axis pin keeps falling out..
 

is there a reason it may slide out so easily? There is a very small hole on the breechblock right behind the head of the pin, is there something in there that is supposed to hold the pin in place?

If you are referring to the pin that goes through the toggle knobs, then there is supposed to be a small retaining pin that locks the axis pin into place.

At least on the P08 design. The Swiss 06/29 and the Mauser Parabellum don't have this pin construction.

If you are referring to the first or third pin, I've had Lugers on which one or both would fall out with no detectable ill effects other than the danger of losing the pin. I've never had the 2nd pin fall out as there is the tiny little pin to lock it in place.

If they get too loose they can cause feeding problems. If they are that loose you will have excess side play in the toggle when it's raised.

I don't know how to describe "excessive". Just compare to a few other Lugers.

I also am having this problem. How do I replace the retaining pin? I have managed to find some replacements.

If the mid axel retaining pin does not raise when hit with correct sized punch on the bottom, it may have to be drilled out. For those with missing or shorten one, you may want to consider the Mauser Parrabellum approach, that uses axels that are concave on the ends and easily flared out, to hold in place. I these in stock @$10 each including S&H and less for volume. TH

Thank you gor the information and advice.:burnout:
