Manufacturer’s Description

STI‘s HOST DS is a double-stack 1911-style pistol built on a steel frame with a steel slide, and chambered in 9mm, .45 ACP or 10mm. STI calls it the HOST because it can “host” a suppressor via a threaded bushing barrel and a small classic cut; an optic and/or light via an under-barrel picatinny rail; and an optic via a pre-tapped slide.

Other features include:

  • Either a a 4.15″ or 5″ barrel, both with a thread protector;
  • a 4.5-lb. trigger pull;
  • an ambidextrous thumb safety;
