When I found some of these Promag 32 round magazines available, I initially only purchased a couple to try, and was skeptical. Whereas the M&P 15-22 looks a lot like an AR-15, using the longer Promag magazine gives the M&P 15-22 a more AK-47 look to my eye.

HereвЂ™s a photo of the stock 25 round M&P 15-22 magazine next to the larger Promag 32 round magazine for the M&P 15-22: The stock M&P 15-22 magazine is slightly more expensive ($16.99 vs. As I began searching and researching, I discovered 3rd party magazine manufacturer Promag had recently come out with 32 round magazines for the M&P 15-22: Of course, I wanted to get some extra magazines for the new rifle вЂ“ but practically overnight M&P 15-22 magazines all but disappeared in a panic driven marketplace. My thought behind doing so was that ammo might be scarce, expensive or both (which happened unfortunatelyвЂ¦and far worse than I expected) so IвЂ™d shoot my 15-22 more and not loose touch with the skills IвЂ™d paid mightily for in both time and cash to develop.

I bought my 2nd one in December of 2012 вЂ“ not long after the Sandy Hood tragedy and the subsequent calls for banning guns and high capacity magazines. But it works.Fans of ThruMyLens know I absolutely love my M&P 15-22 ( previously reviewed) вЂ“ in fact, I have two of them. Specifications: ProMag 31 Round Glock Magazine But if youвЂ™re looking for something to stick in your bug-out bag, youвЂ™ll want to wait until the legitimate Glock magazines are back in stock. This is a range toy that keeps me from having to reload so often. In the end, this isnвЂ™t something that I would trust my life to. It works exactly as advertised, and I couldnвЂ™t get it to malfunction. Once the magazine is in the gun, though, you wonвЂ™t notice a difference. False advertising? Or perhaps someone just mixed up in the labeling department. ThatвЂ™s an interesting quirk, though: these magazines are clearly marked on the packaging as вЂњ32 roundвЂќ magazines, but the mag itself is only labeled for 31 (and holds exactly 31). Which is already a step up over the Korean PW Arms Glock magazines, which I was unable to load to capacity. Well, you can actually load all 31 rounds into the magazine without excessive force. So, the magazine is cheaply made and feels like it contains less plastic than a Barbie doll. Not only are these flaps annoying visually, they could potentially lead to an issue with feeding ammo into the gun. Where Glock magazines would have been clean and precise, the ProMag lips have residual flaps where the two halves of the injection molding machine came together. That lack of quality shows through, especially around the feed lips. Instead, they went with something thatвЂ™s just south of Lego standards. And not the nice, sturdy plastic that Glock uses. The ProMag magazine, on the other hand, is 100% plastic. Original Glock mags have a metal insert that keeps them from breaking or bursting. But on the inside, where it counts, there are some issues. On the outside, and in the packaging, the magazine looks like just any other Glock magazine. But in this case, there are some noticeable differences. In some cases, their magazines are indistinguishable, or actually better than the factory magazines. ProMag makes aftermarket magazines for just about every firearm out there, from the Sig P226 to the Glock 19.
