Like RickB, I've spoken to the Lionheart guys, in my case at gun shows in the Seattle area.
It is a real Daewoo. The firearms part of the company has changed names but it is the same company that makes the pistols and rifles for the S. Korean military. I like the new versions and would like to own one.
It is not just a copy of an old S&W. This gun has the same interesting hammer system that the S. Koreans adopted. I've used it in the .40 version (years back, when it was called Daewoo) and it works.
1) Load the weapon, ending up with round in chamber, slide forward, and hammer cocked.
2) Push the hammer forward until it is almost fully down. The trigger is not in the fully cocked rearward position.
3) Carry it until needed, then draw, aim, and pull back though a very light but long trigger pull. While the trigger is being pulled, the hammer will snap back to full cock, then release when the trigger is fully back.
4) Fire rounds as desired with normal short and light single-action trigger pull.
5) When desiring to return pistol to holster, go back to Step (2).
