Obregon pistol was a brain-child of the Mexican gun designer Alejandro
Obregon. This rare pistol has been manufactured during mid- to late 1930s by Fabrica
de Armas arms factory in Mexico city. Only several thousands of Obregon
pistol were produced; it is believed that about 800 pistols were privately
purchased by Mexican Army officers, and some more were issued to various police
forces in Mexico. In its design Obregon pistol heavily borrows on US M1911A1
pistol, although there are several original features.
Obregon pistol is
short recoil operated, locked breech pistol that uses rotary barrel locking. The
two other features that distinguish Obregon from M1911A1
are covered by Obregon patents and include single-piece safety / slide stop
lever, located on the left side of the gun, and captive return spring rod. The
basic design and shape of most other parts, including single-action trigger,
grip safety and magazine, are virtual copies of M1911A1
parts.
Disassembly of the Obregon pistol is basically the same as of M1911A1,
except that there's no separate returns spring plunger.
