Historical profile
Developed by Daewoo Precision Industries in the mid-1980s as a domestic pistol to replace the ROK Army's licensed Colt M1911A1.
Adopted in 1989 as the K5; on the US civilian market sold as the DP51 by Daewoo/Lionheart.
Introduces the 'fast action' system: pushing the hammer down with the thumb compresses the spring while keeping the hammer lowered, giving a light, short pull like single action but with the hammer down (passive safety).
