Designed to fit 1/2 x 28 threaded barrels, the Samson Pocket Comp for M&P9 Shield and M&P9 Shield M2.0 installs in minutes without the need for gunsmithing. The Samson design uses a threaded interface which protects the barrel threads unlike conventional compensators. The Samson Pocket Comp for M&P9 Shield blends with the aesthetic lines of the slide, creating the image of a slide extension. Machined from 7075 aircraft-grade billet, the Pocket Comp is Mil-Spec hard coat anodized for durability. The Pocket Comp efficiently reduces felt recoil and muzzle rise, allowing faster recovery between shots with iron-sight or red-dot equipped pistols. It functions with the factory recoil spring using a wide range of bullet weights and velocities (124gr or heavier recommended, may work with 115gr depending on manufacturer and/or environmental conditions). Pair a Pocket Comp with the Samson Compact Magwell for M&P9 Shield to turn your M&P Shield into a formidable shooter with an extreme level of control.
