p365 xmacro adapter plate - 15 round magazine
thingiverse
It turns out you can use p365 x/xl 15 round mags in the xmacro. BUT.. you need to modify the 12 round plate and have a gap or take a hacksaw to the 15 round plate and hope you don't have a gap. This remix should take care of it. I printed as shown for layer line strength. I used a brim and blocked supports for the red areas in the slicer picture. If you have supports there, they can be mighty difficult to remove even with larger than normal separation distance. I used PETG 50% with 4 walls 4 layers top/bottom. Clean up the supports and brim and you should be good to go. Might need to widen slightly the retaining hole.
