It extracts every other case, right? So the problem is intermittent. Hyper-function? The action is working faster than the normal speed for extractor to do its job. Have you changed ammo or is the recoil guide spring now too weak?
Compare the lips of and old mag to your new after-market Pro-mags. I'm wondering if they're causing underfunction (opposite of hyper-function). The mag lips may be so high as to cause drag. Alternatively, the spring tension of the mag spring may be too strong and thus it slows down the rearward motion of the slide. This is one reason why I don't like aftermarket magazines. Unless they build them to factory specs, they may limit the range of ammo or conditions under which the gun will function reliably.
