The STI Steel Master is a purpose-built Steel Challenge competition pistol. Optimized for the fast, close-range target engagement of Steel Challenge, it features a shorter grip for faster presentation, a shortened slide for reduced reciprocating mass, and a bull barrel with compensator tuned for lightweight 9mm target loads. The Steel Master was one of the first factory pistols designed specifically for Steel Challenge rather than IPSC/USPSA.
