This concludes the 2000 round challenge. I did lube the new stealth levers when I installed them at round count 1992. I didn't lube anything else on the gun.
I had 4 stoppages with my PX4, the first two caused by a stuck magazine follower. That issue stopped when I degreased the mags. The other two were user induced, with a failure to feed brought on by a failed slide lock reload where I didn't get the mag fully inserted into the gun before I depressed the lever. The slide stripped off a round, but the extractor didn't pick it up and it got stuck to the left of the feed ramp. The other was a failure of the slide to lock on an empty mag, caused by improper grip when I was shooting SHO.
I also dry practiced with this gun extensively since I started the test last November. I would guess I've got thousands of draws and reloads and several thousand double action trigger presses on this gun. There is some holster and finish wear on the slide and the magazine well has a nice grove worn into it where the the square face of the mag bashes into the magwell if I miss a reload.
Here are the obligatory filthy pics! Note the lube still visible on the locking block, barrel and slide. The Lucas Red n' Tacky grease is a great product.

Slide wear.
I have to say that I am very glad I purchased this gun. I'm a huge fan of 92's and the PX4 was supposed to be just a winter diversion, but it's so shootable and likeable that I'm using it as my my current competition gun.
