I suggest looking at the FNX-9 or CZ P-07. I like that they are capable of condition 1 (unlike the Beretta). I like that the safeties are frame mounted instead of slide mounted.
But, yup the fit and finish of the PX4s are really good for the price. If you don't mind the location of the safety and the lack of condition 1. I'm sure you will like it.
