Factors to consider when choosing a Best Red Dot for Glock 43x
Compatibility
Before purchasing, ensure the red dot sight is compatible with your handgun, either directly or with an adapter plate. The Glock 43x for example comes with a mounting rail that most red dots will attach to, except for a few which will require a mounting adapter.
Weight
The red dot sight should be appropriately sized for your handgun. A lightweight scope doesn’t add bulk to the firearm which may interfere with the draw speed and the aim.
Reticle size
The red dot sights are available with differently sized reticles, a smaller reticle say 1 to 3 MOA allows for precise aiming over long distances, while a bigger MOA reticle (>3) is easily visible and makes target acquisition faster for close quarters.
Battery life
Consider the battery life of the red dot sight, especially if you intend to use it for defensive carry or long periods without access to replacement batteries.
Brightness
Ample brightness results in better visibility of the reticle both in low light and daylight when it’s bright outside. The best red dot should also have some sort of adjustable brightness, to adapt it to the various shooting conditions.
Price
Different red dots are available for different budgets. Consider what features are most important to you and choose a red dot that offers the best value within your budget.
