There are also 10-round, single-stack 9mm Glock 48/43X magazines. The 48/43X magazine will not work in the Ruger PC, it is too skinny. Don’t buy those for the Ruger PC.
As was stated above by
@dogtown tom, all of the OEM Glock double stack 9mm magazines from the 19,17, 26 will work in 10 round configurations, as well as in standard capacity sizes (and extended 9mm double stacks like my 33 rounders), with the Glock magwell insert installed.
OP: Buy a Rigid toolbox and some cut-to-fit Kaisen foam, and you have a nice little inconspicuous carry case for your PC.
