HottAK47 - that was an excellent article and I completely agree that using anything full-auto probably isn't a great idea for a home defense gun.
Heck, I was on a jury about 3 years ago where they tried to convict a guy in a HD situation because he had shot the intruder 4 times with a .25 caliber pistol. The last shot went in sideways and the prosecutor pulled the same crap about it being in the back...
Having said that, I would use a suppressor on an HD gun - purely because I like my ability to hear. It's the same reason I wear muffs at the range.
