So, picked up a new 9mm M&P Shield today. Was loading the magazines to break them in a bit and for the life of me, couldn't get more than 6 rounds into the 8 round mag. I questioned how stupid I was and wondering if this was the last straw to make me hit the gym. Unloaded and loaded a few times, 6 was it. Gave up, grabbed the 7 round mag, and filled to capacity no problem. At this point I'm scratching my head. Popped open the magazine and low and behold there was a second follower jammed in there under the first. Reassembled and no issues filling to 8 now. Figured you'd get a laugh out of it and hey, at least I have a spare follower now.
