Thanks John,

I was pretty certain that if I met the 16 inch barrel length that I would be OK.

I was not aware of the SBR request proccess. That is interesting.

Still a question in my mind is what happens with regard to the FFL database, i.e, the gun is sold to me as a pistol originally, then later I sell it and it is now a carbine..

With regard to the project, still in the research phase.

I am pretty confident I can handle the construction of the forestock, frame extension, accelerator, stock attachment, etc. The barrel is the hurdle.

Marstar in Canada sells a luger 16 in. barrel and forestock for about $200. However they do not list the caliber. I would like 9mm. I would also like it in stainless steel.

I would prefer not cutting a barrel blank. I have a metal lathe and I have contoured barrels previously, but I am not sure it is up to cutting the threads for the luger.

"Luger Tips" mentions that Springfield barrels fit the luger. Though I think the author is just refering to the caliber and not the threading.
