I own a New Vaquero polished SS in 45 Colt, it is my 1st, although I have owned several New Model Blackhawks. I have tried to do an action job,( hammer, trigger, springs) and noticed that I cannot remove the trigger pin, it appears to be peened to prevent removal. Is this Ruger's new thing to prevent changing part's. I've never run across this on any other Blackhawk's that I worked on. Please comment and Thank You.
