Hamid, you did not specify the CZ for comparison to the CZ Shadow Orange. The Shadow 2 Orange features new aluminum grip panels, the main parts of the CZ Shadow 2 Orange are hand fitted for exacting precision, the barrel is polished to improve accuracy and now sports a bushing for added stability. The trigger is tuned for a smooth, crisp release and offers a very quick reset. Also, the CZ Shadow 2 Orange is equipped with a competition hammer and an adjustable aluminum magazine release catch. The magazine has an aluminum base, and an enlarged left safety catch to provide a more secure surface.
