Questions & Answers
Is this item compatible with the B&T GHM9?

The GMH9 has 1/2x28 threads so this would NOT be compatible as it as 1/2x36 threads.

The FM Products PCC Forward Blast Diffuser is 0.97" wide and 1.5" in length. It will support 9mm and 1/2x36 threads.

This thing is so freaking sweet! Basically looks like a tiny suppressor! I bought it for my Foxtrot Mike FM9 which I thought came with it but didn’t. No problem super easy install just twist off and twist this baby on! Makes the gun look so much bett...
