Although the meathod of removing pins on a Glock are push. I feel that a pin that is not centered can be gently tapped into place. Just the same, some locking block pins can be very tight. The only alternative seems to be tapping the locking block pin lightly to center. Releasing most trigger pins is not that hard. Just wiggle the slide stop lever for and aft while you push the pin. However, I still feel that tapping the locking block pin (in the case of an extremely tight pin) is the thing to do.
