I have a 96/92 Combo set. The frame, 9mm barrel/slide, and .40 barrel/slide are all specially marked "Combo."
This set is a quality product, and the 9mm mag that came with mine is even a hi-cap. Also included is a special, larger case to accommodate the extra barrel/slide and magazine. In sum, I'm glad to have it.
