Best Pistol Red Dot Sights Buyer’s Guide
As you already know, sights are devices used to aim weapons (think of your Sig Romeo 1), surveying equipment, or illumination tools. They can be one of two things: markers that require alignment with the target, or optics that provide the person using it with a visually amplified image of said target. That being said, there are telescopic sights, iron sights, optics sights, laser sights, and so on.
While we have provided you with a list of the ten handgun sights for accuracy out there, from budget RMRs for budget handguns to more expensive red dot pistol optic sight (or RMR optics) for expensive RMR handguns – whether you need one for competition purposes or for self-defense purposes, we believe that an in-depth knowledge of how to identify and choose a red dot pistol handgun sight for yourself is essential in the event that something happens and you can’t find one of those we have provided.
The size of the red dot sight is a factor that you should consider before you buy one. Sights that have big sizes will interfere with holstering and might not fit with your gun rail. So, be sure to purchase a dot sight that fits your gun’s rail and is also compact.
When looking to buy a red dot sight, be sure to factor its make. All red dot sights are sturdy enough to withstand the recoil of a pistol, but not much more. If you will be using your gun in very rugged conditions and you expect it to drop quite often, you will do well to look for a sight made to withstand such rugged use.
The brightness of your reticle is important for basically two reasons which are; it influences how readily you will see the dot as well as how sharply and clearly the dot will appear. And you don’t need to be told that these two factors will then have a bearing on the accuracy of your shot.
When the dots are not bright enough, they tend to develop a softness around their edges, which renders it hard to make them out. And when they are too bright for the environment in which they are in, they will appear distorted, which will also result in poor targeting.
For this reason, it is important that you buy a dot sight whose reticle is of very high quality. Apart from buying a high-quality reticle, there are other avenues available by which you can also control the brightness of your reticle. These are;
#1 Automatic Brightness
Not all red dot sights have an automatic brightness feature. Those that do, however, come with a light sensor that detects how bright the ambient light is and can, based on that, adjust the reticle’s brightness accordingly to what it determines to be the best for proper targeting. Making use of the automatic brightness feature comes with both advantages and disadvantages.
Its advantage is that it makes aiming ridiculously easy, as you would not have to fiddle with the sight to adjust the brightness and can, therefore, focus all your attention on your target.
All you will be required to do is zero-in on your target, and you can rest assured that the reticle will be visible no matter its color. Apart from this, the automatic adjustment of the brightness will also help you conserve battery life and, thus, ensure its longevity.
The disadvantage to using the automatic brightness, however, is that you will not have a say on how bright the reticle is as the decision will be made for you. And if you are the type that prefers your reticle to be brighter or dimmer than normal, you might find using the automatic brightness feature a little problematic.
#2 Manual Brightness Adjustments
A lot of sights out there come equipped with a manual brightness adjustment. And while this might seem pesky, it is actually the option that most shooting experts prefer as it allows them to retain full control over the brightness settings. Different sights, however, come with different brightness intensities.
The least number of brightness intensities you should go if you are looking to buy a good sight is five (5). Some sights have more than 10 different brightness intensities, however, and this makes it even easier to find a brightness setting that you, the shooter, are comfortable with.
#3 Other Modes
Apart from the brightness mode, there are two other modes that, although uncommon, also come with gun sights. These are; night vision and extreme brightness.
The night vision mode is useful when shooting in extremely low-light, as well as no-light conditions, as they allow you to identify your target regardless.
The extreme brightness mode works in a manner that is opposite to that of the night vision mode. That is, it allows you to aim accurately even in extremely bright conditions, which you normally wouldn’t be able to do.
There are different shapes of reticles available for you to choose from. As such, it is essential that you consider which of them you are most comfortable with before purchasing a sight. If you are buying at a physical store, you might want to test a couple of the sights they have by looking through them before settling on the one that you feel the most comfortable with.
While this particular type of gun accessory is referred to as red dot sight, the truth is that it comes in two different colors. These two colors are green and red. The reticle color that you choose depends on your preference as well as on what you intend to use the gun for.
The green-colored reticle type of red dot sights (or green dot sight) is better for faster spotting of the dot as the human eye is more sensitive to the color green than it is to color red.
If you were making use of the pistol in an environment that contains a lot of the color green (such as an environment with plenty of foliage), you would be better off going with a sight whose reticle is colored red, as the contrast it will provide will help you identify your target faster. In every other scenario, however, you will be better off buying a sight that has a green colored reticle.
When we talk about reticles, we are referring to the aiming point of your red dot sight. That is to say, the crosshairs, which you use to aim at your intended target. It is made of thin lines which meet at the center of the red dot sight.
Different dot sights have different reticles that differ in a myriad number of ways. One of these ways is in their size.
Sometimes, you will come across red dot sight models that seem similar, only to find out that their reticles differ in size. When deciding on which dot sight to buy, it is essential that you base your choice on the size of the reticle size and whether or not it will serve your intended purposes. The unit of measurement of red dot reticle sizes is MOA, which stands for minutes of angle.
As such, a red dot with a small MOA dot size has a small reticle size, while one with a large MOA dot size has a big reticle size. Below are the different types of reticle sizes you will find and what each is best for.
#1 Small Reticle Size
Red dot sights that are considered small usually have an MOA of between 1 and 2. These small sizes allow a shooter to aim accurately over long distances and shoot accordingly.
Red dot sights with small reticle size are mostly for use on AR-15-sized pistols (they are often referred to as AR red dot sights), but then, variations exist that are suitable for use on a pistol.
When you use a small reticle sized red dot, you can rest assured that your aim will be sure even if the distance is long. However, you might find it hard to spot the red dot, especially when in an area where there is a lot of bright light.
#2 Medium Reticle Size
Medium-sized dots are dots that measure between 2 MOA and 4 MOA. These are easier to spot on a target, and they are suitable for aiming at targets that are either within close range or medium range.
This does not mean that medium-sized dots cannot be used to make long-range dots, no. Doing this will, however, require a large amount of skill, and it will definitely be more difficult than using a small-sized dot.
Asides being great for close to medium-range spots, medium-sized reticles are also recommended if you like fast target acquisitions.
#3 Large Reticle Sizes
If a reticle size measures more than 4 MOA, then it falls under the classification of a large-sized dot. Red dots with this kind of reticle size were designed and manufactured for the purpose of acquiring targets fast when shooting at targets that are within a close range. That is to say, when you aim at a target that is within a short distance to you with a large-sized dot, the red dot will instantly become visible.
This renders target acquisition very easy and greatly increases the chances of making accurate shots at close range. The problem with large sized reticles, however, is their size, which essentially occupies most of the space on the red dot sight’s display.
As such, shooting accurately at targets that are farther away, such as those that can be considered as being at a medium-and-long-range away, becomes very hard, if not impossible.
The reason for this is simple: the size of the dot results in most of the target (as well as its surroundings) being blocked. They are, however, perfect for making short-range shots, as already mentioned.
When buying a red dot sight for your angle, ensure you choose one that is lightweight. This is especially important if the pistol you will be using the dot sight with is compact. It is also essential if the pistol it will be used with is to be holstered.
The advice to use a lightweight red dot is not to discredit full-sized dots or to say that they won’t accomplish their purpose; it is simply that lightweight dots offer a bevy of benefits that full-sized dots don’t offer.
For instance, lightweight dots will not in any way influence or affect the balance of your handgun when in use, while full-sized dots are sure to affect the balance. And when your pistol isn’t balanced, you can be sure that your accuracy will be affected, and you will not be able to shoot as effectively as you could.
Yet another factor that deserves careful consideration when it comes to choosing which red dot sight to buy is the battery life of said dot. Over the past couple of years, advances in technology have led to great improvement over how long batteries last such that you can now expect some high-end products to run on the same battery for years as opposed to a couple of hours.
And while a red dot sight is not exactly the kind of product which you will expect to, or will be willing to pay for a battery that can last years for, it is necessary that it comes endowed with a battery that will last a good while.
You will find that most of the red dot sights around use the CR2032 battery type, as it seems to be the best battery type around for this purpose. The lifespan of this battery, however, varies as a result of a number of different factors. The following are ways by which you can ensure that your battery lasts as long as possible:
#1 Choosing The Automatic Brightness Setting
When you choose this setting, the brightness of your sight will automatically adjust in response to the ambient light at the location where you are situated. Choosing this option will help you conserve the dot’s battery, and it will also enhance its longevity.
As such, you will be able to get more use out of it than those who don’t take this precaution.
#2 Going With The Automatic Dimming Option
The automatic dimming option is another step you can take that will result in longer battery life. Activating this feature will result in your sight’s brightness being reduced when the place you are at is brighter than it initially was when you set the brightness level of the sight.
#3 Activating The Automatic Shut-Off Feature
The automatic shut-off feature is an advantageous feature, although it does have its own minor annoyance. This feature results in sight being shut down in the event that it has been on for a specific period of time, which would have been determined beforehand. This feature can also help prolong the life of your battery.
You have two options when it comes to the mode of changing the battery of your sight. You can either go with a sight that comes with a top-access battery hatch, which means that you do not remove the sight before changing the battery.
This has the advantage of ensuring that your sight is still zeroed in after replacing the battery. It, however, has a disadvantage, which is that there might be a problem with the battery fitting correctly or making the correct contact. As such, the red dot might fail at any time, including when you are making use of the pistol.
Alternatively, you have the option of going for a sight that comes with a bottom-access battery hatch, which will require that you remove the sight before you can replace the battery, after which you will then replace the sight and then re-zero it.
Apart from the inconvenience of having to remove, replace, and re-zero your sight, buying a sight with a bottom-access battery has no other disadvantages to point at. Besides, red dot sight batteries last for quite some time, which means that you won’t have to deal with such an inconvenience on a regular basis.
It is essential that you consider which of these two options you are most comfortable with before choosing which red dot sight to buy to avoid being frustrated with your choice in the future.
