So Rap4 plan to bring out the 30 rnd (15+15) dmag in the "next month" - which is rap4 for six months. Still, it's good to know it's actually in the works since a dual stack thirty more or less makes up for the inconvenience of having to switch. The smaller mags will be fine for FS rounds though. The 30 will be looong, but just turn it sideways if you gotta go prone
Also, the 468 accepts scarab mags if you don't go with the dmag magwell. Looks like a great platform and after some umming and ahhing is probably my current choice - I'd change my vote if I could.
 ok scratch that. Having to recock after every mag is a dealbreaker. I'm back to the MKP.
