This is a good choice, likewise Taurus I prefer taurus, but this is a personal thing.
I suggest that in the realm of reliability and usability, battlefield experience is probably the most severe test of a firearm. Military type firearms are usually engineered so that even the dimmer lights can work them (My translation of the AK-47 manual stresses that ammunition is not to be thrown in fires) They have proven reliability , and adequate stopping power. My current Uzi fits all of my criteria of an ideal home defense weapon except one (cost).
LOL- That would make a good 'Surgeon General's Warning" for ammo boxes!
Your UZI sounds like a potent package -- lighter than a shotgun, with more range. But you can't hunt birds with it! (Can you?)
