XDM 10 was discontinued for a year and brought back. So the new model would be Gen 2 or Elite if that's easier for you. The Elite FDE looks basically the same minus the threaded barrel and the frame.
Will an XDM 10 OSP Gen 1 slide work on an XDM Gen 2 frame? I like my threaded barrel and raised sights and my slides engraved but I like the new frame look.
