Frequently Asked Questions

What makes the Colt Prototype Double Action 1911 unique?

This Colt prototype is unique because it features a factory-installed double-action/single-action (DA/SA) trigger mechanism, a significant modification to the traditional single-action-only (SAO) 1911 design. It also incorporates a distinctive firing pin retracting lever for added safety.

How was the double-action mechanism integrated into the 1911 frame?

The integration involved deepening the frame to accommodate the necessary linkage for the double-action trigger. A side panel was used to protect this milled-out space and the complex internal components.

What does the 'GX' serial number prefix indicate on this Colt prototype?

The 'GX' serial number prefix is an indicator used by Colt specifically for experimental factory prototypes. This designation helps identify firearms that were part of development or testing programs rather than standard production models.

What are the safety features on the Colt Prototype Double Action 1911?

Beyond the standard manual safety and grip safety typical of the 1911 platform, this prototype includes a unique firing pin retracting lever located on the slide. This lever provides an additional layer of safety by physically retracting the firing pin.
