Ian McCollum of Forgotten Weapons provides an expert-level overview of the Colt M1900, a significant precursor to the M1911. He details its unique dual-link action, the innovative but flawed sight safety mechanism, and its historical context, including military trials in the Philippines. The review highlights the evolution of John Browning's designs based on early feedback.

Quick Summary

The Colt M1900, examined by Ian McCollum of Forgotten Weapons, is a significant early automatic pistol chambered in .38 ACP. It features a unique dual-link action where the barrel moves parallel to the frame and a novel sight safety mechanism that acts as a hammer block. Despite its innovations, limitations like the finicky safety and lack of a slide stop influenced its evolution towards the M1911.

Frequently Asked Questions

What is the primary safety mechanism on the Colt M1900?

The Colt M1900 features a unique 'sight safety' where the rear sight pivots down to act as a hammer block, physically preventing the hammer from striking the firing pin. This mechanism was innovative but often criticized for being finicky in field use.

What caliber is the Colt M1900 chambered in?

The Colt M1900 is chambered in .38 ACP (Automatic Colt Pistol). This cartridge was developed by John Browning and intended for the U.S. military market, predating the more powerful .38 Super cartridge.

How does the action of the Colt M1900 differ from later pistols like the M1911?

Unlike the tilting barrel action common in later pistols like the M1911, the Colt M1900 utilizes a short recoil, dual-link system. This design causes the barrel to move parallel to the frame during the cycling process, rather than pivoting.

What were some of the limitations of the Colt M1900 noted during military trials?

During trials, particularly in the Philippines, the Colt M1900 faced criticism for its small grip, the unreliable sight safety, and the absence of a slide stop, which made reloading a two-handed operation and was a significant drawback for cavalry use.
