Firing pin spring.

If you need to replace it, you will need a step by step guide.
PM me if you can't find it by search.

I have the same pistol, and just replaced both last week, after receiving from Wolff. Here's what I watched on youtube, and job was a piece of cake. BE CAUTIOUS... those tiny little springs in the safety lever can get lost rather easily! Good luck!
