Congrats on finding a 320. Don't see many of them around.
IIRC the 320 uses the same magazines as the Kimber of Oregon model 82's. G Warne based the original Kimber rifles on the 310/320 action. The mags for the New York Kimbers will NOT work.

I may have an extra mag laying around here some where. If you need it let me know.
