On the misfeeds, I used a dremel tool with a conical pad. Put some red jewelers rouge on it and polished the feed ramp till I modified it slightly. I was able to smooth the top of the barrel slightly. I was able to shorten the tip of the feed ramp slightly. These seemed to fix the misfeeds and stovepipes. Did the same for my DB380. It's now my carry gun. With these mods, I have put several hundred rounds through each without a misfeed. Never had a trigger reset problem though, like you had. See my youtube video.
