Originally available in Black Oxide blued chrome steel and electroless nickel plate finishes, it eventually was also offered in stainless steel.

With an excellent 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). 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.
