Here ya go, this is the 6-32 screw and a short section of threaded aluminum sleeve, I turned the head down in the drill press with a file, left it "in the white"
, it weighs 23.3grains, it's the same length as a factory extension. There's lots of clearance at the barrel release and I left the spur factory length so you can see how much hammer spur you can remove for more clearance, it could be mounted lower on the hammer too, I think the 8-32 version should be mounted lower where the spur is thicker, there's not a lot of meat on both sides of the spur at this position.
