At least keep one mag unshot at all times. Archerandshooter and I always have about 150 rounds per handgun in the house. If I can't shoot all the bad guys in a home invasion with 600 rounds of ammo (I'm not counting the Sig Trailside's .22 box of 500 here) then I deserve to be shot, LOL
But no, never go home unarmed. Handguns make remarkably bad throwing weapons, which is all they're good for if you dont' have bullets.
