Today, I finally got the nerve to disassemble the frame of my 9mm commander carry. I was a bit intimated by the ambi thumb safety. With a piece of mylar film and a thin knife blade, it came apart easily. After removing the grip safety, hammer and hammer spring housing, much to my surprise, I found a reduced power sear spring. You know, the ones that have some of the metal removed from the sear and the return tines. However, I don't find the trigger to be that light. I put a reduced power spring in my piece of crap Springfield Armory 1911 and had to remove it because the trigger became overly light. I'm not an expert shooter.
