So, I went to the range yesterday to play with my new xd 9. Take note that I live in Cali so any mag past 10 rounds is a big no no. The range master says I can shoot the xd with 15 or 16 rounds of 9mm with a 357 (xd I guess) mag. He actually shoved 16 rounds of 9's into that mag, the last two rounds using a mag loader. Has anybody tried it ? Is it legal ? (for Cali that is) .
