This new kit contains the Firing Pin Plunger (1911) stainless steel, Plunger Lever 'N' (1911) and the 1911 Firing Pin-series 70, 80 (polished steel). These three items are quality parts not found in a package like this. If you have a series 80 1911, this is a kit you may need.  This lever elevates at a higher level  and is no longer in production. It will allow your firing pin to clear your slide plunger when installing after market triggers that have over travel set screws. 'N' stands for "National Match".
