Quick M1 Carbine questions.

[Jasonsmack]

Is a carbine magazine a single stack format or double stack format?

How wide is the magazine?

I am in search of some magazine springs for a project. I need some fairly narrow springs for my intended purpose.

Thanks.

Double stack,bit more than half an inch wide or so.
