Target practice with a few different brand pellet's first. I bought 3 different styles on pellets. One shoots extremely true. One is several inches off target and one seldom even hits the target.
I've got one or two CZ's and while I absolutely love my Rami and shoot it fantastically, the PCR shoots just as well, conceals better for some reason and holds more rounds. Get the P-01 if you find one of those also. There's not enough difference between the PCR and the P-01 to choose one over...
My mother and my aunt are about as far from avid gun enthusiast as you could humanly possibly get and when I let them shoot a couple PX4's I had they looked like it was their primary weapon. Super super smooth guns.
When I travel I keep a P-09 by my knee in case of cat jacking scenarios. I keep a compact or sub compact if I am going to be out of the truck for a while. Then I keep my LCP for running into gas stations where I just need to slip something in the pocket really quick and easy.
