Frequently Asked Questions

What is the main mechanical difference between the Obregon and a standard M1911?

The primary difference is the Obregon's rotating barrel system, which locks the action by rotating within the slide, unlike the standard M1911's tilting barrel that drops down.

How many Obregon pistols were produced and when?

Approximately 800 Obregon pistols were manufactured between 1934 and 1938. Its intended Mexican Army contract did not materialize, contributing to its rarity.

What are some of the Obregon's design simplifications compared to the M1911?

The Obregon features a captive recoil spring and a combined safety/slide stop lever, simplifying disassembly and operation compared to the standard M1911's separate components.

Does the Obregon use standard M1911 magazines and ammunition?

Yes, the Obregon is designed to use standard M1911 magazines and fires the .45 Automatic cartridge, making it compatible with common 1911 ammunition and magazines.
