Send some pics.I think I'll have to take a look at that Magwell for my XDM OSP 4.5". Hopefully it doesn't print when worn under a cover garment.
Buy a pearce pinky extension bottom, they work excellent. I'm able to get my whole hand on the XD-m.45acp compact.I wonder if the larger magwell will work on the compact making the grip just long enough to accommodate a three finger grip.
