rifle caliber question

[Zack]

Someone told me the 30-06 in the m1 garand is the same as the m1a1 .30cal? Is this true? Also he said the reason the tompson has a M1A1 logo stampped on it is that its part of the m1a1 family??????

 

[paintballdude902]

m1 garand is .30-06

m1a1? as in the m1 carbine? if its the carbine it is chambered in ".30 carbine"

the thompson is chambered in .45acp same as the 1911a1 pistol

 

[Water-Man]

M1 Garand - .30-06
M1A1 - .30 Carbine
M1A - .308

There was a model M1 Thompson SMG. I don't know if it was an M1A or not, but remember handling one back in my ROTC days. Perhaps one of our military buffs will jump in.

The Thompson as used by the army at the opening of the second world war was the 1928 model. The '28 was expensive and time consuming to produce so it was simplified and the first version was the M1. The M1 version lacked Cutts compensator, the fins on the barrel, the elaborate rear sight, and the bolt had been simplified eliminating the internal Blish delayed blowback system, but it retained the hammer and firing pin similar to the '28. Later, this was eliminated and it became a "slamfire" style subgun: the bolt had a milled "nib" on the front that struck the primer. This became the M1A1 version.
AKA The "M1 model, variation "A1."
The M1A1 Carbine was the M1 carbine in a collapsable shoulder stock, intended for parachute use. A la' paratroopers.

The "M#A#" style system was used for many items used by the army in WW2.

as far as i know, when i was in, the m1 garand was the ww2 30 06, the m-14 was its replacement, in 308 the m1a1 was the commando/folding stock version of the m1 carbine and the m1a was the civilian designation for the m-14 thats my story and im stickin to it

 

[blackops]

M1 Garand - .30-06
M1A1 - .30 Carbine
M1A - .308

Exactly.

 

[ms6852]

As stated above the M1 garand is 30-06 or the Nato 7.62X63
M1A is 7.62X51mm or the civilian equivalent of the 308
and the M1A1 the 30 carbine or 7.62X33

Tommygunn has it correct. There was a M1A1 in .30 Carbine that many are familiar with, but the Thompson M1A1 is a .45 ACP submachine gun.

+1 For Tommygunn. He is 100% correct.

120mm and it's a smoothbore...oh, not the tank? I think I speak for everyone here by saying you mean M1A not M1A1? Then the M1A is chambered in .308 and the M1 Garand is chambered in 30/06. It is possible to rebarrel the Garand in 308 though, just to add confusion. I forgot what year, but the military went away from using the year of adoption as a model designation and started by using a system of chronilogical adoption. So the first auto loading rifle adopted was Rifle, M1, the first carbine was Carbine, M1 and the first submachinegun was Submachinegun, M1 and the first can opener was Opener, Can, M1 etc. (Not sure about the can opener) Prior example would be Rifle, M1903. M1A is a model by Springfield Armory, Inc (not the government arsenal) and if you are not confused by now...

the m1a1 family

There is no M1A1 family.

M1 means the first model of a weapon after adoption.
A1 means the first modification to it.

In the instance of the M1 Carbine, the first model was the standard M1 carbine.
The M1A1 was the standard M1 carbine but with the addition of a folding stock.
The M2 Carbine was a full-auto version of the M1 with a standard stock.
The M3 Carbine was an M2 with an infrared night vision scope attached.

There is also an M1A1 Abrams tank, but it is not part of any small arms "family.

To confuse things, the Springfield Armory made and "M1A" in 7.62x51 is often referred to as M1A1. There are a couple on Gunbroker right now.

'To confuse things, the Springfield Armory made and "M1A" in 7.62x51 is often referred to as M1A1. There are a couple on Gunbroker right now. '

And to not further confuse things, this poster is refering to the commercial firm of 'Springfield Armory,' not the government arsenal in Springield, MA that made so many fine military firearms over the decades. The commercial Springfield M1A is a semi-auto civilian version of the government's M-14.
