My apc9k came with the glock mag lower.
Liked it but got the recently released aluminum lower that takes the b&t mags. The apc9 pro I just got takes standard B&T mags.
Magblock.com sells the 10/30 piece. Im actually in my woods shooting it now. Epoxies baseplate rendered it permanently. I'm going to get them cerakoted black to hide the insert . KCI makes steel reinforced B&T mags which are $20 on gunmagwarehouse.com. have a connection to get them shipped into MA.
It's gay but whatever. Both guns are 100% ma compliant (as currently defined)
