Out of what I have, I would pick my xdm in .45 acp.
I do not think there is a good handgun for dealing with bears, but I got the xdm with the idea that it would be a good thing to take along next time I was in bear country.
I think a good handgun for dealing with bears would ba Semi Auto 12 gauge Pistol...
I am thinking 3 1/2, cause I can run anything I need to through it...3" or 3 1/2" Magnum.
My 3 1/2" Mag knocks the PI$$ out of me. Can not imagine a pistol version but I want one.......................
after he made you his lunchOf what I own, I would have to go with the Keltec PU16. 30rnds of 223. I think it would stop a bear.
