What are Glock 43X MOS Red Dots?

Glock 43X MOS red dots are mini red dot sights that are designed for use with the popular Glock 43X pistol. The “MOS” in the name stands for “Modular Optic System,” which means that these sights can be easily added or removed from the gun as needed. 

This is a great feature for those who want the option to switch between using iron sights and a red dot sight, or for those who want to use multiple red dot sights on different guns.

Do You Need a Glock 43X MOS Red Dot?

If you’re planning on using your gun for self-defense or competition shooting, then a red dot sight can be a valuable addition. Red dot sights offer several advantages over iron sights, including:

Faster Target Acquisition

Red dot sights also allow you to acquire targets faster than iron sights. This is because the red dot is always in the center of the sight, so you do not have to line up the front and rear sights with the target. This can be especially beneficial in self-defense situations where time is of the essence.

Unlimited Eye Relief

Another benefit of red dot sights is that they offer unlimited eye relief. This means that you can place the red dot anywhere on the sight and still see it clearly. This is unlike iron sights, which require you to place your eye in a specific spot in order to see the front and rear sights clearly.

Easy to Use

Red dot sights are also very easy to use. Even if you’ve never used one before, it’s easy to get the hang of it. Just place the dot on the target and pull the trigger.

Are There Any Drawbacks to Using A Glock 43X MOS red dot?

While there are many advantages to using a red dot sight, there are also a few drawbacks. The biggest drawback is that red dot sights can be more expensive than iron sights. Additionally, red dot sights can be damaged more easily than iron sights and they require batteries, which means you’ll need to keep an eye on the power level.

Common Myths about the Glock 43X MOS Red Dots

The Glock 43X MOS red dot is a great option for those who want to upgrade their gun with a red dot sight. However, there are some common myths about this type of sight that needs to be dispelled. Here are 5 of the most common myths about the Glock 43X MOS red dots:

Again, this is not true! While red dot sights are often used for short-range shooting, they can actually be quite effective at long range as well. With a little practice, you’ll be surprised at how accurately you can shoot with a red dot sight at longer distances.

Myth: It’s difficult to find replacement parts for red dot sights.

This used to be true but it’s no longer the case. These days, there are many companies that make replacement parts for red dot sights so it’s easy to find what you need if something breaks or needs to be replaced.

Myth: You have to pay a lot of money to get a good quality red dot sight.

While it’s true that you get what you pay for, you don’t necessarily have to spend a lot of money to get a good quality red dot sight. There are many great options available at reasonable prices so do your research and shop around before making a purchase.
