Greetings All:

I recently purchased a Mauser Broomhandle which was sold as rechambered for 9mm. The serial number is 671597 which dates the pistol from 1921-1930. My question is, how can you tell if the pistol was rechambered for 9mm Parabellum or 9mm Mauser? Is it as simple as trying to insert one of each of the rounds? I don't have a 9mm Mauser round but I do have a 9X19 Luger round and it seems to fit correctly in the chamber. I would like to shoot the pistol just to see how well it operates but I don't plan on using it frequently. In any event, I don't want to attempt to fire the wrong cartridge. Sorry for the elementary question...I don't know much about these and would just rather be safe than sorry.

Dale,

Only a few Broomhandles were originally chambered for 9mm Mauser Export and I seriously doubt any were ever REchambered for that caliber. Many Broomhandles were imported from China with shot out barrels and a lot of those were rebored and rechambered for 9X19.

I'm not sure how the diameter compares between the two cartridges but the 9mm Mauser Export is 9x25. If the pistol was chambered for 9X25 and the 9X19 will go in the chamber, then it will drop in the chamber far out of reach of the firing pin. There is a 99.99% chance your pistol is 9X19.

Regards,
Bill

Geladen is correct. Length of the 9mm Mauser case is .980"; length of the 9mm Luger (Parabelllum) case is .754". Since head and neck dimensions are within .003, the 9mm Luger will enter the 9mm Mauser chamber too far to be struck by the firing pin unless your firing pin protrusion is greater tlhan .225", which is not likely.

Thanks, Guys. The 9X19 Parabellum (Luger) round looks like it fits perfectly (bottom of the case is flush with the chamber when inserted) but I wasn't sure if this would happen with both the Luger and Mauser 9mm rounds. So, I guess if I tried to put a 9mm Mauser round in the chamber, it wouldn't go all the way in anyway since the case is longer and the neck of the round would stop inside the barrel. Is this correct?

I figured a 9mm Mauser Bolo would be very rare but I didn't want to find out I was wrong the first time I fired it.

You got it.

To be absolutely sure (99% of the time) you need to take it to a qualified gunsmith and have him make a chamber cast. Of course you can do this yourself but a professional's opinion is solid back up and he can confirm bore diameter and evaluate the overall condition for shooting.
