You won't be spraying to kill the zombies if you know what is good for you, so that is 10-30 shots in a single magazine, which when aimed right count as at least 15 kills.
A shotgun does not even carry ten (if I'm not mistaken), and the shells are not interchangeable between other types of firearms.
An MP5 with 9X19 parabellum would work with both an mp5 and glock 17 (as would a .40 and 10mm) and those are the two types of firearms I would carry. The ammunition and firearms are both very light, and would be much easier to carry around during action than a shotgun and a box of shells.
