Thanks for the comments guys.
To answer KENNYR's questioning on trappers being
allowed to pack a handguns, the answer is yes and this is somewhat recent.
A lot of people that work most of the year up in northern Canada wether they are are surveyors, drillers and pilots have had real close encounters with bears, all are being refused the right to include a revolver as part of there survival equipment.
I think that people should have right to chose what weapon suits them most for there convenience.
Revolver in a BH206 or AS350 cockpit is a hell of a lot more discreet from passengers eyes than a shotgun
