7,65mm Luger - Nambu T 14
 

I've been thinking about this combination for a few years, and got a little bored with wood working on the Erma boxes over the holidays-so.... I decided to add a take off 7,65mm Luger barrel to a spare T 14 receiver with poor bore.

The combination "works", I had it out for test firing this past week.:thumbup:

The original barrel was cut from the T 14 at the receiver chamber-barrel transition point. The receiver then bored and threaded to 18mm x 20 TPI of the luger barrel.

The barrel flange was "adjusted" to headspace the barrel to the T 14 bolt; the extractor cut then made and the barrel secured by crush fit with a little loctite added.

The original T 14 extractor and ejector work fine; the magazine lips needed to be tweaked in a little to hold the slightly smaller luger cartridge within the magazine.

I wondered initially about the "recoil" of the luger round, since it is a little hotter by fps; and the 8mm Nambu is often spoken of as "weak".

First ammo I tried was Fiocchi .30 luger, it would not lock the bolt open on the T 14/.30- same problem as I have had with some .30 lugers and this ammo.

Next tried Privi Partizan .30 luger, and it worked fine, cycled and held the bolt open as it should; which is similar to my experience with it in a .30 luger.:thumbup:

So it seems with this particular T 14 and its springs, the recoil of the 7,65mm luger cartridge is quite similar to the original 8mm Nambu.

I love seeing and hearing about these types of "conversions". So glad to hear that your Nambu now has a new outlook. I have been involved with caliber changes over the years, but none as extensive as yours.

So would this be a "Gerpanese" pistol?

Always knew them Germs and Japs were in cahoots. :D

No Bill,
it is all American now.:cool:

Afterthought. Too bad you didn't have/used a standard .30 barrel.
You would have a more harmonious outcome, me thinks. :p

Gives an a very interesting look and easier to come up with 30 luger than 8mm nambu (the stuff I have used by 'mr nambu' was disappointing to me. And my Midway boxes are too expensive to shoot !

the stuff I have used by 'mr nambu' was disappointing to me

Why disappointing?
dju

:eek:The only thing non-standard is the front sight! Normal 3 7/8" 1920 commercial bbl.

A thin 4 5/8'' bbl would look nice, but they are pretty scarce and I would likely not sacrifice one for a "fun" project.

Yes, easier to find and cheaper- easy to like!:thumbup:

I've had ok results with Mr. Nambu's 8mm- but others have not.
I think he had some problems at one time and changed his load, then had to change it back- or some such .

Don, don't forget... A pencil-tapered barrel and high, square sight block lie within the "meat" on a standard configuration bbl!

Yes,
but my barrel stretcher is broken!:eek:

Interesting conversion! :thumbup:

I think you are gonna catch hell from "Zorba, the Greek" for butchering a Nambu...!!!!

I doubt it, the Nambu now has a new lease on life and an "alter ego"!:p

Don- very interesting! When do you anticipate going into production? Bill

Around the 10th of never.:p

You could have said the 30th of February. :D At least it's a real month.:rolleyes:

To me, this conversion has changed it from a safe queen that may get shot occasionally, to a regular range gun that can be enjoyed and shown off at the range......a win-win in my way of thinking......but I am a shooter, not a collector.

Naw - at least he can now find ammo for it!

I've shot 50 rds of MrNambu ammo - had one slight hangfire of about 1/2 second, but otherwise was OK. He seems to have dropped off the face of the earth, I was going to have him reload my brass, but his email (as posted on his website) no longer works. I'll probably just have to get the stuff to reload them myself.
