I haven't shot my p08 in awhile but almost every time I do this pin tries to come and and the piece inside the toggle falls out. I was thinking it should be staked but that would damage the gun. Maybe a drop of super glue or something?

I'd like to shoot this more so I can try to figure out why my mecgar mags sometime work 100% and other times won't even strip the first round from the mag.

The easy way is to tap it out a bit, then put a bit of a bend into it, then tap back in. You could also blue loctite it as well.
