Things to Look for in a Red Dot for Glock 43X MOS
Buying a red dot for Glock 43X MOS is not something you do in a hurry. When making your selection, take into account these important features.
Size and Weight
In red dot sights, size and weight go hand in hand. The Glock 43X MOS is a very compact handgun. This calls for a red dot sight that is equally small in size. Additionally, the best red dot for Glock 43X MOS should have a lightweight construction so as not to add any weight on the handgun.
Reticle
The reticle size in red dot sights is measured in MOA. Red dot sights that are built with a large MOA are ideal for users with aging eyes or poor eyesight. Such reticles are easy to spot and only ideal for close range applications.
On the other hand, red dot sights with smaller MOA reticles are slightly harder to spot compared to the larger counterparts, but the best in terms of precision and speed. If accuracy and speed is what you need for your handgun, go for a device that has a small red dot of 4 MOA and below.
Battery Life
The next thing to take into account is battery life. The longer the battery life a red dot sight has the better. It will keep the optic running for hours and minimize the odds of it failing in the middle of use.
In addition to long battery life, consider the placement of the battery compartment. A tip is to get a device that has a top or side placed battery compartment. Such red dot sights allow for easy battery change while the optic is still mounted on the handgun.
Overall Build Quality
Build quality of a red dot sight is the other important thing to consider. A tool that is built with top-notch materials will withstand rough use and offer many years of reliable performance. Such optics are either made from magnesium alloy or aircraft quality aluminum.
The best red dot for Glock 43X MOS should also be built ready for use in any environment. This means that the optical tube should be fog proof, waterproof and dustproof as well.
Optics Coating
If the red dot sight doesn’t provide a clear view of the targets, it will be hard for the shooter to know where to place the shot. This is where optical coatings come in to play. A red dot sight with premium anti-reflective lens coatings will reduce internal light reflection that causes glare. As a result, more light is transmitted and the red dot sight yields bright and clear image views.
