Can't go wrong with the Lancers or PMAGS in my opinion.
There are some bad mags out there. We got some alluminum mags for the department that were not teflon coated. They would not feed even with ball in our department guns. After that I was able to talk the Chief into P mags despite the higher cost. There are junk mags out there. But your right about Lancer and Pmags being good. So are a lot of GI mags. But stick with the good ones with teflon cloating. Hence why I recommended the Brownells mags. I got 2 mags from C Products for T&E they were the stainless ones. One lasted for a while and did fine. The other one died early from a cracked feed lip. USGI mags work but they are the least durable of the mags mentioned and have the shortest service life.
