I agree. My PF9 gave me no trouble when I had it, but was not nearly as smooth as the CM9. I primarily shoot glocks, so when shooting fast I caught my self a couple of times not letting out enough for reset. That's just me needing more time with it.
LOL! I posted from my phone, got annoyed of typing on my iPhone, and switched to my computer. Figures someone would catch it and quote it before I edited it!
I had a PF9 before too, and I could shoot it, and relatively accurately, but it was awful both to shoot and in how it recoiled. Between the thin grip and lots of less than smoothed out edges, it was a little harsh on the hands.
