Hi, I was hoping someone knew the answer to this or where to find the info.. On a Coast Airbrush live feed on Facebook they were talking about putting the taller triggers from a Kustom (which is a two piece trigger like Eclipse) on other brushes that have single piece triggers. They said that to do the mod, you remove the valve pin? I was under the impression they meant remove the pin from say, a HP-CH under the trigger, and then an Eclipse or Kustom two piece trigger would go in the hole? What about the o-ring? Anybody know about this?
