Just received a Beta 13 round mag from MDT. These mags are a double stack single feed like the 10 rounders they released last year. I have ran the 10 and they are amazing. I expect the same from the 13 rounders. In the picture below to 10 rounders in on the right AI in the middle and 13 rounder on left. In my opion with these two size mags you can shoot any PRS match and not have to worry about mag extensions or 5 rounders. Will be running them this weekend at Tactical Teachers clinic. If you want to try them out hit me up for my extra one.
