Got my 2 new mags today, they look good, the quality of the polishing is not the same as the previous mags but still pretty good. The follower is pretty tight at the top but I expect it will break in with a few times loading and unloading. The baseplate is super tight and really hard to get off without some work, definitely much rougher with this batchmbut again, it will probably improve over time. The locking plate one one of them does not pop completely thru the hole, I will swap parts around between macs and seeif I can get it working better, if not I will either return that one or open up the baseplate hole slightly.
I think they will work fine but the only way to know is to take a trip to the range, if I have any problems I will definitely let you all know.
