OT - Steyr-Hahn ammo

Dwight Gruber · 10-13-2002, 03:56 PM

Karl,

The Steyer-Hahn is chambered for the 9x23mm Bergmann-Bayard round. It is known by several different names, the Spaniards call it 9mm Largo, so your gun show information is on the money. You might also see it as 9mm Bayard or 9mm Bayard Long.

The bad news is, it is devilishly hard ammunition to find. The last commercial source I know for it was CCI Blazer, it is not currently in their catalog. I have found it by haunting gun shows and miscellaneous tables in gun shops (I shoot an Astra 400, when I can find the ammo). I have found both Spanish commercial ammo from the 50s (noncorrosive), and Spanish military rounds from the 40s. Be careful with the military stuff, it is probably corrosive and requires gun cleaning immediately after shooting.

There are a couple of ammunition dealers who specialize in hard-to-find items, I don't know them specifically, but others on the forum can probably point you to them or you can search them out online.

As a last comment, check for a "P-08" stamping on the back-left part of the slide. Ezell (P. 364) notes that the Germans rebarrelled some of these in 9mm Luger around 1938 and so marked them.

Anyway, good luck with it, and good shooting.

--Dwight
