The new CAS (CANiK Advanced Sight System) is a variant of the outstanding and award-winning sub-compact size, concealed carry pistols that incorporates two important novel features. First, CAS variants come with integrated patented Metrolight® FT Bullseye, a very low-profile fiber-tritium optical sight, which enables shooters to engage targets instantly and accurately in all lighting conditions with no batteries needed. This integrated sight further streamlines the TP9 SUB ELITE’s snag-free design. Moreover, CAS’s unique arrangement allows shooters to use FT Bullseye and iron sights (included in the package) in tandem if preferred. Secondly, a new flat-faced, diamond-cut trigger, which breaks at 90 degrees, offers very short pre-travel and reset distances, thus allows very rapid and accurate follow-up shots. All in all, with the superior CAS variants, CANiK TP 9 SUB ELITE CAS continues to define the standards for concealed carry home/self-defense pistols.
