I think Taurus has said that "OSS" stands for "Oh-Seven Submission" (or is it Oh-Six?), as in the pistol they submitted that year for the military contract trials.
There are a number of online sites which contain reviews of Taurus brand pistols. The web domains "PistolGuru" and "GunsAndAmmo," for example, contain these reviews.

Some well-known brands that produce .410 pistols include Taurus, which offers the Judge series, and Smith & Wesson with the Governor. Another notable brand is Bond Arms, known for their derringer-style .410 pistols. Additionally, the Taurus Circuit Judge is a unique option that combines features of a rifle and pistol for .410 ammunition.
In IT terms, OSS can refer to 'Open-Source Software', which is software that is meant to be modified by users however they like. OSS can also refer to 'Operations Support Systems', which is the term for a computer system used by a telecommunications company.
