The PF9 is simple and accurate enough. But it lacks second strike capability. It hasn't been an issue, but I think about that one feature.
Craptastic accuracy, Massive trigger pull, since it weighs next to nothing the kick will surprise you, little difficult to hang on to, and you will learn a new term "Trigger Slap" and you will learn to respect it (little dab of sports cream and some ice will fix that swelling).
