Kahr K series

The Kahr K series is a series of semi-automatic pistols manufactured by Kahr Arms. The original weapon in the series, the K9, was introduced in 1995 and features a double action only (DAO) trigger mechanism with a Locked breech recoil operated action. It was intended to address the police backup / off duty and civilian concealed carry markets.
With a reputation for both quality of construction and reliability since its introduction the pistol has remained popular with both the police and civilian markets. In 1998 it was approved for off duty and backup carry by the New York City Police Department (NYPD) but as of December 2011, the Kahr K9 is no longer authorized by the NYPD as Kahr Arms was not able to increase the trigger pull to the NYPD specifications. Since its introduction the pistol’s design and construction have undergone a number of improvements including slightly increased chamber dimensions and the use of a Teflon electroless nickel composite material for some of the internal moving parts which improved reliability.
Options offered with the K9 include tritium night sights, and wood Hogue grips. The Elite version of the pistol offers a polished feed ramp, polished and deburred slide, beveled magazine well, and enlarged trigger with a smoother action.
