The Obregón is a Mexican designed semi-automatic pistol designed in the mid-1930s by the mechanical engineer Alejandro Obregón.[1]
History
[edit]Fewer than 1,000 of these pistols were produced at the national armory, Fabrica de Armas Mexico, in Mexico City between 1934 and 1938.[2][3] It was not a sales success, nor was it commissioned by the Mexican government.[3] Some were acquired by private purchases by Mexican soldiers with the pistol issued to Mexican police officers.[1]
The pistol's patent was registered in 1934 (Mexico) and in 1938 (USA).[3]
Design
[edit]The Obregón uses the same .45 caliber ammunition as the Colt 1911 and it resembles the 1911 in overall appearance, frame size and weight. However it features a rotating barrel locking system. This system employs a diagonal cam on the rear of the barrel sliding against a diagonal receiver-mounted groove that rotates the barrel. This is like the Austro-Hungarian Steyr M1912 pistol, unlike the "swinging link and pin" of the Colt M1911 series.[3]
The pistol disassembles similarly to the 1911.[1]
One of the Obregón's design simplifications is that the safety switch and the slide lock are a single unit.[4] It also has a magazine safety.[4]
