The CZ P-07 was the first handgun to feature the convertible Omega trigger system. A simplification of the CZ 75's hammer ignition method, the Omega's trigger parts are interlocking in nature, allowing full disassembly and reassembly without the need for gunsmithing experience or tools. The best part of this system is its convertible decocker/safety system. The pistol can be carried cocked and locked or decocked for a double-action first pull of the trigger. It also has forward cocking serrations. This model has an OD Green polymer frame and tritium night sights.
