Well Hell,
I think my days of plastic follower for duty use is over. Referring to WC mags. I am using WC ETM 8s.
All was running good.... 150 rounds shot and on my third box of 50, I experienced one stuck mag.
I was able to snap a photo of the issue. The follower is side by side with the slide stop inner lobe.
I pushed down on the follower and heard a click and the mag released with ease.
I am able to use moderate thumb pressure and the follower pushed inward at the mark where the slide stop was against.
Another part of me wonders, I have 2-3 years of use (I am guessing)... have I worn out the followers?
I am going to run another test with old CMC PM 8s and newer Check-Mate 8s.
