The Agency Arms 118 Dual Port Smith & Wesson M&P9 1.0 Barrel Compensators do use 1/2x28 threads and would thread to your barrel. However, they were specifically designed to fit the M&P9 (3.6", 4", 4.25", and 5"), and match with the dimensions of the M&P slide at an optimal .695" of overall barrel protrusion. So it will fit your Canik, but it may not function as intended.
