Apparently there are some correlations between the M1Carbine and non-corrosive primers, and that is true. But it is not what defines a carbine. As others have posted here a carbine is essentially a shorter, more compact lighter, and/or all of these, long gun (as opposed to a hand gun). Not always all of them, but at least one or more. As far as I know there is no barrel length or overall length that defines it though.
Good to know about the M1 Carbine using non-corrosive primers. I didn't know that. I thought all of the older ammo had corrosive until the early '50's. But it was not what defined a carbine, I did know that.
And no, I don't think the guy is present here. I worked with him many years ago and he professed to know everything and anything about guns. I think he even had 2 or 3.
