There is a kit for the xd/xdm for 460. Everything ive read the xdm makes a better host than the 1911.
I just wouldnt use any host gun as a carry piece with or without the kit installed. The battering a gun frame and parts take from that monster round is huge. Would be a bad time for stress failure when you need it most.
