I shot my PX4CC for the first time in a while this past weekend.
Wow.
I almost forgot how nice it shoots. I put one of the Langdon optimized performance trigger bars in mine. Really tore through some rapid doubletaps. Kept the hits in a pretty coherent pattern. I shot my 92F side by side. The PX4CC shot just as well.
It always feels a little bulky when I carry it. The slide is just... fat. But it has to be one of the nicest shooting pistols out there, regardless of size. I've never shot a full sized PX4. I imagine it's excellent.
