When I took mine out, I used a punch. Something like one you would use for setting finishing nails. I had to hit it pretty hard several times. It did deform the plastic pin that was in there from the factory, but the replacement went in without any problems. I have had no issue with it since it was put on. I took mine out by laying the pistol on the its side with the ejection port facing up. Then just beat it out. Hope this helps. Maybe someone will have some better tips for doing this. Good luck with it.
