The Semi-Automatic Rifle, Caliber 30, M1(M1 Garand)

“In my opinion, the M1 Rifle is the greatest battle implement ever devised.”

(George S. Patton)

…but it was a long time coming, and followed a rocky road of development.

(my own words... Thomas E. Ward, II, PhD)

A Brief Look Backwards• 30-40 Krag outgunned by the Mauser 7x57 in Spanish-American War

• Krag: 200 gr RN projectile @ 2,000 fps (1971 ft.lb.)

• 7x57: 173 gr RN @ 2,300 fps (2025 ft. lb.)

• M1903 Springfield Development• 30 caliber ’03

• 220 gr RN projectile @ 2,300 fps (2,585 ft.lb.)

• 30 caliber ‘06 (.30-06)

• M1906, 151 gr @ 2,700 fps (2,445 ft.lb.)

• M1 ball, 173 gr @ 2640 fps (2,678 ft.lb.)

• M2 Ball, 152 gr @ 2800 fps (2,647 ft.lb.)

• Patent infringement issues with Mauser

• The Doughboy’s Rifle: M1917 (!!!)

• Post World War I

A Few Examples of Competing Technology

Colt M1895 “Potato Digger” Machine Gun

M1_Garand_DevAndUse_v01g 8

The State of the Art & Competing Technologies

• Hiram Maxim & his machine gun (1885)• Patents on gas, recoil, and blowback operation

• Maxim & Maxim Vickers machine guns: recoil operated

• Hotchkiss Machine Gun (Mle 1897, WW I Mle 1914) – gas operated

• Browning Automatic Rifle (BAR / M1918, gas operated/piston/rod)

• Bang Rifle (I couldn’t make this up!!!)

• Johnson Rifle (recoil operated)

Grandaddy of the Garand: The Bang Rifledesigned by the Danish arms designer Søren Hansen Bang

Why Bother With Autoloading?

Increased volume of fire• Faster cycling than a bolt action rifle

• Greater soldier tolerance of perceived recoil

But there was opposition…• Concern about soldier fire discipline

• Ability of logistical system to sustain

• The “volume versus precision” debate

• Paul W. Mapes, MAJ, IN, CGSS class of 1936“Considerations against the adoption of a semi-automatic rifle to replace the present Springfield”

Primary Competitors

• Sorensen Hansen Bang: Bang Gas Trap

• Colt-Thompson Autorifle: Delayed-action Blowback (Blish Lock)

• J. D. Pederson: Toggle action

• John Garand: Gas Trap, then Gas Port

• Melvin Johnson: Recoil

How it Works:

M1_Garand_DevAndUse_v01g 17

• Gearing Up for Production• Springfield Armory - 3,526,922 M1 rifles from 1932 through 1945

• Winchester Repeating Arms - 513,880 between December 1940 and June 1945

• Combined production for Springfield and Winchester during World War II was 4,040,802 rifles

• WINNING @ Guadalcanal

Allies & Enemies

• The US started with an enormous lead• The only ally to fully field a semi-automatic basic infantry weapon

• Soviet SVT-36/38/40 (an “almost” story)

• Enemies tried and failed• German development:

• Mauser & Walther Gewehr 41 (Bang gas-trap… a failure)

• Walther Gewehr 43 (short stroke piston, much better, but too little & too late)

• Japanese attempted to copy the M-1
