DAMMIT! I hate it when I close the window instead of hitting submit after previewing a post...
Let's try this again...
1) Bowling for Columbine is a SATIRICAL piece. 99.475% of the entire film is fabricated. Michael Moore even admits this fact. He just wanted to get everyone's panty's in a bunch and he did a brilliant job of doing so.
2) Weapons only kill in the hands of those who already intend to kill - accidents aside. If I wanted someone dead I could just as easily kill them with a pencil, an icesickle (not in Arizona), or my bare hands that were trained to kill by the USMC. I don't have any reason or compunction to kill anyone though, so I haven't.
3) To the question at hand... I'd go for the Sig Sauer. It has a more sturdy design and a smoother action and I've never heard of one jamming, unlike some stories of Glocks I have heard. For smaller caliber hand guns I'd go with a Walther PPK .38cal. They are compact, balanced and smooth as glass in their action.
