PX4 Trigger Group

I've watched videos on removing the group and done it. I have one which the top trigger group retaining pin isn't backing out far enough to grasp with fingernails. Any suggestions on how to get this to pop out? Applying a light-moderate amount of force with a flat head screwdriver isn't moving it any further.

Edit: Nevermind. I figured it out. Just pressed it back in place and gave it a fresh push out and problem solved.

See if you can move the spring with a screwdriver that holds it via a groove. I am thinking it started to pop back in that groove.
