Will this adaptor work on the adaptor threads for the P322?

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on November 17, 2022

No, this SIG SAUER Thread Protector uses M13.5x1 threads while the thread adapter for the P322 uses 1/2x28 threads. I would recommend the Strike Industries Barrel Cover Thread Protector, found by using the link below:

If your MPX utilizes M13x1 LH threads, this SIG SAUER Thread Protector will be compatible.
