Anyone willing to help me out with a technical/assembly type question on my SIG P220? Would greatly appreciate it. I removed the grips today and would not of imagined a small metal part fell out. I done nothing but field strip and remove the grips. Might have come from the left side ambi safety selector. I have looked all over the web and can't find a full strip of the P220. I have no problem taking this completely apart. However, I need to know what the heck fell out and from where.
