STI‘s HOST SS 5.0 is a single-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:
- A 5″ barrel with a thread protector;
- a 4.5-lb. trigger pull;
- an ambidextrous thumb safety;
- tall, fixed, tritium, suppressor sights;
- VZ Alien black gray grips;
- a Dawson Precision tool-less guide rod;
- a slim magwell;
- a black diamond-like-carbon (DLC) finish; and
- two magazines with extended basepads.
