No. You are not missing anything. Gibson does not make SG specific pickups.
I ran 57 Classic and Classic + in my 2018 SG Standard. They sounded better in there than in the 2013 Les Paul Signature T they came in. They really did come pretty close to an Angus type tone.
Who is aware that Gibson used two different string spacing at the nut and one Les Paul model in particular with a 14° headstock angle???
