All this talk on auto's reminded me of the first full auto I shot, my buddies Mac-10. Held onto the front strap and pulled the trigger, what a let down. I could have done better at hitting the target with a slingshot! Blew my brass into a bunch of scrap, the Uzi on full auto will do the same to the brass. Now the MP-40 was fun to shoot, not too accurate compared to a 1928. I have found that just about any open bolt will play havoc with the brass. I see that an MP-40 9MM pistol is in country, IMHO unless a person can SBR just a heavy waster of ammo.
