Factors to Consider when Choosing the Best Red Dot for Glock 43x
The following are some of the key factors you should take into account when shopping for the best red dot for Glock 43x.
Build Quality
Get a red dot sight that features a sturdy and robust construction. With well-made housing, the optic will be able to handle anything you throw at it. Red dot sights for Glock 43x that are most sought-after are made of premium materials such as aluminum alloy.
The model you choose to buy should also be weather resistant for optimal performance even in extreme weather conditions.
Size
The best red dot for Glock 43x is compact in size and lightweight.
Given that the Glock 43x is one of the smallest pistols out there, it will only make sense to pair it with a small optic that doesn’t add any extra weight.
Lens Quality
The quality of the red dot lenses plays a huge role in determining the quality of images generated. The top-notch the glass is, the better the image quality will be.
Furthermore, the optic should have proper lens coatings. This enhances light transmission for clear and bright sight pictures. Lens coatings also shield the optics from corrosion, scratches, and wear.
Reticle Size
The size of the dot reticle varies from one unit to the other. While smaller red dot reticles will offer pinpoint accuracy even at extended ranges, they are less ideal for users with poor eyesight.
In the long run, your ideal reticle size will largely depend on your preference and needs.
Brightness Levels
The brightness levels just like the reticle size, vary greatly from one unit to the other. With so many models to choose from, it is best to get a red dot sight that offers 8 brightness levels or more. This will give you the flexibility to aim confidently in different light settings.
If you plan to use the red dot sight in dismal environments or at night, get a unit that is designed to be night vision compatible.
Battery
The other important feature you should take into account is the battery. Regardless of the activity, and your purpose to use the red dot, it is important that you pick a unit that has a high-capacity battery.
The longer the battery lasts, the more time you get to use it continuously. A longer-lasting battery will also save you the cost of having to buy new batteries for your optic every now and then.
Final Thoughts
Hopefully, you have found this post insightful. Finding the best red dot for Glock 43x doesn’t have to be a task that is daunting, time-consuming, and unpleasant.
When you first identify the activity you plan to use the red dot sight for, it will be easier for you to find the right unit for your needs.
All the red dot sights listed offer the most important features you need to instantly elevate your Glock 42X pistol’s performance no matter the application.
