Springfield Armory XDS5901 XD-S 9mm Luger 3.30" Black Polymer Backstrap Magazine Sleeve - #1 Backstrap

The Springfield Armory XDS5901 is the factory magazine X-Tension sleeve engineered specifically for the XD-S in 9mm Luger configured with the #1 backstrap and the 3.30" barrel.

Molded as a single one-piece design from durable black polymer, the sleeve slides down over the top of an extended XD-S magazine and fills the gap between the magazine base plate and the bottom of the pistol grip frame. The result is a clean, factory-matched grip profile that gives shooters a solid, full-hand feel when running higher-capacity XD-S magazines, while keeping the lines of the slide and frame uninterrupted.

This is a genuine Springfield Armory factory accessory, finished in black to blend with the XD-S frame, and is the correct sleeve for 9mm Luger XD-S pistols equipped with the #1 backstrap and 3.30" barrel. It is intended to bridge the base plate to the grip frame and is not a magazine or backstrap on its own.
