How many bullets can a pistol hold?
"Average" is a matter of opinion, and probably impossible to
define. In regards to "regular" magazines, some 1911 style .45
pistol magazines hold 7 cartridges, some hold 8. Some 9mm pistol
magazines hold 7 or 8, some hold as many as 16, many hold 10. Some
.40 caliber pistol magazines hold 8 or 10, some hold 15. Then there
are other calibers, and they all hold various numbers. During the
notorious assault weapons ban, newly manufactured magazines in the
U.S. were limited to 10 rounds, and because of that, some people
consider 10 rounds to be average or they consider more than 10
rounds to be "hi capacity," but neither one of those is really
correct.
