Issues with Partizan PPU 9mm

[bigkracka]

I had some light strikes with a Glock 26 last range trip and I'm wondering if anybody else has experienced this with PPU. Pistol had no issues with WWB.

I reload so I have no experience shooting this brand of ammo in my pistols. I do use it in my AR15 without issue.
Where I have had issue with their 9mm pistol ammo is in reloading their cases. Their primer likes to stick in the pocket, jamming my progressive press. This happens with all cases from time to time but it is so predictable with PPU cases I just throw them out. Something about their primers or the way they put them in [it doesn't look like they crimp them]?
Best,
