I just put the thousandth round through my PX4 .40 Type F on Friday, with zero failures to feed. I used Federal Champion, CCI, Federal American Eagle, Federal Hydra-Shok, as well as about 75 old .40s that had been sitting in my grandfather's ammo can for about eight years. They were rusted and literally built up with corrosion that had to be brushed off before they would fit into the magazines. I used them specifically to test how the gun handled dirty ammo. It fed this filthy, rusty ammo that had been stored in damp conditions just as if it was the Federal Premium.

I love this gun. My brother has about 2,000 rounds through his Glock 22 and has only shot about 100 through my PX4 and shoots more accurately with it.
