P08 Luger Trigger Bar Plunger

The trigger bar plunger is an integral part of the P08 Luger's side plate assembly, where it applies constant spring pressure to the trigger bar. This controlled pressure keeps the trigger bar correctly aligned with the sear throughout the pistol's operating cycle and contributes to the consistent movement of the toggle-lock firing mechanism.

Manufactured from carbon steel, this replacement trigger bar plunger is produced to original dimensions for use in P08 Luger pistols built to military specifications. Its smooth bearing surfaces allow the plunger to move freely within its bore while maintaining uniform spring pressure on the trigger bar. Proper dimensional accuracy is important to ensure correct engagement of the trigger components without introducing unnecessary friction or excessive clearance.

During installation, the plunger should be assembled together with the trigger bar plunger spring and secured by the trigger bar plunger retaining pin. While the side plate is removed, it is advisable to inspect the plunger bore for fouling, corrosion or burrs that could restrict movement. A lightly lubricated plunger operating in a clean housing helps maintain the crisp and predictable trigger characteristics for which the P08 Luger is well known.

Suitable for maintenance, repair and restoration of P08 Luger pistols.
