These wraparound rubber grips are a great choice for shooters looking for a sleek grip that is both attractive and functional for their Mark IV™ 22/45™. This grip is manufactured from a soft durable rubber and features a lightweight, synthetic Skeleton insert that makes up the rigid interior of the grip. The synthetic insert is chemically bonded to the exterior rubber grip insuring that the grip won't delaminate or come apart. The cobblestone (stippled) surface of this grip replaces traditional checkering and provides good grip control. The material is solvent and oil resistant and will not deteriorate or dissolve due to cleaning your firearm. Grip screws not included. Made in the USA by Hogue Grips.
