I can't speak for the Krytac in particular but as of late I haven't had allot of mag issues with just the fairly inexpensive brands of mags. I think the ones I'm running right now are MAG branded, I picked up used from another forum. But I've run them in my old CA's, TM's, and a newer APS without any real issues to speak of. Compared to my old G&P midcaps they are pretty close, not quite as good as my old TM 68 round mags but still quite good for the price.
Take care!
Luke
