Stubborn trigger pin Mossberg 500

[Justincase]

Can anyone give a recommendation on how to get the trigger pin out of this old 500 trigger assembly? All the other pins came out with no issues. This one won't budge. I've had it soaking in PB blaster for over a day. Drift and small hammer hasn't done it. I don't wanna really wack it, cuz the assembly is that phenolic plastic and this gun is likely 55 or so years old. Plus there's not much material on the top of the assembly where the pin is. Am I missing something that may be holding it in place?

Try putting it in the freezer for a while, the steel pin will contract hopefully more than the plastic. Notice I said hopefully? I'm just guessing.

Maybe this will help?

Thanks for that. I've done that in the past with wheel bearings and didn't even think about doing that.

That's The video I was using to take the whole thing apart. He was able to push the pin out with almost no effort lol. That's what's got me scratching my head. There's obviously corrosion, but I'm very surprised at it's resistance to coming out.

Is the pin that's giving you trouble the one that actually holds trigger in? Not sure if order matters but guy in video takes that one out first.

Looks like it should just come out. Do you have a bench block to support underside while tapping it out with drift punch and light hammer? Alternatively a piece of scrap wood with small hole drilled in it. I think it should come out with a little persuasion. Also looks like the pin (holding trigger in) is brass wouldn't expect a whole lot of corrosion on it within plastic assembly. Good luck.
