Hi Marquish and welcome. Pistol or magazine? the XD and Mod 2 magazines are interchangeable: xdgunparts.com/category/Magazines_XD9.html

Hi Marquish, there is a used one here >>> guns.com/firearms/handguns/semi-auto/springfield-armory-xd-mod-2-sub-compact-9mm-luger-(9x19-para)-semi-automatic-13-rounds-3-5-barrel-used?p=1095970
Also, I would check on large gun sites like gunbr0ker and Guns International as discontinued and hard to find firearms show up for sale by private individuals and small shops.
Stay safe & have a great day!

I’m look for the Mod 2 Subcompact gun - where can I find it?
