I recently picked up a compact 10mm elite and am enjoying it, but I have to special order all range ammo due to lack of 10mm available locally. I have plenty of 40 and it is readily available on the shelves. I would be interested in shooting 40 if possible. Does anyone know if dropping in an aftermarket 40 xdm compact barrel would work? I am not interested in shooting 40 cal in my 10mm barrel due to the difference in head spacing, so that is not an option for me. I appreciate the insight.
