Criteria for Choosing a Red Dot for Glock 19

When it comes to buying a red dot sight for Glock 19, there are plenty of options to pick from. Here are the key things you should take into consideration before settling on any specific product.

Reticle Size

Red dot sights offer quicker target acquisition and boost the shooters precision at close and medium ranges. This is thanks to the crisp point of aim they provide. When choosing a red dot sight reticle, there are two things to consider, individual needs and whether or not you have eyesight problems.

If you have eyesight problems or aging eyes, we recommend that you get an optic that has a large MOA, preferably 6 MOA. On the other hand, you will need a smaller MOA of not more than 3 if precision is what you are looking for in a red dot for Glock 19.

Size and Weight

The next thing to consider is size and weight. While red dot sights are smaller in size, the weight varies from one product to the other depending on the quality of glass and type of materials used. For the best red dots for Glock 19, it is wise to invest in a unit that is ultra-light and compact in form. The lighter the red dot is, the easier it will be to shoot with.


All red dots for Glock 19 run on batteries but the capacity and lifespan of the battery varies from one product to the other. Go for an optic that is powered by a strong battery so it yields reliable performance consistently. The sight should also have multiple battery conservation features to preserve the battery.

Still on battery, consider the placement of the battery compartment. We recommend that you get a product that either comes with a top or side battery compartment. That way, you will find it to replace the battery while the sight is still mounted on the pistol.

Build Quality

The other important thing to consider is build quality. The best red dots for Glock 19 are crafted with premium quality materials such as aluminum or magnesium alloy which are highly resistant to wear. With the quality construction, the optic will be able to stand up to rigors on and off the range.

Furthermore, the sight you choose to buy should also be built ready for use in all environments. It should be waterproof, fog proof and usable in a wide range of temperatures.

Brightness Levels

If you want to push your Glock 19 to its full ability, go for a red dot sight that has multiple brightness levels. Such optics make it easy to acquire targets even in the less-than-ideal lighting conditions. A tip is to get a red dot sight that has 8 or more brightness settings.


  • Can you put a red dot on Glock 19?

Yes. Glock 19 is an optic-ready pistol so you can easily mount a red dot on it. Ensure that the red dot you opt to use has all the features that you need to make your shooting expeditions more rewarding. On top of that, it should also be easy to use and simple to install and remove from the pistol.

  • What MOA is the best for a Glock 19?

It depends. Smaller reticles of 3 MOA and below strike the perfect balance of precision and speed. As such, they are ideal for all shooting applications where speedy target acquisition is vital. On the other hand, large reticles of 4 MOA and above are ideal for seniors with aging eyes or any other user with eyesight problems.

Final Thoughts

Hopefully, this article on the best red dots for Glock 19 has been insightful and of great help to you. With the right red dot sight, you will be able to increase your pistols accuracy no matter the kind of shooting you will be doing.
