I have the commander with the bull barrel.First off which model did you buy? BUL who makes the pistols take a Government slide and cuts it down. The frame sits in between a government and a commander frame length. The commander uses the bushing less bull barrel to keep a bushing barrel set up from pounding itself to death. The only non mim part is the firing pin. I replaced everything else but non load bearing, ie grip safety , plunger tube , mag release, and trigger. The grips are a John Harrison design. The grip is not aggressive enough to tear your clothes but when you grip the grip the groves allow you to grip better but as soon as you release your grip a little you can manipulate the controls as needed without the grips sticking to your hand. It works well. Anymore more questions I will be happy to answer. Also if you buy parts for their commander the part will need to be government parts. I also had a Wilson combat 4" flat spring guide rod setup. Love it.
