fitted with a bipod. In addition to the knife bayonet introduced with the previous rifles, Mondragón designed a spade bayonet for use with the Modelo 1908, for which he filed a patent application (No. 631,283) on June 6, 1911.
Use during World War I
In 1914 the German Empire bought the remainder of the rifles produced by SIG that had not been sent to Mexico, which could have been as high as 3,600 rifles (assuming that SIG had finished their side of the deal before the cancellation). Germans tried to modify the rifles for 7.9×57mm S-Patrone (which was the service cartridge of Germany until the end of World War II), but their attempts were unsuccessful. At first the rifles were tested by the infantry, where they proved highly susceptible to mud and dirt in the trenches, a problem familiar even to less complex designs such as the Canadian Ross Mk III straight-pull bolt-action rifle. As aerial combat would provide much cleaner conditions, Imperial German Flying Corps (Luftstreitkräfte) decided to adopt the rifle, issuing two of them per aircraft crew. It was a significant improvement over bolt-action rifles (Gewehr 98) and pistols (Parabellum-Pistole), which at the time were issued to the crews. The rifle was adopted as Fl.-S.-K. 15 (Flieger-Selbstladekarabiner, Modell 1915 - Aviator's Selfloading Carbine, Model 1915) and issued with 30-round drum magazines. The drum magazine was made to Friedrich Blum's patents, which led also to the creation of 32-round drum magazine (Trommelmagazin 08) for the 1913 model of Parabellum-Pistole (LP 08). The corps used the Mondragón rifle until a sufficient number of machine guns equipped with synchronization gear became available to them. Very few of the rifles had survived the war. After the war some of the rifles were in use by Imperial German Navy. In Switzerland, the Mondragon selfloading rifle was modified for the 7.5×55mm Swiss cartridge, equipped with a 12-round magazine and a Hülsenfangkorb (a device to collect the ejected cartridges). The Mondragon equipped the World War I two-seater aircraft Häfeli DH and Blériot but was soon replaced by full-auto weapons.
Supposedly a few of the rifles were used by Mexican soldiers during an ambush on Pancho Villa. Despite the fact that some of the sources claim that the Mexican Army used the rifle since 1911, two pictures from Crónica Ilustrada Revolución Mexicana, Volume 1 on pages: 100 and 159, and an article from Guns magazine suggest that the rifle was in service as early as 1910.
