Using many videos and threads,
I polished all internals to a chrome-like finish ( there are some machine marks, can't go too far with sanding and polishing).
Installed myself from CGW,
reduced block plunger spring,
18# hammer spring,
reduced firing pin spring,
Reduced power trigger return spring
Relieved some pressure on the trigger bar Spring
I now have a 9#10oz DA...2# 12oz SA like buttered butter : )
