Recently I purchased a CZ-27. It has the fnh code, and has a blue finish. The grips show the CZ logo. I don't understand why this would have the fnh code and the logo on the grip, it seems like the logo would defeat the purpose of have the code stamped on it. My pistol is in the serial number range of 3819xx. It has a waffenampt on right side of frame, and on top of slide has the nazi eagle followed by the serial number. Any thought on this one?
