The Steel Master


Inspiration from STI International’s proven race pistol design led to the creation of the STI SteelMaster; a shorter, lighter race pistol for faster target acquisition and reduced muzzle flip and dip. With STI Modular Steel 2011® technology, a 4.15″ classic slide, Trubor compensated barrel system, and STI’s revolutionary RecoilMaster, the STI SteelMaster delivers all the advantages of a full size race pistol in a smaller, lighter, faster reacting, and less violent package. And unlike many other compensated pistols, the SteelMaster runs factory ammo without a hiccup.

Built on the STI Modular Steel 2011® frame with polymer grip, the STI SteelMaster utilizes the innovative Trubor compensated barrel which is designed to eliminate misalignment of the barrel and compensator bore or movement of the compensator on the barrel. The shorter Trubor barrel system in the SteelMaster gives an even greater reduction in muzzle flip and the shorter slide decreases overall slide cycle time allowing the shooter to achieve faster follow up shots. The slide has lightening cuts on the front and rear to reduce weight, and custom “Sabertooth” serrations. With an overall weight of 38.9 oz, the SteelMaster is significantly lighter in weight than full size race pistols. The SteelMaster is mounted with a C-More, 6 minute red dot scope with blast shield and thumb rest. Additional enhancements include aluminum magwell, stainless steel ambidextrous safeties, stainless steel high rise grip safety, STI’s “Spur” hammer, STI’s RecoilMaster guide rod system, & checkered front strap and mainspring housing.

The STI SteelMaster ships with one 126mm Magazine.

*STI is dedicated to ‘Continuing the Evolution of the 1911′ and we periodically implement ‘rolling changes’ to our product specs. While we do try to keep the website and catalog photos as current as possible, there is often a lag between an improvement being implemented and being reflected on our marketing materials. For this reason, all entries are representative only and subject to change without notice.
