This is my first revolver and my first Ruger, so I was not aware of its markings. Prior to purchase and researching, I was unfamiliar with the whole moonclip ring on the cylinder. Plus, with COVID rules BS, it was extra difficult to handle and inspect. The serial number specifically has it documented as an SP101-5783 9MM, so I don't blame the store (although they could have inspected it more closely). It was a mixup at Ruger. Bubba, probably, as was previously statedSo did a gun store or private seller misrepresent what they sold you? Not trying to be rude but if is stamped 357 Magnum on the barrel, what gave you the idea that it was intended to shoot 9mm?
Seriously, thanks everyone. This is a great community that I'm grateful to have stumbled across.
