I have several pistol barrels in 9mm that I wish to ream to .357 Sig. (For those unfamiliar, .357 Sig is basically a 9mm projectile seated in a necked-down 40SW case.) I already have several factory conversion barrels from gun manufacturers (Glock, Springfield Armory) as barrel swaps into their production firearms, so I know this is do-able.
The question is - how do I get this done for pistols outside of Glock and Springfield (i.e. for CZ, Tanfoglio, etc. pistols)? I am an end-user, not a gunsmith or machinist.
From the research I have done, it appears there are two ways to accomplish this task: with a mill, or with a lathe.
For the 7-8 shorter barrels I want done (i.e. 4-5 inches) I presume a mill would work fine. Additionally, I am looking to ream an 8.5" or 10" AR pistol barrel, which I presume could practically be done only on a lathe. Am I right in these presumptions?
I have acquired an interchangable pilot reamer for the task from PT&G here: PTG Chamber Reamer: .357 SIG (SAAMI). Are there any issues with this choice?
Now the real question - how do I find someone to perform this work? It seems that reaming barrels is a very specialized business, and not many people are willing to do things they haven't done before. So, how do I find someone competent with confidence to perform this work?
Thank you.
