FX Wildcat MK3 Compact

I think it is possible, on paper.
Mods including and not limited to , "HUMA slug probe, hammer weight and hammer spring" will be needed.
Shot cycle, shot count, accuracy and reliability will be a moving target to tame.
Would not qualify as my "go-to gun"
My (sold) .30 MK3 I was able to tune to 90fp w/ 44.75, with your additions along with a PP and Huma regulator that added a few cc more plenum with the 1" spacer I made.
Good on paper, no fun in real life.
Go for it and let us know what you learn.
