Bear spray.

I can clear 5 bowling pins from the front of a 4x8 sheet of plywood with a .45 from the leather at 7 yards in under 3 seconds when I was younger, still under 4 today. I'm the rare breed of a canadian that shoots IPSC. Even when I know I could get away with it (illegal in canada) I don't bother with pistols. They're heavy, and I've seen the tests and papers. Bear spray is more effective, and it's a lot lighter than any of my guns that aren't going to just make something merely annoyed when shot at.
