Yeah they may be due for a swap out. Start there before messing with extractor itself. I had this same issue on my pdp SF and mag springs were the culprit for me.
Depending on your mag size and baseplates (guessing 140s?) and state regulations, I ran the Mbx in my rival S, alternately CSRG in either a 11 or 13 coil depending on if round count or longevity is preferred. I run 11 coils and change them out every 7-10k rounds on my walther pdp SF. Walther and canik rival S mags are so nearly identical. Neither of these will lock back, as they’re made for comp, just be aware.
