First Luger- Identifying proof marks.

Ron Wood · 12-20-2011, 11:26 PM

The "KK/10" is a Portuguese marking and it is a replacement barrel. I have not seen a WWI Luger with a Portuguese barrel or possibly rebarrled by the Portuguese so this is a new one on me.

Dry firing is not a good idea. The firing pin slams into the interior of the breechblock and will crystallize over time and the tip will break. If you must dry fire it, use a snap cap...very inexpensive and will save your firing pin even if it is mismatched.

Yes, it is possible to fire a loaded Luger barrel/receiver group. Highly dangerous and not recommended. There are actual cases on record where individuals have been accidentally shot with a loaded Luger upper.
