1) Take it apart.
2) Remove the toggle link pin and bolt/toggle link.
3) now your Parabellum is field stripped.
4) Insert bolt/toggle link. Observe that the bolt wont go in all the way. It hangs on the sear and holds back the firing pin.
5) Manipulate toggle link and insert pin.
6) Press the front part of the sear and the firing pin will pop forward + the toggle link will pop down in a sweeping motion that does'nt damage the firing pin ;-)
