Odd thing shooting tonight. I purchased a couple boxes of 9mm Tul-Ammo to give it a try. I previously shot Tul-Ammo in my AR-15 without any issues, but the PX4 magazines were not a good fit for this ammo. The gun shot it fine, but after loading 10 rounds in my 17 round magazine, the follower would get stuck. I would take the magazine out of the loading device and the rounds would just fall out. A couple of times I had to smack the butt plate of the magazine pretty hard to get the follower to move.
At first I thought it may have been my error in re-assembling the magazines after I cleaned them. But I pulled it apart and verified it was put together correctly. Tried another 10 rounds and got the same thing. This happened with all three of my spare magazines. So I switched to WWB ammo and the problem went away. Something about the coating on that steel case ammo that the PX4 magazines did not like.
Oh well...now I know.
