trouble with a P-08 luger.

Roguetek · November 26, 2007, 07:44 PM

a friend of mine brought a luger to me for service.

headstamped 1917 WWI/WWII bringback, artillery model, serial 7XXX all matching.

It wont go into battery.

User claims failure was sudden, not gradual ( "it fetched up right in the middle of shooting, no warning at all! " says the owner. )

Using this link as a reference.

Inspection reveals that the bolt assembly will only go fully into battery with the firing pin in the foreward uncompressed position ( you have to pull the trigger to get it to drop into battery. )

With the firing pin charged, the breech block face stops about 0.8 mm from matching up to the chamber.

The Main spring is not factory, and appears to be 'made to fit'. It does -not- fit correctly, allowing the toggle to 'slop' almost 10mm up and down without spring tension.

While I know that a new mainspring will be required, I'm uncertain as to the rest of it. reference materiel suggests a new firing pin assembly, but I cannot find anything wrong with the old one.

Removal of the firing pin assembly (parts # 22,23,24 ) -does- allow it to slide into battery.

it would appear that the firing pin ( part #22 ) is not sliding far enough back
in the breech block ( part #17 ) when the firing pin is in the 'charged' position. the entire breechblock assembly winds up hanging up on the trigger bar ( part #7 )

I'm sure some of the guys here are Luger experts, but up there everyone is!

Have you removed the firing pin spring guide and checked it, as well as the firing pin and its spring?

Firing pin, firing pin spring, and firing pin spring guide rod all check out.

installation of a new mainspring, and shaving .2mm off of the sear catch on the side of the firing pin resolved the problem.

works like a charm now.
