I really like the Tactical Innovations 25 round steel lip magazines. In my experience, they are more reliable than the other aftermarket magazines available.
I've had my Butler Creek mags for quite a few years now and have never had a single problem with them...for half the price. Whenever the time does come to clean them out because of crud and what not in them (haven't gotten to that point yet and I've been thru thousands), I'll just go buy a couple more new mags.
