Frequently Asked Questions

What was the purpose of the Pedersen Device?

The Pedersen Device was a secret weapon intended for World War I. Its primary purpose was to convert the standard bolt-action U.S. Rifle Model 1903 into a semi-automatic firearm, increasing its rate of fire on the battlefield.

How is the Pedersen Device installed on an M1903 rifle?

Installation involves setting the rifle's cutoff tab to the mid-position, removing the standard bolt, and then sliding the Pedersen Device into its place. A 40-round magazine is then inserted with a specific 'in, back, forward' motion.

What caliber cartridge does the Pedersen Device fire?

The Pedersen Device switches the rifle's operation from the standard .30-06 manual firing to semi-automatic firing of a .30 Pedersen cartridge. This is a .32 caliber pistol-style cartridge, resulting in minimal recoil.

What were the main reliability issues with the Pedersen Device?

The Pedersen Device suffered from frequent jams, largely due to limited space for the extractor. While it could manage consecutive shots, its overall reliability was a significant concern for military adoption.
