I know Ruger DID NOT make a 6 1/2" barrel in 30 carbine.
That is a 6 1/2" barrel something. Has to be a 357?????
Look at the location of the rear of the front sight in relation to the ejector rod housing.
Look at these 7 1/2" barrels and sight location.

Seller has a 6.5" .41 Mag listed that has the grip medallion rotated to the same position. Different pics but I think it is the same gun. He likely grabbed the wrong box when taking pics for the .30 Carb. Specs in ad say 7.5".
