Here is a stupid question:
What does the "P" in PMAG stand for? Is it just "polymer" or are there some other bells and whistles that make it a "PMAG"?
I bought a few polymer 30 round mags when I got my Rock River last month. The price was right, and they work great. The salesman said that I could end up with feed issues if I put more than 28 rounds in them. I am hard-headed and wanted to see for myself so I put the full 30 round in. Still no problems.
They were sold out of "PMAGS" (meaning the box with "PMAGs" on it was empty), so I have not even seen one. Can someone explain what the hoopla is about and where the extra money goes?
The follower is a better design than issue GI mags. In fact you could buy the Magpul followers before you could buy the Pmags. Lot's of people upgraded their standard GI mags that way.
You can choose between 2 kinds of springs (stainless and something else) different colors (black, olive, dark earth and tan) standard floor plates or ranger plates and an optional clear window that gives you an idea of round count. The dust covers come standard. The covers also let you keep the mag loaded for long periods of time without "lip creep" which can cause reliability issues with some GI mags.
They come in both 30 rounds and 20 round versions. They are designed to be reliable fully loaded. My 30 rounders will work just fine with 31 rounds loaded.
The biggest thing for me is they are quite obviously much more rugged. GI mags were built to be disposable for the most part. These things are not.
Most of mine are just plane jane in black. I have maybe a thousand rounds thru one of them without a hitch.
I didn't start out this way but I'm to the point now that if I had to choose between a Pmag and a GI mag to bet my life on I would bet on the Pmag.
YMMV
