M1 Garand Trigger

[Kaydee]

The trigger information for my serial Number M1 Garand says the trigger should be C46020, Type 2, November/1940 to December/1957, serial Numbers 80001 - 6100500, No tooling hole. No markings. Please click on the link Dropbox - Sign in and view the trigger. Is the hole in the trigger considered a tooling hole??? If it is not can you supply me with an image of a trigger with a tooling hole??

Bob,
Very good information but I still do not know what a tooling hole is. I see in the definitions that there are two Garand triggers and one has a large hole. Is that what is meant by a tooling hole? I see the hole was dropped in 1941.
I have also just discovered my trigger has a S 72 or S /2 on the side of Trigger. I have not read anything about this. I will try and attach an image. Can you give me any information?

The hole doesn't seem to have any obvious purpose... some people think it was to mount it in the fixture for machining, but nobody really knows. Maybe it was a simple lightening hole when every ounce helped reduce the weight.

Bob,
You didn't say anything about the image that shows S 72 or S /2 or S 12. I have never seen any mention of this. It is not stamped it is raised.
Check out the image!!

Yeah, they are marks in the forging dies, well known and also indecipherable. Commonly found on bullet guides. Like the random inspection marks found on the barrel, they are just more examples that we don't know everything about the M1, even after 30 years.

Thanks Bob for the information. I thought maybe they would tell me who and when the trigger was made.

Thanks Bob for the information. I thought maybe they would tell me who and when the trigger was made.

If it helps, those forging marks on triggers and bullet guides were apparently used only during WWII. They are not seen in rifles produced after WWII.
