Just don't think it's any kind of precision instrument... "minute of watermelon" is good from what I've witnessed.
Also - the push/pull technique isn't a good one for a standoff situation. Too much muscle fatigue.
But if you find yourself in a standoff situation with a Serbu Super Shorty - then muscle fatigue is probably rather low on the scale of things to worry about.
Agreed on all three. I'd never consider using my AOW for a real life defensive situation. (zombie apocalypse being the exception)
Wouldn't want to deal with the legalities or what would happen to it while in the evidence room. And can you imagine the headlines....... "Man Kills Intruder With Sawed Off Shotgun, And He'll Actually Be Getting It Back!" The idiot media would have a field day.
