pm7 trigger pin?

[echo34]

how do you get a trigger pin back into its original postion, so that it is flat against the grip frame, without damageing the frame? i can't get it to go back in all the way on my PM7

Once you've made sure the pin is in the right way round it's a job for one of these;

and a hammer, with a light touch to avoid hurting the anno around the pin hole.
