If you made an effort to learn this stuff instead of trying to make it up on your own, you'd see that 9/16-24 threads are an industry standard size for hunting profile barrels, as well as 40 cal pistol barrels. As I already said earlier in this thread. And it's right there in that TB thread spec a few posts above, and a couple other manufacturers publish specs for them as well. A shoulder of about .660" is generally recommended. But I'm sure you'll need responses from a couple other people before you listen...
