Our Assessment: Early in WW2, the US military recognized the need for a lightweight rifle that would bridge the gap between the heavy M-1 Garand and the standard issue sidearm, the M1911A1 pistol. The goal was to provide troops with a compact, easy-to-handle shoulder arm that offered more firepower than a pistol but was lighter and more maneuverable than a full-size battle rifle. In 1941, the U.S. Army’s Ordnance Department contracted with various manufacturers, including Winchester, Irwin-Pedersen, and General Motors’ Inland Division, to develop and produce the M-1 Carbine. The rifle was designed by a team led by firearms designer David “Carbine” Williams, who drew inspiration from the successful Garand and the short-recoil action of the Thompson Submachine Gun. The M-1 Carbine featured a gas-operated, semi-automatic action and fired a .30 caliber cartridge known as the .30 Carbine. The cartridge, while less powerful than the standard .30-06 round used in the Garand, offered greater capacity and reduced recoil, making it more controllable and well-suited for short to medium-range engagements. The M-1 Carbine saw widespread use in World War II in the hands of US infantry, paratroopers, Marines, and support personnel, and was loved by the troops for its ease of use, compact design, and reliability. In March 1942, Irwin-Pedersen was awarded a government contract to produce M-1 Carbines. Almost from the outset, Irwin-Pedersen faced numerous challenges during its brief production run. Issues with production quality, management disputes, and financial difficulties plagued the company, leading to a paltry output of rifles compared to other manufacturers. Convential wisdom suggests that 50,000 Irwin-Pedersen M-1 Carbines were made, though none were ever accepted by the Ordnance Department. After their contract was canceled in April 1943, all of their completed M-1 Carbines, spare parts, tooling, and facilities were taken over by the Saginaw Gear Division of General Motors. This Irwin-Pedersen M-1 Carbine features a Rock-Ola barrel; the mix of maker’s parts is correct, as Rock-Ola was one of the barrel suppliers to Irwin-Pedersen. Today, any Irwin-Pedersen M-1 Carbines remain sought after by collectors for their historical significance and relative rarity. Please see our photos and best of luck with your bidding!!! -R.L.
