I was told by a reputable source that a 9mm gun can shoot .380 just fine. I see that you have a SPF But you may not need to trade your 380 for 9.
This is bad information. Chambers are made for specific cartridges only. Only use the correct ammo for your gun.
My experiment/observation......... I tried placing a re-loaded 380 ACP cartridge into a barrel made for a 9mm cartridge. The 380 ACP cartridge will go into the chamber but, too deeply. That means that the firing pin will probably not hit the primer or will do so very lightly, probably causing misfires. And, although it might/could/maybe be held/supported by the extractor in the extractor groove when the firing pin strikes. I bet, I wouldn't be happy. Of course, a 9mm cartridge will chamber just right into a 9mm barrel. Not to mention, that 9mm ammo is usually cheaper and more effective on your "target." I also would say, "Use the correct cartridge for your firearms." Aloha, Mark
