Frequently Asked Questions

What was the STI 2011 pistol's intended military application?

The STI 2011 features a 5-inch cone profile barrel (eliminating the bushing), a full-length guide rod, accessory rails, ambidextrous safeties, and BoMar adjustable tritium night sights. It was chambered in .40 S&W and designed for higher capacity magazines.

Where did the rejected STI 2011 pistols end up?

After being rejected by Delta Force, the STI 2011 pistols were returned to STI International and subsequently sold on the civilian market as used firearms. Many buyers were unaware of their elite military history.
