Trubor GrandMaster

For those competitors who demand the ultimate race pistol, STI International delivers with the STI Grandmaster. Incorporating unique features with patented 2011 technology and Trubor compensated barrel, the STI Grandmaster is a race ready factory pistol with custom pistol distinctiveness.

Originally only offered from the STI custom shop, the Grandmaster is now a available as a standard model. Built on the patented modular steel frame with a blue polymer grip, the STI Grandmaster utilizes the Trubor compensated barrel which is machined from ONE PIECE of 416, Rifle Grade, Stainless Steel. The Trubor is designed to eliminate misalignment of the barrel and compensator bore or movement of the compensator along the barrel threads, giving the shooter a more consistent performance and reduced muzzle flip.

The Grandmaster slide has classic scalloped sides, STI saber-tooth rear cocking serrations, flat top and slide lightening along the rear of the slide. Additional enhancements include STI's RecoilMaster guide rod system, STI stainless steel magwell, stainless steel ambidextrous safeties, stainless steel high rise grip safety, drilled and tapped mag release, and hard chrome finish with color inlay in the engraving. Grandmaster comes complete with either a mounted C-More Railway or a mounted OKO Reflex sight. An STI team shirt, STI cap, and factory grouping target are also included with the Grandmaster. The STI Grandmaster is available in 9x19 (9mm Major) & .38 super.

All Grandmasters come with a STI Team Shirt, and a STI Hat.
