I have never seen nor heard of a 130-pound pit. A dog that size has a whole bunch of genes in it that are NOT American Staffordshire Terrier.
‘Pit bull’ includes some larger breeds, as this opening wikipedia paragraph details:
“The term pit bull is a generic term used to describe dogs with similar physical characteristics. Usually a “pit bull” is considered one of several breeds including the Staffordshire Bull Terrier, American Pit Bull Terrier, American Staffordshire Terrier, Bull Terrier, or any mix thereof. In some parts of the world, the American Bulldog and Dogo Argentino are also classified as a “Pit Bull-type” dog, despite major genetic differences. Any dog that is mixed with a “bully breed”[citation needed] may also be called a “pit bull” including those that are descended from the English Bulldog, French Bulldog, Boston Terrier and Cane Corso.[2] The pit bull is not a distinct breed which may make it difficult for experts to identify,[3][4][5] and while mixed breed dogs are often labelled a “pit bull” if they have certain physical characteristics such as a square shaped head or bulky body type,[2] visual identification of mixed breed dogs is not recommended by the scholarly community.[3]”
