Assuming you mean the PPS... My younger brother has the PPS chambered in .40 S&W and likes it a lot. I don't think he's ever had a failure in the past ~2 years. It conceals well in a Crossbreed SuperTuck since it's thin.
I've fired 1-2 magazines through it, and wasn't entirely impressed with how it handled - I'm used to double-stack grips (S&W Sigma, SA XD, Glock 22, etc.) and the PPS was uncomfortable for me to hold. But that's all dependent on the user, of course.
