Why the M1 Garand Never Got a Detachable Magazine in Combat

The M1 Garand fired eight rounds from a fixed en bloc clip — and it helped win World War II. But John Garand always believed a detachable box magazine was the right design. So why didn't the rifle ever get one? The answer involves a 1930s bureaucratic mandate, a General MacArthur veto, and a weapon — the T20E2 — that was ready to replace the Garand when Japan surrendered and made it irrelevant overnight. This is the full story of the decision that shaped the most important infantry rifle of the 20th century.
