5 Best Holosun Red Dot for Glock 19 Gen 5
1)HOLOSUN 407/507COMP Series 6
The HOLOSUN 407/507COMP Series 6 is an excellent red dot sight for the Glock 19 Gen 5, especially for shooters who want a large viewing window, fast target acquisition, and highly customizable reticle options. Whether you are using your Glock for competitive shooting, range practice, or defensive training, this optic delivers impressive speed and accuracy while maintaining the rugged reliability Holosun is known for. Its durable aluminum construction and long battery life make it a dependable upgrade for both experienced and newer pistol owners.
One of the biggest advantages of the 407/507COMP Series 6 is its Competition Reticle System (CRS). Unlike standard red dot sights that offer only a single aiming point, this model includes a precision 2 MOA green dot, along with 8 MOA, 20 MOA, and 32 MOA circles. Shooters can select individual reticles or multiple combinations depending on their shooting style and the type of target engagement. The larger circle options make it easier to acquire the reticle during rapid movement, while the 2 MOA dot provides excellent precision for longer distance shots.

Best Holosun Red Dot for Glock 19 Gen 5 Advantages
Improved Target Acquisition
A quality red dot sight allows shooters to acquire their target much faster than traditional iron sights. Instead of aligning the front and rear sights, you simply place the illuminated reticle on the target. This makes it easier to engage targets quickly, especially during defensive situations, competitive shooting, or rapid drills where every fraction of a second matters.
Greater Shooting Accuracy
A clear, well defined aiming point helps improve shot placement at both short and moderate distances. Whether using a simple dot or a combination reticle, the optic enables more precise aiming while reducing alignment errors that are common with iron sights. This can lead to tighter shot groups and increased confidence during practice and real world applications.
