I understand that there are generally two major manufacturers of 10rd. magazines for the M1 Carbine. I've heard that one brand keeps the bolt open after the last round is fired and the other brand doesn't. Can anyone clarify which brand is which? Thanks.

anyone?

Any mag with a last shot bolt stop will stop on the last round.

Any mag with a last shot bolt stop will stop on the last round. Um, yeah I kinda got that. I am asking if anyone knows what brands have them and what brands don't?

Here's a M1 carbine magazine FAQ but doesn't mention the 10 rounders.
