The Trijicon RMR Type 2 3.25 MOA is one of the best red dot sights for the Glock 19 Gen 5. It delivers fast target acquisition, excellent durability, and reliable performance in different shooting conditions. Whether you use your Glock for concealed carry, home defense, range training, or hunting, this optic offers the speed and precision many shooters want. In addition, its compact design fits well on the Glock 19 Gen 5 without adding unnecessary bulk.

Built with a grade 5 titanium housing, this optic is designed for hard use. As a result, it handles daily carry, range sessions, and rough conditions with ease while still remaining lightweight.
The sight uses Holosun’s Multi Reticle System, which gives shooters more flexibility. You can switch between a 2 MOA dot, a 32 MOA circle, or both together depending on your shooting preference. The circle helps guide your eye quickly during close range shooting, while the precise dot improves accuracy at longer distances.
