M&P 9mm 4 Port Comp, Black


"NEW" CARVER Custom M&P 4 Port Comp (9MM Major) These comps were designed to fit the countour of the slide and to appear an extension of the slide. The compensators are made out of tough 6061-T6 aircraft aluminum and have Type 2 anodizing in two colors: Black and Silver.

Large expansion chamber leading into retaining ports. Porting on the sides allows more air to rush into the compensator pushing more exhaust up and allowing more control of the muzzle. Weight 1.3 oz. Guiderod channel under compensator.

Controls muzzle flip and recoil up to 45% dependent upon type of ammunition used. The higher power factors will deliver more efficiency. Stylish and effective!!


The comps are threaded for 1/2 x 28 tpi barrels. Though they will fit an M&P threaded barrel that's intended for a suppressor, Carver recommends the use of a shorter barrel that will allow the compensator to snug up to the end of the slide. KKM and Storm Lake make "Carver Cut" threaded barrels that reduce/eliminate the gap. Customers have to request the Carver Cut when ordering barrels directly from KKM or Storm Lake.

Carver Custom recommends an 11-12 lb recoil spring for 9mm up to 135 PF. Major loads will require heavier springs. Installation instructions are included. Black.
