Can someone let me know if this is real or reproduction?

Id say just look up what a real close combat clasp in silver looks like, and look for one that have the same manufacturing marks as that one beacause some may be manufacterd by a different company in diffrent year. Just do some reasearch and youll figure it out, plus theres quite a few markings to go off of.

The one thing that gives me pause is that the black magnetic steel square on the reverse seems to be glued in rather than having some kind of "lugs".
