So much better - Volquartsen Firearms MK IV Pistol Competition Kit

Much Smoother, and the trigger weight I was looking for. Just dry fired so far, but dramatic improvement.
Instructions aren't perfect (video does in a different order, and both skip a step or two), but well worth the price and effort.
I haven't had any of the ejection or other issues this is supposed to correct, so can't comment on those.
