Glock standard mags:

9mm - 17 rnds

.40 S&W and 10mm - 15 rnds

.45 ACP - 13 rnds

.357 sig - 15 rnds

31 - 33 round extended mags are also very common outside restricted states.

Most semi auto pistols have the same or varying capacity depending on weapon size, full, mid, compact, etc. and magazine type, single vs. double stack.

My FNX-40 came standard with 3x 14 round mags. They make a variant with 10 rnd mags called the CA variant.
