Frequently Asked Questions

What was the T3E2 Garand?

The T3E2 Garand was the final trials version of John Garand's semi-automatic rifle, chambered in .276 Pedersen caliber. It was a prototype that competed to become the standard US Army service rifle in 1932 but was ultimately rejected.

Why was the T3E2 Garand not adopted by the US Army?

Despite favorable field tests, the T3E2 was not adopted primarily due to logistical concerns raised by General Douglas MacArthur. He cited the massive existing stockpiles of .30-06 ammunition and the difficulty of introducing a new caliber.

The T3E2 was lighter (9.0 lbs vs 9.8 lbs), had a 10-round capacity (vs 8), and featured a muzzle gas trap system. The standard M1 Garand used a bent operating rod to clear its larger .30-06 barrel diameter, unlike the T3E2's straight rod.

What caliber was the T3E2 Garand chambered in?

The T3E2 Garand was chambered in the .276 Pedersen caliber. This cartridge was developed by John Pedersen and offered reduced recoil and comparable ballistics to the .30-06 Springfield.
