The Daewoo K5 is a 9 mm semi-automatic pistol produced by Daewoo Precision Industries of South Korea. It is a compact, lightweight pistol with an unconventional trigger mechanism called "fast action". The frame is composed of an aluminum alloy with a matte finish, while the slide is of blued steel.
K5 was produced in 1989. It is recoil operated and uses a conventional Browning-type locking system. It is mostly carried by Commissioned Officers in the Republic of Korea Armed Forces
The "fast action" trigger mechanism allows the hammer to be decocked while still keeping the mainspring compressed. A light pull on the trigger causes the hammer to flick back, after which the pistol would behave in conventional single-action (SA) mode.
The pistol can also be fired in conventional single- and double-action (DA) modes. The "fast action" mode allows the trigger travel of DA mode and the trigger weight of SA mode. This allows a more accurate first shot due to the lighter weight of the trigger. It is also safer due to the longer trigger travel required to fire the pistol. The factory magazines hold 13-rounds. Smith & Wesson 59-series magazines are compatible with the DP51 but will protrude slightly.
The pistol also has an ambidextrous safety and 3-dot sights. It is also equipped with a firing pin block which (as its name implies) blocks the firing pin from moving forward unless the trigger is pulled.
The known variants of the K5 are the DP-51, the DP-51C and the DH-40.
The DP-51 is the civilian version of the K5, while the DP-51C is the compact version of the DP-51. The DH-40 is chambered with the .40 S&W.
