Ok some posters have asked about the promag magazines and if they are any good. Since it is extremely difficult, if not impossible, to find factory 25 round mags some of us have bought these magazines. Understand that I have no affiliation with this company or any of its employees so I am unbiased. I am going to try and include pics throughout this thread if I can. I bought 5 magazines and decided to review them for others. I tested these magazines on a brand new m&p 1522 using a brand new Nikon P22 scope mounted using a M223 base. It was a balmy 21 degrees here with a wind chill of 11 degrees. The wind was blowing out of the south/ southwest with 20 mph gusts. There was already 2 inches of snow on the ground with a storm coming to allegedly dump 1 to 4 more inches of snow. So needless to say it was cold and I was trying to get this done quickly. I had my 13 year old son with me to help out.
