Built on a proven short-recoil, Browning-type tilting barrel system, the DP51 balances robust construction with a lighter alloy frame. The forged 4140 steel slide and forged 4150 steel barrel provide strength where it matters, while the 7075-T6 aluminum alloy frame keeps weight manageable in a full-size profile.
The trigger system is DA/SA with Fast Action (Triple-Action), giving users an additional mode alongside traditional double-action and single-action operation. A spurred external hammer, manual frame safety, and firing pin block round out the control and safety features.
Sighting is straightforward with fixed 3-dot sights (fixed dot front and fixed 2-dot rear), and the slide wears rear vertical serrations for traction. Black checkered polymer grips with Daewoo logo medallions offer a secure hold.
This pistol is import-marked B-WEST TUCSON, AZ and MADE IN KOREA, with the barrel marked "9MM PARA." It carries a 13+1 capacity and uses a push-button magazine release. It does not have an accessory rail on the dust cover and is known to be compatible with S&W 59-series magazines, which protrude slightly.
