This is a question we get asked quite a bit. It seems like some folks don’t particularly care for them, but we like them for quite a few reasons. It’s important to note that all of the reliability testing we’ve ever done on our guns has been shot with PMAGs, including the 7,500 rounds we shot at SHOT Show Range Day on Monday.
From a reliability perspective, we have never had an issue. The real reason we chose PMAGs is actually related to something else about the magazine that people often forget: a big part of the reliable function of a gun is consistent maintenance of your magazines. The PMAG is so simple to disassemble and reassemble so you can regularly clean your magazine. Most malfunctions with a gun start with a magazine issue, so regularly cleaning your mags, especially if they hit the ground, is really important.
The other reason that we like PMAGs is the basepad size. If you run into a malfunction, sometimes the magazine can be difficult to remove, but a PMAG has a nice big, serrated basepad so you can get a good grip to pull it out. This is especially helpful if you have the optional magwell installed and need to do an emergency magazine removal, as you’ll still get adequate purchase to remove the mag.
