1942 Luger Issue

mrerick · 07-27-2015, 02:37 PM

First, ensure that you're using brass cased ammunition.

Take a look at the back of the receiver between the ears where the toggle train rear piece hinges and it touches the rear surface when fully in recoil. Is it leaving any marks there?

The recoil spring on a late Mauser made Luger should have 19 to 21 coils.

Check all the toggle action to ensure it's clean and lubricated with light oil.

Check the inside surface of the chamber to ensure it's clean and shiny. Any pitting there would be a possible issue.

Ensure you are supporting the pistol properly when shooting. It does have a great deal of impact on proper cycling.

Double check the OAL of the ammunition. Try cycling a round in, and then remove the round intact without shooting it. Are there any marks where the rifling starts along side the bullet surface?

Magazine is not dragging. Ive cleaned the gun, bore brushed
The chamber and oiled the toggle, bolt area, slide rails.

On my luger if you pull the gun back 7/8" or so, the striker cocks and if I let go, the toggle will stay up slighlty (without a mag inserted).

My failures to go into battery duplicate this position.

The gun is head tightly when fired. The failure happen about 10% of the time.

I will count the spring coils when I get home from work

The oal cartrige should be fine, but Ill check when I get home. The ammo Im using fires fine in a hi-power and P-38

This is normal for the toggle to not return to battery if raised enough to c**k the striker and then released. If you are using quality ammo...i.e. WWB, PMC, S and B, etc. then that helps us a lot, although many lugers are ammo sensitive.

I am beginning to focus in on a tired mainspring. Have you, or anyone else ever changed it? springs do lose their strength over time.

If you are trying to shoot reloads in your Luger, stop that for right now, and use only good quality factory 115/124gr RN FMJ ammo. Use the factory ammo as a base/standard and then we can go from there.

Ive shot just factory ammo. Everything in the gun seems original. Ive already ordered the mainspring, extractor spring to replace.

This is my first P08 and Im just trying to get it to run 100%.

My next outting Ill try some winchester white box 115's. I shot 124's because I read thats the best weight for the P08 (ball)
