Gunsmithing Threading a Pistol Barrel?

[dddoo7]

I am looking at purchasing an FN five seven. I want to use it with a suppressor. Will I need to buy a new barrel in order to have it threaded, or is the factory barrel long enough?

If I need a new barrel, where would I go about finding one? I don't see them at midway or brownells (which usually have almost everything).

For what its worth it will be used with a thunderbeast 22L-1 threaded 1/2-28.

Buddy did the same thing, Jarvis makes a threaded drop in barrel

That's great. I knew I had seen threaded Five Sevens, but could not see where they were getting the barrels. Thanks.

I had to order a thread adapter for mine to change it from a M10x1 thread to the 1/2-28. I think the adapter was about $45.

If I recall his 5.7 had the metric threads, but they matched his dedicated 5.7 can

Yeah. I read somewhere that metric threads are necessary in order for the pistol to be disassembled. I guess the 1/2 - 28 are too big. I probably won't have a dedicated can, so I guess I will get an adapter. I'm not excited about the adapter, but the only other option is another $500 can and $200 tax stamp.
