The XD elite OSP, fde one, looks like it has a longer mag flare on the end compared to the 3.8 full size Elite flare, which fits the 19 without the flare and 20 with, thanks
Yes, the 19-20 round magazines will fit the full size XDM Elite with the mag well. And the 3.8 compact with mag well. However, on the compact you can remove the mag well and use the mag sleeve on the 19 round mag to make the grip more like the full size. There is photo on our website.

That's odd, the 19rd mags I've got for my XDm Elite insert but won't lock up unless I remove the magwell. Heck, they won't even lock up with the smaller magwell I ordered from y'all(that came without the pin that goes up into the grip and is held in by the roll pin).
