Also, MAC-11=FAIL. MAC-10 is OK, I guess, but without a longer barrel, it's kinda stupid, but at least it fires .45 ACP (or 9mm, I guess, but I've never seen one that does). OTOH, an Uzi is not such a bad Idea in semi, because they can be carried compactly, then extended to function like a rifle. They have the action toward the rear of the gun, and that allows for a longer barrel even in the compact size. Longer barrels extend the functional range, power and accuracy of pistol rounds, so that you can use your favorite pistol round in a rifle configuration and therefore need only one type of ammo. I considered the semiauto Uzi in 9mm, because I have a pistol in 9mm and I like the round, but I decided on the Marlin Camp 9 instead. It's much cheaper, and takes high capacity mags like an Uzi, but it looks like a regular semiauto rifle. I'm still looking for one to buy, though. I expect to pay about $400. Meanwhile, Uzi's cost more than AR 15's!
