For more than thirty years the Ordnance Department endeavored to obtain a satisfactory semi-automatic or self-loading rifle to replace the bolt action Springfield. These efforts were not confined to the development within the Department. Invitations were extended periodically to gun designers in this country and abroad to submit weapons for test, and tests were made of those received which showed any promise of meeting the specifications prescribed.
During this period of thirty odd years many rifles were received and tested. Mechanisms embodying every known principle of operation were represented in the many types submitted.
After many tests of various calibers, it was decided that the caliber .276 cartridge developed sufficient power for a shoulder weapon and that the use of this smaller cartridge would facilitate the design of a reliable and durable self-loading rifle within the prescribed weight limit and would also reduce the load of the individual soldier due to the lighter weight of the cartridge. Of the several rifles in this caliber submitted for test, two were outstanding: the Pedersen; and the Garand, designed and developed by Mr. John C. Garand. Both Mr. Pedersen and Mr. Garand carried on their development work at the Springfield Armory.
A number of each of these types were manufactured and submitted to the services for test. Both rifles performed very well. However, to adopt a weapon of this caliber involved further complication of the supply problem by the introduction of another type of ammunition.
In the meantime, Mr. Garand, who has been in the employ of the Ordnance Department at the Springfield Armory for the past eighteen years as a designer of automatic weapons, completed a test model of a semi-automatic rifle designed to function with either the Caliber .30, M1, Model 1906, or the caliber .30, M1, service cartridge. This rifle appeared so promising in its preliminary tests that decision to adopt the caliber .276 was held in abeyance. The results of continued tests of the caliber .30 weapon were so excellent that the caliber .276 project was abandoned altogether and the caliber .30 weapon as developed by Mr. Garand was adopted as the standard shoulder weapon of our Army. This action was taken in January, 1936.
The new rifle, with which our troops are to be equipped, is officially known as the U.S. Rifle, Caliber .30, M1, and popularly as the Garand Semi-Automatic Rifle. It is of the gas-operated type and employs an en-bloc type of clip holding eight rounds. It varies somewhat from the conventional type of gas-operated weapon in that there is no hole drilled in the barrel is provided with a sleeve and just as the base clears the muzzle, a small amount of gas is diverted through a port at the muzzle into a cylinder where it impinges upon the piston of the operating rod, driving it to the rear. The location of the port at the muzzle rather than at some point nearer the breech permits the use of gas at a lower pressure, thereby decreasing the stresses on the operating parts of the rifle. The rifle has seventy-two component parts, which include springs, pins and screws; weighs about nine pounds; is forty-three inches overall in length; has a pistol-grip type stock; and provision is made for attaching a bayonet.
The rear sight is mounted on the receiver as close to the eye as possible and is of the aperture being seven-hundredths of an inch. The front sight is of the blade type protected by guards similar to those on the U.S. Rifle, Caliber .30, M1917.
The first production models were completed and delivered to troops in August, 1937. Since that time a small but constant monthly production, limited by the equipment available, has been maintained.
The total number of rifles for which funds have provided to June 30, 1938, is approximately 7500, and it is expected to complete the delivery of these during the current calendar year. For the fiscal year beginning July 1, 1938, funds have been provided for the manufacturer of and additional quantity of rifles, and funds have also been provided to greatly increase the equipment, such as new and more modern machines, tools, jigs, fixtures and [gages], required in the production of this weapon. These additional facilities will permit a much greater daily production rate than is now available.
In the meantime, the rifles which have been delivered to troops continue to give excellent service. Every organization so far equips has submitted enthusiastic reports of their performance under all conditions which have been encountered. Demands for this rifle to replace the Springfield are increasing tremendously as its superiority is realized from actual experience with it. This undoubtedly will result in greatly increased yearly appropriations for the production of larger quantities. Even so, it will take several years to complete the rearming of the Regular Army and the National Guard, and as priority will undoubtedly be given to equipping these organizations, it will probably be many years before any of these rifles will become available for other purposes.
I’ve never heard that it was “meant” to be loose like that...I assumed it “just was”. In full retraction the bolt is held stable only by a little stub of the bolt body and the locking lugs, whereas further forward there’s more of the bolt body, receiver guideways and charger bridge to hold it steady.
You load the M-1 with an 8 round clip. You push the clip in with your thumb, the bolt closes, and you get your thumb out of the way while the bolt closes- hopefully.
When you are not paying attention, you forget to remove your thumb in time and the bolt slams into your thumb. It happens to everyone ONCE. It does really hurt.
I’ve never had it happen while loading a clip...only when closing the bolt on an empty chamber—when you HAVE to put your thumb into the “line of fire”.
(And if it only happens ONCE, then there’s two people out there who’ve gotten away with not getting it, at MY expense!)

...from Wikipedia:
"At the time of its introduction, the .276 Pedersen was a solution to a significant problem. The US Army wanted a general issue autoloading rifle that would fire the .30-06 cartridge, but such a rifle was prohibitively large with existing designs such as the Browning Automatic Rifle and French Chauchat. A weapon of the same weight as the M1903 needed to fire a smaller cartridge. Pedersen's cartridge was viewed as a compromise as it was underpowered compared to most military rifle cartridges. This decreased recoil energy made possible a reliable, lightweight semi-automatic rifle with existing technology. Despite these early problems with semi-automatic designs, Garand's design was eventually able to handle the .30-06 cartridge; the need for a lighter caliber dissolved. The Pedersen rifle was unsuitable for the .30-06 and it, too, was dropped."
The Pedersen design involved a recoil-operated toggle-top bolt, much like a Luger pistol. It operated on a delayed-blowback principle instead of a locked breech design, which is probably why the standard .30-06 cartridge was too powerful for it. It also required dry-wax lubrication of the cartridges to enable reliable extraction of the spent cases, which the Army testing board found unacceptable. So while the rifle design was found unacceptable, the board was impressed enough with the .276 cartridge to continue working with it.
The only “serious” competitor the Garand faced was Melvin Johnson’s recoil-operated rifle of 1941, which actually did see some limited service with the Marines and OSS.
The Pedersen T1E3 was a delayed blowback operated rifle that used a toggle link lock (similar to the German P.08 Luger pistol); the Garand T3 was a conventional gas operated rifle. The .276 Pedersen T1E3 had a major drawback: it required lubrication of the cartridge to work in the action of the T1E3. Frankford Arsenal developed a proprietary dry lubricant so the cartridge would not stick in the T1E3 chamber due to its lack if primary extraction — a problem not shared by the Garand T3 rifle.
Tests held in 1929 showed the T1E3 and T3 rifles superior to other candidate rifles. Improvements were requested, including a redesign of the T3 to accept the .30-06 caliber. The Board ordered 20 each of the improved Pedersen and Garand rifles for testing.
The Army's infantry Board tested the T1E3 and T3E2 in 1931. It reversed itself and switched from favoring the T1E3 for production to the T3E2 design. One reason was the T3E2 (Garand) rifle only had 60 parts and the T1E3 (Pedersen) had 99 parts. The Board also recommended the rifle caliber be upped to .30-06. The .30-06 caliber Garand rifle was designated I1E1. Army Chief of Staff, GEN Douglas MacArthur, recommended the .30-06 caliber due to the huge amount of ammunition on hand and the likelihood of war in Asia.
The Infantry Board met once more in January of 1932. The Board decided to drop the T1E3 Pedersen from consideration, the T3E2 (.276 Garand) continued in limited procurement, and the T1E1 (.30 Garand) continued in development. Four years later the improved T1E1 rifle (T1E2) was cleared for production on 7 November 1935, and type classified as the M1 on 9 January 1936.
Between its type standardization in 1936 and its replacement by the M14 rifle in 1957, approximately 6,25 million M1 rifles were made. Producers were Springfield Armory, International Harvester (Korean War), Harrington and Richardson (Korean War), and licensed production by Beretta in Italy for NATO.
The .280 “controversy” led to all manner of problems decades later.
Along with the new .280 cartridge, the Royal Small Arms Factory design staff had created a revolutionary new rifle, the EM-1 and EM-2 “bullpup” designs. While both cartridge and rifle offered a lot of promise, Prime Minister Churchill wisely saw the need for a united caliber among NATO forces, and rejected the .280 cartridge and the EM rifle program in favor of the 7.62x51 cartridge and an inch-adapted version of the Belgian FN-FAL rifle design (the legendary L1A1 Self-Loading Rifle).
The design staff was very resentful at being rejected, as can be imagined...and about twenty years later, when the development committee for the L1A1’s replacement was formed, the head of the committee was one of the design team veterans of the rejected EM program. And instead of adopting an established design from another country, he decided that, by gum, the new British service rifle would be “an EM rifle”!
After a long series of developmental problems, engineering ineptitude, pirated design details, rigged tests, and suppressed complaints from the end users, the descendant of the EM-2 design replaced the L1A1 as the L85 Individual Weapon (better known as the SA-80). Their first major combat use was during the First Gulf War, and they were a disaster. The German arms firm of Heckler & Koch had to be called in to redesign the rifles and make them, if not ideal, at least more serviceable.
As the debacle of the M-14 rifle program contributed to the closing of Springfield Armory in 1968, likewise the grand scandal of the SA-80 blew up the reputation of RSAF-Enfield and led to its eventual dissolution soon after the SA-80 program was completed.
Don’t forget Winchester as a Garand producer!
Interestingly, the Japanese went through many of the same designs as Springfield had studied in the 1920s, during their own desperate effort to develop a semiautomatic rifle. (The Japanese Navy’s design team finally settled on a near copy of the Garand, and began production in 1945; it is believed that no more than twenty of the rifles were completed before war’s end.)
The Winchester M1 Carbine receiver was different from other producers, such as the Inland Division of GM. The operating slide guide and spring were contained in a tube that fitted in a trough in the bottom right side of the receiver. By contrast, the Inland Division receiver eliminated the trough and tube by making them part of the forging. A simple bored hole replaced the tube to hold the spring and guide. Interestingly, the original wooden M1 Carbine stock was replaced by a hand carved Vietnamese replacement.
The M1 carbine story is a testament to American ingenuity and design, when you consider that of all the companies (ten in all?) that made M1 carbines during WW2, only one (Winchester) was an established gun maker.
It’s one of the sweetest firing weapons.....
Sell me one?
Just imagine if the lighter, trimmer .276 Garand had been adopted and gradually improved over the next 60 years, like the inherent design deficiencies of the AR have been fine tuned away (almost) over the past 40 years.
Imagine a lighter M14/21 chambered for .276 with a shorter barrel and a synthetic, collapsible stock.
Sad all that was lost due to excess inventory.
Me.
I took a look at the Wikipedia link, and immediately caught the comparison to the Japanese and Italian 6.5mm cartridges.
A brief thought I had was “why wasn’t the Pedersen round revived after WW2 for something like the T48”. If the .276 Pedersen really was similar to the 6.5mm rounds I mentioned above, that might explain a lot—both the Japanese and Italians found their 6.5 cartridges lacking on the battlefield, and began transitioning over to a .30 cartridge.
