The Faxon EXOS-524 compensator (brand part no. FF-P-A-COMP-SS-MP-01) is a 9mm pistol compensator sized for the Smith & Wesson M&P Shield 1.0, Shield 2.0 and Shield Plus. Faxon Firearms machines it from 6061 aluminum with one expansion chamber and three ports angled at 45 degrees. In its Ransom-rest testing on a Shield, Faxon measured a 29 percent drop in muzzle rise. At 0.9 inch wide and under an ounce, it keeps a carry pistol slim, and it sits flush on a Faxon threaded barrel. It is a good fit for shooters who want flatter shots from a concealed-carry size gun.

Frequently Asked Questions

Which M&P Shield models does this compensator fit? Faxon lists the Shield 1.0, the Shield 2.0 and the Shield Plus. They share the dimensions the compensator is cut around.

How is it kept from loosening? Thread locker goes on the muzzle threads and two 6-32 set screws index the compensator so it cannot rotate or back off. A 1/16-inch hex wrench is included.

Does it change how the pistol carries? It adds 1.125 inches ahead of the slide on a Faxon barrel and weighs about 0.8 ounce, so it adds length but very little weight.
