Also known as: Saginaw S'G' M1 Carbine, Saginaw Steering Gear M1 Carbine

Overview

The Saginaw M1 Carbine was produced by the Saginaw Steering Gear Division of General Motors, a prime contractor for the U.S. M1 Carbine in World War II. Saginaw built carbines at its plant in Saginaw, Michigan and, after taking over the failed Irwin-Pedersen contract in early 1943, at a second plant in Grand Rapids, Michigan whose output was marked 'S'G''. Across both plants Saginaw produced roughly 517,000 carbines. The Grand Rapids 'S'G'' guns are distinct collector items, while the Saginaw, Michigan plant guns are marked 'SAGINAW S'G''.

Notes

Two production sites: Saginaw, MI ('SAGINAW S'G'') and Grand Rapids, MI ('S'G''). The Grand Rapids plant was the former Irwin-Pedersen facility, taken over after that contractor failed to deliver acceptable guns.

Background

Saginaw Steering Gear stepped in to rescue carbine production at Grand Rapids after Irwin-Pedersen could not qualify a single acceptable gun, marking those receivers with the distinctive 'S'G'' code.
