The HK VP9 Tactical Optic Ready stands out with its 4.7” hammer-forged barrel with threaded muzzle and suppressor-height tritium sights. These sights provide a lower 1/3 co-witness through the window of a red dot sight while remaining visible over the top of most suppressors. Rear sight with serrations gives a cleaner, black sight. High-contrast color tritium front sight for fast day or night acquisition. Additionally, the HK VP9 Tactical Optic Ready model includes an optics cut that, when combined with one of five available adapter plates, accepts most popular red dot sights. Just add the appropriate suppressor and/or optic with no additional modifications needed.
