I am putting in the m94 safeties on my px4 and I managed to pop out the firing pin block and somehow shear the block spring. I got a new spring, and can't manage to get it and the block back into the slide correctly. It will sit loosely, and when I depress it to replace the firing pin, the firing pin will slip about halfway in, then both it and the pin block are stuck.
I imagine I am probably overlooking something pretty simple here, but several YouTube videos have been no help.
Thanks!
