Thread pitches

[RyuNoKai]

Just wondering if the thread pitches on all the HK .45ACP's are standardized. I know the Mark is RH, and Tactical is LH. What about the Compact tactical, HK45 TB, HK45C TB?

All the .45 Tactical threaded barrels are threaded the same except for the RH threads used on the Mark 23. Same pitch and thread count on the it but in the opposite direction.

Thanks BB! Now to go find those barrels. . .
