I had a bitch of a time with mine too (was scared I would crack off the receiver's trigger mount)... I finally ended up using a small hex key that was the same diameter as the hole. Smack the hex key with a hammer firmly, and the pin should give - once it moves a little, it comes out easy with pliers on the other end or more smackin'... I know how you feel though - it's frustrating!
