Springfield Armory Magazine: XD(M)45: 45 Auto/ACP: 13rd Capacity w/Grip Sleeve #1 - XD45451

XD-M® Compact 13-Round Extended Magazine, with magazine sleeve 1, for use with backstrap size #1 - .45ACP

This magazine is intended for use in compact sized XD-M and  XD-M Elite .45ACP models, effectively converting the grip from compact to full size. The included magazine sleeve, as noted, aligns with the installed backstrap already on the pistol creating a seamless transition from compact to full size and allowing the user extra capacity in a compact platform.  To ensure proper fitment, magazine with sleeve #1 needs to be used with backstrap #1.  

Note: Requires removal of magwell for proper fitment on XD-M Elite Compact models.  Current production .45ACP XD-M Elite pistols ship from factory with Backstrap #1 installed.
