My hat really goes off to the marketing dudes at Magpul. Seriously, they make a Glock Magazine that is cheaper than an OEM one, even though there is a hiccup in the process they are out in the wild and working fine. Now they release a PMAG 15 GL9 for the Glock 19 and an "L-Plate" which is a tough base plate add-on to the Glock PMAG's. Genius!
