No issues.
I cleaned and lubed it after my 2/28 range trip. Put about 100 rounds through it. Didn't clean it or relube it, sat for 2 weeks... then 60+ rounds. Didn't clean or relube it, sat for another week... then 100+ rounds. Mix of 115 and 124 FMJ.
I realize PF is the land of the 2000-round challenge and that's not blowing anyone's mind. But I'd say it bodes well for the gun's reliability. I'll probably shoot one more time before I finish writing the review on my blog.
Overall, my shooting impressions haven't changed a whole lot in the past few hundred rounds. It offers a very direct, visceral shooting experience. Though, as @
pangloss pointed out, the mag release does dig into your middle-finger tip on your strong hand. I'm finding I notice that a bit more, now. Certainly not a deal breaker, but it's mildly annoying. Hopefully they'll offer a more low profile button, at some point. So far, I have not had any of the "auto forward" slide release situations Pangloss encountered.
