View Full Version : 9mm Largo Conversion

February 22, 2002, 11:45 AM
Nonte's book had sugested a bushing to fill the chamber for heads spacing to convert 9mm largo guns to 9mm Luger. Does anyone make these bushings, or no where I can get one.
I want to conver a Spanish destroyer carbine as the ammo is getting hard to get at time around here and it would just make it hander.

Thank you:cool: :cool:

Friend of mine cut an appropriate sized ring from a case mouth, ceaned and degreased the chamber and ring.......placed ring over a ball 9X19 round, put a dab of locktite on the ring, chambered round. Has been workin fine for quite a while now.

I did a couple, but made steel rings, which is not a hard job on a lathe. Worked fine.

To do the job right, you have to run a 9mm chambering reamer in as the Largo is a straight case and 9mm is tapered. The 9mm may wedge in the chamber, but will not headspace right, otherwise.

That's interesting Jim, I will pass it on.

Thanks Guys...I was thinking the same hing about trim a case or using even a steel wolf ammo case to make the bushing. ..I'll look up Nonte'sarticle as he talks about a home made reamer also for the job...
Again..Thank you.:) :)

My friend used steel Wolf case for ring material. Forgot that point, sorry.
