This guide provides an overview of the Gabbet-Fairfax Mars Pistol's unique mechanical features, as explained by Ian McCollum on Forgotten Weapons. It covers the four-lug rotating bolt, the unconventional magazine feeding system that extracts cartridges rearward, and the single-action-only operation. The video highlights the pistol's historical significance as a powerful self-loading pistol and its complex, albeit functional, operating cycle.

Quick Summary

The Mars Automatic Pistol, a historically powerful self-loader, features a unique four-lug rotating bolt and an unconventional feeding system. Cartridges are pulled rearward from the magazine by 'cartridge grabbers,' then fed into the chamber. It operates single-action-only and weighs 3 lbs 5 oz, with a disconnector that delays bolt closure for improved feeding reliability.

Frequently Asked Questions

What is the primary unique feature of the Mars Automatic Pistol's feeding mechanism?

The Mars Automatic Pistol features a unique feeding mechanism where cartridges are pulled rearward out of the magazine by 'cartridge grabbers,' then lifted and pushed forward into the chamber by the bolt.

What type of action does the Mars Automatic Pistol utilize?

The Mars Automatic Pistol is a single-action-only (SAO) firearm. This means the trigger performs only one function: releasing the hammer or striker, which must be cocked prior to each shot.

How does the Mars Automatic Pistol's weight and handling compare to other firearms?

The Mars Automatic Pistol weighs 3 pounds 5 ounces and is described as very hefty. The shooting experience is compared to firing a cinderblock, despite its ergonomics being rated as 'not terrible'.

What is the function of the disconnector in the Mars Automatic Pistol?

The disconnector in the Mars Automatic Pistol holds the bolt locked back as long as the trigger is depressed. This delay allows cartridge oscillation to dampen, potentially improving feeding reliability when the trigger is released.
