This review details the rare Gas Trap M1 Garand, an early design by John Garand that avoided a barrel gas port. It captured gas at the muzzle to cycle the action, a system later abandoned due to safety concerns and production complexities. Only about 51,000 were made before the switch to the more reliable gas port system in 1939.

Quick Summary

The original Gas Trap M1 Garand design by John Garand used a muzzle device to capture gas, avoiding barrel port drilling. Adopted in 1936, only about 51,000 were made before safety issues and production complexities led to its replacement by the gas port system by 1939.

Frequently Asked Questions

What made the early M1 Garand design unique?

The early M1 Garand, known as the Gas Trap model, featured a unique muzzle device designed to capture gas behind the bullet to cycle the action, avoiding a gas port drilled directly into the barrel.

Why was the Gas Trap M1 Garand replaced?

The Gas Trap system was replaced primarily due to safety concerns. A loose gas plug could misalign, leading to potential catastrophic failure where the bullet could strike the plug and blow off the gas cylinder.

How rare are original Gas Trap M1 Garands today?

Original Gas Trap M1 Garands are extremely rare. Most were destroyed or modified into the later gas port configuration, especially after a 1947 order mandated the destruction of remaining gas trap rifles.

How does the Gas Trap M1 Garand's disassembly differ from later models?

Disassembling the Gas Trap M1 Garand involves removing the front sight screw, which allows the entire gas cylinder assembly to be unthreaded from the barrel, unlike later models with different attachment methods.
