I have a few gen2 and gen3 with and without Windows and they all seem much better than my gi surplus mags, the followers on the gen3 are flawless with a stopper to prevent over loading the mag, It's a positive stop on that 30th round, both followers are vertually un tipable with a small advantage for the gen 3. I went to a gun show a few weeks ago and pmags were $50-$100 each, a few days later I had reciever a few from midwayusa.com for $13 each for gen2 and $15 for gen3. Be patient and don't encourage the dealers asking panic prices, get on a backorder list and you will get them and still have your dignity. Hope this was helpfull.
