so after messing with the accurate mag, arc, aics singe stack, and aics AW, the AW will have the most reliability if the mag has any kind of upward pressure. bc of the lugs located in the 12/6 o'clock position, the bottom lug will come in contact with the feed lips on single stack mags. looks like the only thing that I'll have to do is file a little bevel on the feeding rear part of the mag follower. just FYI
