This review of the Rock Island STK100 highlights its all-metal construction, featuring a steel slide and aluminum frame, distinguishing it from polymer-based competitors. The reviewer, Justin Opinion, notes its Glock 17 footprint, optic-ready slide, and a trigger that breaks cleanly around 5 pounds, which he considers a significant improvement over standard Glock triggers. While generally positive about its handling and accuracy, he cautions about the aluminum grip becoming uncomfortably hot when exposed to direct sunlight on a warm day.

Quick Summary

It shares a Glock 17 footprint, is optic-ready, and boasts a crisp 5-pound trigger considered superior to standard Glock triggers. A key consideration is that its aluminum grip can become very hot in direct sunlight.
