in response to OP first post....
My brother inlaw is a DOW officer and tells me you can take as many guns as you want when hunting. you can bring along any pistol or rifle too. You can take any big game animal with a side arm as long as you meet the guidlines of 4" + barrel and 550 ft lbs at 50 yds, and .22 for small game. If you kill a mountain lion with a 22 and you do not have a tag for animal or do have one, you had better be able to prove it attacked you. You can not just shoot one because you thought it might attack you.
As far as concealed carry, it is legal to carry side arms while hunting.... there are no laws stating it is unlawfull.
