Hi Seth, yes sir, this will also accept the 15rd magazines, they are the same physical size as the 10 rounders.
The 10rd version is sold for those who live in restricted states, but will also accept larger capacity mags.
Stay safe & have a great day!

Hi Seth and welcome. Yes Sir. The 15rd magazines are the same physical size as the 10rd magazines which are just internally blocked to hold 10rds for sale in capacity restricted States. Cheers, stay safe and enjoy!
