I have a mkIII competition, a buckmark hunter and an AA .22 conversion for glocks. The mkIII was about a hundred more and needed a volquartsen trigger to put it on an even playing field with the buckmark. I find no difference now, but my wife prefers the buckmark. It will eat almost any ammo but gets a bit finicky if it starts to get dirty. Keep it clean and it never stops.
Don’t bother asking about the AA conversion...
