The JS 9mm () is a commercial export version of the QCW-05 (with the exception of different chambering.) It is a suppressed submachine gun developed by the Jianshe Industries (Group) Corporation of Chongqing. The JS 9mm is capable of using any 919mm round, including the popular 919mm Parabellum round but has specifically been chambered for the indigenous, armour-piercing 919mm DAP92-9 round.

Based on the paragraph above can we conclude that "The JS 9 can use a Parabellum round, but is not chambered the same as another version of it."?
Yes
