Designed for use in compact sized XD-M Elite 10mm models, this magazine effectively transforms the grip from compact to full size. The package includes a magazine sleeve that aligns perfectly with the installed backstrap on the pistol, creating a seamless transition from compact to full size while providing extra capacity in a compact platform. For a proper fit, use magazine with sleeve #2 along with backstrap #2. This setup allows you to optimize your firearm for comfort, control and increased ammunition capacity in any shooting situation.
