Nov. 4, 2008 may not have been good for our 2A rights, but it's been good for my social life. I've taken a different lady to the public range the last three times i've been. (Before you ask, no, none were blood kin)
Need a PISTOL? A carbine isn't as good as a pistol. Need a SHOTGUN? A carbine isn't as good as a shotgun. Need a RIFLE? A carbine isn't as good as a rifle. Don't know what you need? Then you need a CARBINE.
I think they missed the whole idea of the carbine when it came to the M-2 .It would have been a better sub machine gun than what were available then .It had greater velocity and range than the Thompson or the M3A1 Grease Gun plus lighter weight and the ability to carry more ammo at a reduced load weight .
