Mission First Tactical’s Pro Series IWB Holster is an Inside the Waistband (IWB) holster designed for both right- and left-hand use. The ,In-line Magnetic Retention System, (ILMRS) provides a maximum pull of 11 pounds, with a strong Neodymium magnet that secures a fully loaded pistol in the holster without any locking devices. Retention does not depend on the (WML) Weapon Mounted Light. The ,Integrated Barrel Stabilizer Insert, (IBSI) is engineered to keep the pistol slide aligned with the upper part of the holster body, preventing binding when drawing the handgun from awkward positions. Built-in Vertical Wedge is a revolutionary design that brings the top of the pistol closer to the body for ultra concealment, while a wedge against the body helps reduce holster slump or sag.
