CZs are interesting. I cannot for the life of me shoot better with anything than a CZ. It makes me look godlike, when in reality I am an average to decent shooter.
Because of this, I am willing to overlook a few things. And number one of those is finish. They are not finished well, in all the cases I have seen. Now some of the custom guns are, and even the regular models have visually appealing shapes to me, but the finish is often lacking. The fit is usually excellent, slide to frame, barrel to slide, but the finish, especially internally, is just not. I overlook it because the performance is usually still good.
Know the status of your weapon
Keep your muzzle oriented so that no one will be hurt if the firearm discharges
Keep your finger off the trigger until you have an adequate sight picture
Maintain situational awareness
