The most important reason to pack a sidearm, is, because you want it there. Second most important reason, is because there is stuff that needs to be shot.

Mine is carried daily. The reservations are sovereign nations, and the rules for non band members are different here in MN. You will have to make an effort to find out the rules that tribe has in place, specific to non band members. Try to get it in writing from the law enforcement people in the particular reservation you are on, and do not assume a neighboring band has the same rules.

I avoid foreign countries as much as is humanly possible. Im uninterested in learning or living by their laws. That includes Canada.

Good luck. Hope you are well, Lloyd.

Best,
Ted
