Factors to Consider When Looking for the Best Glock Reflex Sights

Red Dot Sights

There are three different types of red dot/reflex sights. These are namely:

  • LED
  • Tritium
  • Dual Tritium

You might be thinking that the Dual Tritium option is the best since it’s a dual dot and hence, the best of both worlds…not so fast. The great thing about tritium sights is that they don’t require any batteries to operate since they rely on tritium tubes that have a half life of around 10 years. As such, there would be no concern for battery life at all.

That said, tritium sights might not pick up the dot under some light conditions and hence, they are less reliable than the LED red dot sights. If you are looking for red dot sights that would work 24/7, the better option would be to keep things simple and get yourself an LED red dot sight. The only concern you might have is its battery life and that’s about it. A great battery will last you at least a year on proper red dot sights, if not more.

MOA Dot Size

Which MOA dot size is the best for you? If you didn’t know, MOA on reflex sights are basically the size of your red dot. The rule of thumb here is – the bigger your MOA (Minute of action), the bigger the dot.

It’s a pretty common misconception that bigger dots (6.5 – 9 MOA) will help you with your aim and target acquisition significantly. If things were that simple, the world would be a better place. But this isn’t the case. One of the main downsides of having a bigger dot is that you will find it difficult to hit precisely at a distance as the size of the dot will be covering your target.

Most shooters will go for 3 MOA dots or smaller as it can do almost everything a bigger MOA dot can do and also allows you to take precision shots at a distance. If you are worried that might not be visible enough for you, simply dial up the brightness setting.


Every Glock MOS will come cut out for the red dot sight so you won’t have to make any additional modifications to it. For other handguns, it will depend on the model. Since this is an article on the best Glock reflex sights, we will stick to Glocks.


The lower end red dot sights (below $100) are usable and will be able to hold their zero but they are not durable and not reliable. You won’t know when it’s going to lose its zero or break down as you shoot on the shooting range or hunt outdoors. As such, it will be a good idea for you to invest more in a great Glock reflex sight for your firearm.
