Firing Pin Gauge

Could the round notch be to check the contour of the firing pin tip?

Just a thought.

I am not really in the know for all of this, but seems to make logical sense, just a bit of simple comprehensional skills. Doubs picked right up on the thought presented; but of course, he has been around a while and is quite knowledgeable.

We read a lot here about firing pin shape. Round is round sorta speak; kinda like right is right........anything less could be trouble sometime.

I learned about making a perfectly round cut at the end of a rectangular cut, sights for African rifle with blades. Getting the round to be perfect for the wedge, ie no line show, was a trip for me. Did not happen the first time.

I would suspect that the round in the tool could be done with a wheel or small ball mill, either one custom ground probably; but for a supplied machine shop, no big deal.........precision grinder.

I remember these German tools, so marked, and with the same shape features come out of digs in later times, then sold on the markets abroad. A friend in Berlin was generous enough to share a few with me...............never used them, depth mic is my friend; but for the collector, a tool like this seems appropriate...........of course collectors like originality. That asking price seems a bit out of line, but I have not been in the Luger deal for a good while.

The rounded notch is Way bigger than a firing pin tip.

Never having held one, the picture is all I have to go by.

As I said, it was just a thought but I'm certain of one thing; the rounded notch has a purpose. We just don't know what that is.

The notch may just be for holding in position in a jig or other fixture.
Also notice that the notch is significantly different in size in each of the two tools shown.
Either one is not of a size that "fits" any part of a luger.
