These three new 9mm PMAG D-50s are designed for your Glock, MP5, and PCC. Including all of the features found in Magpul’s previous drum magazines, the PMAG D-50 GL9– GLOCK, PMAG D-50 MP — HK94/MP5, and the PMAG D-50 GL-9 – PCC put 50 rounds of reliably-fed ammunition right in your hands.

Well, I guess after whining that these had been delayed so long, I need to buy one.
I’m still baffled that different designs are needed for PCC vs handgun. I’d say it’s BS but it looks like X-Products has the same problem. I’d really like to know the details behind the issue.

That is curious. The 33-round stick Mag works fine in my PCC but was designed for the G18.

Same here – the 33 rnd Glock (and even the cheap Korean knock-offs and the crappy ETS stuff) mags run like a champ in mine.
If I had to guess, I would say the dynamics of a handgun slide vs blowback bolt in a carbine relative to how the next round is presented by the mag has something to do with it. Maybe a speed thing and the drum is slower? Maybe a recoil issue with the handgun snapping back and forth vs a more stable PCC?
