This guide details the disassembly of the Lewis Gas-Operated Prototype Pistol, as demonstrated by Ian McCollum of Forgotten Weapons. It covers removing the bolt assembly and understanding the gas-operated, rotating bolt mechanism. The video highlights the unique features of this experimental firearm, including its open-bolt operation and reversible firing pin, while also noting its comparison to the more practical 1911.

Quick Summary

The Lewis Gas-Operated Prototype Pistol, a miniaturized version of the Lewis LMG, features a gas-operated, rotating bolt firing from an open bolt. Disassembly involves removing the bolt assembly and observing the two-lug rotating bolt and gas piston mechanism. Despite its innovative design, it was considered less practical than the 1911.

Frequently Asked Questions

What is the operating mechanism of the Lewis Gas-Operated Prototype Pistol?

The Lewis Gas-Operated Prototype Pistol functions using a gas-operated, rotating bolt system. It fires from an open bolt, meaning the bolt stays to the rear until the trigger is pulled, at which point it moves forward to chamber and fire a round.

How is the Lewis Gas-Operated Prototype Pistol disassembled?

Disassembly involves pushing the recoil spring to remove the back plate, then sliding out the spring, guide, and bolt assembly. A sleeve over the gas piston acts as a charging handle, and the bolt itself is a two-lug rotating design.

What are some unique features of the Lewis Gas-Operated Prototype Pistol?

Key features include its open-bolt, semi-automatic operation, a reversible firing pin for redundancy, and a gas piston that cams the bolt into a locked position. It was patented in 1919 and approved in 1922.

How does the Lewis Gas-Operated Prototype Pistol compare to the 1911?

While mechanically interesting, Ian McCollum suggests the Lewis prototype was less practical than the 1911 Colt Browning. The 1911 represents a more refined and established design for military trials and general use.
