Newbie, Thrown Into The Luger World By Accident

Doubs · 08-24-2022, 05:53 PM

Mrerick has identified the most likely cause of the problem; a stuck disconnector pin. The pin must depress and extend freely. If it is stuck in it's extended position, the Luger will not c0ck as the slide moves forward after firing.

When the trigger is pulled, the L-arm depresses the pin flexing the sear bar outward and releases the firing pin. During recoil, the L-arm is still against the receiver because the trigger is still depressed. The pin has moved rearward with the receiver and moved out from under the L-arm. As the receiver moves forward, the pin contacts the L-arm and is depressed. The sear bar remains straight and the sear engages the firing pin, cocking it.

IF the disconnector pin is stuck, it contacts the L-arm while moving forward after recoil and the sear bar is flexed outward preventing the sear from engaging the firing pin and the gun is not cocked. Once the trigger is released and the L-arm moves away from the receiver, it is then necessary to manually raise the toggles to c0ck the Luger again.

I once had a 1917 Artillery Luger with the identical problem. I soaked the sear bar in Kroil overnight and it freed the stuck disconnector pin. It then ran like a clock.
