#3 Baseball bat
If I had to take 3 and I'm betting my situation would invoke close quarters combat I would choose these 3 (may JMB forgive me)
A Kriss rifle and a Glock 21 because they both take the same magazines and some can be had with a 30rd capacity. Now I'm not a Glock fan by any means but I do envy their magazine capacity.
And this beautiful shotgun here
