I've found with my PRO CDP II that I need to press the slide stop down first and then push it out. The "ear" on the stop will not clear the notch in the slide by a hair. When I press the thumb lever of the stop down that hair it pops right out. If it hangs up again watch for that.Picked up my Micro 9 SS yesterday after a long wait. After reading the owners manual I sat dos to breakdown the gun to clean it before shooting for the first time. However, I am unable to remove the slide stop pin! Anyone experience anything like this?
