 the Rock Island Armory 9 millimeter revolver called the AL 9.0. Will this fire the smaller 380 ACP. The 9 millimeter round fits in nice and tight and the 380 it's just very loose. You can pull it out 380 ACP Federal 95 grade target loads. Alright that worked kind of comfortable. Miss that target. The Rock Island AL 9.0 was able to shoot 380 ACP.
