9mm Nagant (or 9.4mm Nagant?)


#1

The Belgian military issued a 9mm Nagant revolver called the model 1878 and then an improved one called the model 1878-86. The cartridge for the Belgian revolver is often called 9.4 mm, which reminds me of the Dutch 9.4 service revolver but the two cartridges are not interchangeable. The Dutch revolver has a larger bore diameter. The Belgian Nagant bore size is smaller. Dutch 9.4 military cartridges will not chamber in the Belgian M.1878-86.

Does anyone have case and bullet data for the Belgian service revolver cartridge? Size, weight and length of the bullet would be interesting. There is rather limited information about this round on-line.

Thanks,
Greg

Greg,

Here is some basic information from Handbuch der Pistolen und Revolver Patronen, Vol. 1, Erlmeier & Brandt, 1967, page 136:

Technical Data-

Bullet dia. 9.25 – 9.30mm (.364 - .374”). Round nose lead bullet with paper patch.

Case diameters, Neck: 9.90 – 10.20mm (.389 - .401”), Head: 10.75 – 10.90mm (.423 - .429”), Rim: 12.00 – 12.35mm (.472 - .486”)

Berdan primer

Cartridge length 33.30 – 34.50mm (1.311 – 1.358”)

Cartridge weight 11.95 – 12.30gm (184.41 - 189.81 grains)

Production ceased around 1914.

Another source indicates production occurred in Belgium and Germany.

Hope this helps.

Brian

Thank you Brian. Is the bullet weight given in any source?

According to the Erlmeier & Brandt book the bullet weight is 11.95-12.3 g. If you want a detailed factory drawing of the 9 mm Nagant cartridge, I suggest the ECRA CALIBER DATA VIEWER. Here you can see drawing no.10154, dated January 1919 from S.F.M. in France. The paper patched bullet here is 12-12.3 g, length 20.0 mm, diameter 9.05-9.15 mm without patch and 9.35-9.45 mm with paper patch. There is also another drawing from S.F.M., 10080 dated Dec.1900, which shows a slightly different case, but fewer details.

Many thanks Vidar. I will try to check out the ECRA data. Maybe I’ll be fortunate enough to locate an example of this round some day.

This cartridge is also known as the Galland and the Erlmeier Vol 1 page 174 that I have list that cartridge as such
I nearly went crazy I have the thing but had it listed under both Nagant and Galland however the one I have is
listed as Galland in Herschel C Logens book with the same stamp as given in the book. C R B 99 and 2 stars.

Sherryl, Many thanks for the data. I would never have thought to look for this round under the name “Galland” It would appear that the Nagant M1878 was chambered for a preexisting cartridge.
