What Is the Best Size for A Red Dot?
A 3 MOA can provide a more precise point of aim. You need to perform well past 20 yards if you are competing and carrying. A smaller dot obstructs less of the target, suitable for mid to longer-range shooting.
However, if your red dot is a carry weapon, since most self-defense shooting takes place within 10 yards, you need a dot that is simpler to pick and easier to follow through recoil. A 6 MOA dot is larger; hence, it is a more suitable choice. A bigger dot covers more of the target, making it well-suited for fast target acquisition, targets on the move, and close ranges.
What Are the Advantages of a Red Dot Sight
- Easy to See
Red dot sights are easy to see in all lighting conditions. Aside from having manually adjusted illumination settings, some models auto-adjust the dot’s brightness depending on the prevailing lighting. While having the brightest dot possible makes most sense, dimming it can make it look smaller and sharper. This provides a more refined sight picture for enhanced accuracy.
- No Trace
Red dot sights are invisible to everyone else; hence, they won’t compromise your position. This is a huge advantage in tactical situations.
- Variety of Sizes
Red dot sights come with multiple dot sizes. A smaller dot that is 1.5 MOA is fantastic for precision shooting, while a bigger dot that is 6 MOA lets you zero in on a target faster. The industry standard is a 2.5 to 3.5 MOA dot.
- Always On
A red dot sight needs no manual activation after drawing your gun. Although something as ordinary as hitting a button can seem like a gimme under conventional conditions, the action can be surprisingly hard in high-pressure scenarios.
What Are the Disadvantages of a Red Dot Sight?
- Mounting
A red dot sight requires a slide cut either from the factory of aftermarket or a mount crafted to attach to the rear sight dovetail.
- Acquiring the Dot
Finding the dot is not a walk in the park as it seems. Most shooters who are familiar with traditional pistol sights will be substantially slower aiming with a red dot sight.
Conclusion
Hopefully, this review has helped you make a decision for your FN 509. Which red dot are you buying?
