Just got MPX gen 1 20 rd mags at gunmagwarehouse for 12.99, and some P365 mags for thirty seven bucks. They had a real deal on MPX 3 packs, but all sold out. P239 9mm mags for eight bucks...but also sold out. Holiday sale. It's going fast. (I don't work there).

Thanks. I run Gen 1 mags in my Gen 2 MPX without a hiccup. Nice deal.
