I have not seen a 320 in 380acp, but I have a Sig 380acp barrel marked as P250/ P320. I am wondering why? Can this 380 barrel, (talking sc), be used in a 320sc? It is smaller, but not shorter, than the 9MM barrel. Are there plans in the works for a dedicated 320 in 380acp? I am new here, and new to the 320, which I just bought yesterday. Thanks!
