Just wondering if someone in the know would tell me whether the Mk23 and the CT use the same threads on the barrel or if the CT uses the same threading as the regular Tactical which is different than the 23.......Thanks..

I'm no H&K guru, but I'd be shocked if they were different. (tagging for answer from someone who has a clue.)

I'm not positive, but I believe they are. I do know for sure that the Mark 23 and full size tac are different.
The full size tac has 16X1 left handed threads
The Mark23 has 16X1 right handed threads.

ya......i'm debating because if the threads are the same I may add a 23 to go along with my CT, otherwise I'll probably pass........

The CT and the full size Tac have the same thread pitch & direction.

MK23 has right hand threads.

USP Tac has left hand threads.
