The P-09 C Nocturne by CZ USA retains all of the same great features as the original P-09 but adds a wide array of performance enhancing upgrades. The slide is now optics ready and is compatible with direct mounting of Shield and Holosun K footprints. The sights have been upgraded to luminescent 3-dot contrast sights, and the front cocking serrations have been enhanced. Just like the previous models, the P-09 C Nocturne comes standard with interchangeable small, medium, and large backstraps, allowing pistol to conform to a wide array of different hand sizes while retaining the natural point of aim that CZ handguns are known for. One of the P-09 C Nocturne's more notable features is its Omega Trigger System and convertible safety/de-cocker system. Conversion only take a few minutes, and allows the user to carry the pistol de-cocked for a double action first trigger pull, or cocked and locked like a 1911.Features of the CZ P-09 C Nocturne: NEW: Optics ready slideNEW: 3-dot luminescent sightsNEW: Upgraded ergonomicsInterchangeable small, medium, and large back strapsOmega Trigger SystemConvertible safety/de-cocker systemIntegrated 1913 picatinny rail under the barrel CZ-USA P-09 C Nocturne 9mm 3.74" Bbl Optics Ready 15rd Compact Handgun 91660
