Muzzle Threading:

Muzzle is threaded 1/2x36 threads per inch on 9mm barrels (at RRA/Colt factory) as opposed to the 1/2x28 tpi use on 5.56

Olympic will thread 9mm only in 5/8x24 by default or 1/2x28 when asked. Other pistol caliber barrels are threaded 5/8x24. (Per Mark Budam at Triple Break Products)

Barrel Sizes:

9mm postban RRA barrels measure .718" diameter at muzzle, .750" at front sight, and .675" under handguard.
