The HS Produkt H11 magazine sleeve fills the gap between the pistol grip and an extended 15-round magazine. Once installed, it creates a smoother continuation of the grip profile and provides a more consistent support surface for the hand. It is compatible with the HS Produkt H11 and corresponding Springfield Armory Hellcat platform.
The sleeve is intended for the extended 15-round magazine used with the HS Produkt H11 pistol and the corresponding Springfield Armory Hellcat platform. It fills the exposed space beneath the pistol’s shorter grip.
When an extended magazine is inserted, part of its body may remain exposed between the bottom of the grip and the magazine base plate. The sleeve covers this section and creates a smoother transition from the grip to the magazine.
By extending the external profile of the grip, the sleeve provides a more continuous gripping surface. This prevents the hand from resting directly against the exposed portion of the magazine body.
The sleeve is neither a magazine extension nor a base plate and does not change the magazine’s capacity. Its sole purpose is to improve the external grip profile when a compatible 15-round magazine is used.
