Sorry for the multiple posts, but file size limit made me upload one pic at a time.
This is a lone wolf 9mm compensator on long slide CZ. Frame is SP01 shadow, slide is TS, barrel is from CZC, threaded TS barrel.
The comp fits and functions fine. I only got it for looks and plinking. I shoot factory ammo with 13# recoil spring, and it functions and cycles flawlessly. Not sure if it actually reduces any felt recoil or muzzle climb, as my other similar build (without threaded barrel) feels nearly the same. The slide travel during recoil does feel a bit sluggish, perhaps needs major ammo or an even lighter recoil spring?
