New Go-to Sidearm Hk Usp9

So I decided to buy a USP9 in order to have a full size military style pistol. I also have a Glock 33, but that's a concealed carry weapon, and a good one, too.

I now basically have all I need for most needs: A 5.56 rifle, a shotgun, a hunting rifle i.e. Mosin M38, the HK USP9, and a Glock 33 .

What are your personal go-to weapons? I only bought guns I felt were useful and fit a true purpose in a disaster...but also to have only as much as I could reasonably transport quickly in an emergency.
