The brass on this gun comes out filthy

Never had an issue with my CX4. It functioned perfectly with any ammo I ran through it, from my bunny fart hand loads to 124 grain +P loads. It is a simple blowback design and pretty easy to disassemble. I would remove the bolt assembly and clean it, then do a close visual inspection of the extractor before putting it back together.
