Seriously, John, just relax, take that bad boy to the range and shoot the crap out of it. If you use good shooting techniques (grip, trigger control, sight alignment, breathing, concentration) you will be thrilled with your PCR's accuracy. That's why we practice, right?
You seem relatively new to CZ's so I recommend finding a good indoor range with a training program to develop your skills. Age is no excuse. I'm 57, my eyesight sucks from staring at computer screens for the last 20 years, wear glasses and enjoy shooting pistols and rifles just as much as I ever have. It's a challenge for me but when I absolutely nail a target, it's extremely gratifying to know that I still can do it almost as well as when I was 27.
Have fun and give us a range report with some pics!
