Fast Action Trigger System: In a nutshell, here's how it works. A round is chambered and the pistol is cocked. The hammer is pushed forward with a thumb and then engage the ambidextrous safety. When the safety is disengaged, the hammer automatically springs into the cocked position for a single-action press of the trigger. There is no longer the heavy double-action 1st shot to contend with. Trigger pull is consistent from first shot to last. These systems are incorporated in the DAEWOO Fast-Action and Para Ordnance Light DA pistols.
