Isn't the Kahr a double action only pistol? If so, that is the design of the gun. U can never make it into a single action like the 1911. When U start lightening that kind of trigger, I will get failures to fire. A gun smith can more than likely make the trigger feel a little smoother and maybe lighten it a tiny tiny bit. But a double action only gun is meant to have a long, heavy trigger to avoid accidental fire.
