Who packs a handgun while hunting? Or leaves one in the tent/camp? What caliber, barrel length do you like?

The reason I ask is because I am hunting in the Absaroka-Beartooth wilderness in September. This area has a high number of grizzly and black bears. Running into a grizz while hunting doesn't concearn me. However having a bear encounter while dressing out an elk does. Everybody with blood on them, and the rifle leaning against a tree sort of thing. Also I thought that keeping a pistol in the tent...to use if you have to go to the latrine in the middle of the night might be re-assureing. Don't think that I am perranoid (sp) about bears. I just like to be prepaired.

I was thinking of a Taurus Tracker in .41 mag or .44 spl Titanium with either a 2" or 4" barrel.
