If you have the screw out, the only thing that would hold the firing pin and spring in would be debri.
pulling it out with needle nose would not be a problem.
You could take the recoil rod, push the FP in, slip the rod of quickly and the pin could spring out.
tapping the slide while holding upright might shake it out.
you might also get the pin out and the spring stay stuck
cutting a qtip at an angle will push into spring to pull it out
there was recent post where I provide the drill bit sizes if you have a set of numbers
