Luger Slam Fire?
5/11/2006 11:45:29 PM
This may not exactly describe a slam fire, but I was wondering if anyone else has had a Luger do this to them.
My toggle was locked open on an empty magazine. I put a new magazine in and then pulled back to lower the toggle. The gun fired when the toggle closed.
That sure got my attention.
Next time, I put the safety on before releasing the toggle. No slam fire this time.
Any clue why it did that?

Sounds like some part is dangerously worn.
Maybe the sear or some trigger part? So the "slam" of the lock closing may cause the sear to release accidentally. I'd take it to a gunsmith before shooting it more, you might get accidental full auto next or some such "fun" incidence...

First thing to try is bending the sear spring. This is the flat spring on the left side just above the grip panel. It controls the tension of the sear, if that does not cure it you need to check the angle on the sear and firing pin. These surfaces should be sharp and not rounded at all. The easy way to check is to drop the toggle on an empty chamber and see if there is trigger pressure. I have never had a sear failure, but I bet it would be invigorating to go full auto!

Have you field stripped the bolt before? I have reassembled my Luger with the firing pin assbackwards & it protruded from the breechface, enough to strike the primer had I not noticed it.
IMO, *I* wouldn't be bending any parts until someone else looked at the gun who knows what they're looking at.

I will check the firing pin first.

I am really curious how you managed to get your firing pin in backwards? If you truly installed it backwards the main part of the pin would be protruding under the front toggle link. The part I suggested he "bend" is the sear spring. This is the flat spring that holds tension on the sear bar. Giving this part a little bend will increase the pressure on the sear and not let it bounce. If he were more knowledgeable he would tweak the sear itself. This is done by bending the sear to increase or decrease the sear engagement. This is the way that the factory did it, but can cause problems if done incorrectly.

I guess I applied myself.
ETA: I wrote in error. I cleaned both Luger's last night & there's no way I could've installed the firing pin assbackwards.
However, for whatever reason, the pin was extruding from the breechface the last time I reassembled it.

What P08 said sounds right and is technically sound, but I would like to add that there could be a possibility of fouling or oxidation clumped up in there somewhere contributing to the sear not fully returning (possibly in the space betwean the receiver and the sear spring tab).
This is normal. The only 2 things that hold the firing pin back are the sear and the out of battery safety. If the striker assembly is out by itself or attached to the toggle assembly with the toggle assembly laying flat, it will stick out as far as it can go.
