T,
My frame of reference stops with the std "Power Mag" as those worked just fine in my gun.
In fact, I know more than one old school IPSC shooter who has been running the same set of 6 or 7 Power Mags forever. Every so often, the check to see if the lips have spread when the mag is loaded. If they have, they get a rubber mallet and pound them back into "spec".
