Re: Polar bear defensive handgun
Just another thought. When I think of a defensive weapon I think of two main things; familiarity with the weapon and the ability to make the shot. If you are shooting 10,000 rds a year competitively with your glocks its pretty safe to say that both of those aspects should be covered.
Now there isn't much that would stand up to a hit from a big bore revolver, but then again, you have to hit it....and the 10mm with a heavy bullet can pack a punch.
I personally would feel more comfortable and confident with a weapon that I have spent countless hours behind than that of one that I was unfamiliar with. Theres a big difference in form, function and recoil of a magnum revolver compared to the familiar glock.
Either way, Stay Safe up there.
