I recently go a hold of some of the new Magpul polymer magazines dubbed "PMags". These magazines are made out of an extremely lightweight, yet strong polymer and holds 30 rounds. PMags were designed to be mass produced quickly without leaving quality behind.

One of the first things you'll notice about a PMag is the shape and texture. These magazines have slightly less curvature than their G.I. issue counterparts and are textured differently as well. The strength is unbelievable; there's no way I'm breaking one of these. One person on YouTube has actually ran over a fully loaded PMag with a Chevy truck, then loaded the magazine, and fired every round without a hitch. That's got to say something about its strength.

Hand loading rounds into the magazine is much easier than with standard G.I. issue mags. You don't have to put nearly as much pressure on the spring to get it to compress. With the G.I. mags, the spring is fairly strong and it can get tiresome or annoying after loading hundreds of rounds. I also like the base of the magazine; it makes it easier to get a good grasp for removal/reloading purposes.

I haven't fired any rounds out of these new PMags since I haven't been to the range yet. However, I beleive they perform flawlessly, at least that's what many other people in the AR 15 community have observed as well. With an internet price of about $13-15, PMags are fairly cheap to stock up on and a definite buy.
