The M1 Garand (officially designated as United States Rifle, Caliber .30, M1, later simply called Rifle, Caliber .30, M1, also abbreviated as US Rifle, Cal. .30, M1) is a semi-automatic rifle chambered for the .30-06 Springfield rifle cartridge.
The M1 is an air-cooled, gas-operated, clip-fed, semi-automatic, shoulder-fired weapon. This means that the air cools the barrel; that the power to cock the rifle and chamber the succeeding round comes from the expanding gas of the round fired previously; that it is loaded by inserting an en-bloc (i.e., it goes into the rifle's action and functions as part of the rifle) metal clip (containing eight rounds) into the receiver; and that the rifle fires one round each time the trigger is pulled. After the eight rounds have been shot, the empty clip automatically ejects with an audible "ping" noise.
Development
French Canadian-born Garand went to work at the United States Army's Springfield Armory and began working on a .30 caliber primer-operated breech. In the summer of 1924, twenty-four rifles, identified as "M1922", were built at Springfield. At Fort Benning during the summer of 1925, they were tested against models by Berthier, Hatcher-Bang, Thompson, and Pedersen, the latter two being delayed blowback types. This led to a further trial of an improved "M1924" Garand against the Thompson, ultimately producing an inconclusive report. As a result, the Ordnance Board ordered a .30-'06 Garand variant. In March 1927, the Cavalry Board reported trials among the Thompson, Garand, and '03 Springfield had not led to a clear winner. This led to a gas-operated .276 model (patented by Garand on 12 April 1930).
During the spring of 1928, both Infantry and Cavalry Boards ran trials with the .276 Pedersen T1 rifle, calling it "highly promising" (despite its use of waxed ammunition, shared by the Thompson). On 13 August 1928, a Semiautomatic Rifle Board carried out joint Army, Navy, and Marine Corps trials between the .30 Thompson, both cavalry and infantry versions of the T1 Pedersen, "M1924" Garand, and .256 Bang, and on 21 September, the Board reported no clear winner. The .30 Garand, however, was dropped in favor of the .276.
Further tests by the SRB in July 1929, which included rifle designs by Browning, Colt-Browning, Garand, Holek, Pedersen, Rheinmetall, Thompson, and an incomplete one by White, led to a recommendation that work on the (dropped) .30 gas-operated Garand be resumed, and a T1E1 was ordered 14 November 1929.
Twenty gas-operated .276 T3E2s Garands were made and competed with T1 Pedersen rifles in Spring 1931. The .276 Garand was the clear winner of these trials. The .30 caliber Garand was also tested, in the form of a single T1E1, but was withdrawn with a cracked bolt on 9 October 1931. A 4 January 1932 meeting recommended adoption of the .276 caliber and production of approximately 125 T3E2s. Meanwhile, Garand redesigned his bolt and his improved T1E2 rifle was retested. The day after the successful conclusion of this test, Army Chief of Staff General Douglas MacArthur personally disapproved any caliber change, in part because there were extensive existing stocks of .30 M1 ball ammunition. On 25 February 1932, Adjutant General John B. Shuman, speaking for the Secretary of War, ordered work on the rifles and ammunition in .276 caliber cease immediately and completely and all resources be directed toward identification and correction of deficiencies in the Garand .30 caliber.
On 3 August 1933, the T1E2 became the Semi-Automatic Rifle, Caliber 30, M1. In May 1934, 75 M1s went to field trials; 50 were to infantry, 25 to cavalry units. Numerous problems were reported, forcing the rifle to be modified, yet again, before it could be recommended for service and cleared for procurement .
