The Thompson was first made in the early '20's, but I don't know if it was called the M1 then. Maybe ST is correct in that it was named the M1 when WWII broke out

(Something I didn't know until I was reading up on the Thompson a short while ago. It could be switched to "semi-auto"

. Why don't we ever see this mode being used in all those movies etc etc.) ???
By the way, who makes the 'small' M1 carbine? (I could look it up, but then I'd have to move, wouldn't I....

)
And.......was the "automatic" version of the M1 Carbine (ala Korea) called the M2??
