Since the early 2000s, they have been steadily gaining in popularity for use on pistols. Optics technology is ever-advancing, so the conversation continues to evolve about what kind of sights are best to use in different situations. If you&#8217;re trying to decide whether or not to add a Red Dot Sight to your pistol, it is important to know the different types and how they each function. Here, we discuss the basics of Red Dot Sight (RDS) varieties and applications.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Red Dot Sight Terminology<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The term \u201cRed Dot Sight\u201d covers a wide range of optics. Generally speaking, it (or the acronym RDS) refers to any kind of sight that displays an illuminated shape as the aiming point. The shape can come in various colors and shapes. Often shooters use a dot in their RDS, but it can also be displayed as a chevron, cross-hairs, etc.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Other terms you might run into:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\"><strong>Red Dot Scope: <\/strong>this means the same as \u201cRed Dot Sight.\u201d<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\"><strong>Eye relief:<\/strong> is the distance between your eye and the ocular lens when looking through the scope.<\/span><\/li>\n<li><span style=\"font-weight: 400;\"><strong>Reticle:<\/strong>&nbsp; the crosshair or aiming point of your scope<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\"><strong>Focal Plane:<\/strong> This is where the reticle is installed.

They are less forgiving on eye relief than the reflex sight, which requires your eye to be in the same spot each time. Most prism sights have an etched reticle, so if the battery malfunctions you\u2019ll still be able to use it to focus in on your target. The fixed-power magnification (usually up to 3.5X) makes them unsuitable for long-range shooting for some shooters, though this is, of course, dependent upon the individual shooter, the weapon, and how one defines &#8220;long-range.&#8221; Some have posited that prism sights are best suited for survival situations since they can be used without battery power; others dismiss this notion, given the successful use of prism sights on multiple platforms for many reasons (including combat use).&nbsp;&nbsp;<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Here are a couple of examples of the reticles in prism sights.&nbsp;<\/span><\/p>\n<figure id=\"attachment_7519\" aria-describedby=\"caption-attachment-7519\" style=\"width: 900px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-7519 lazyload\" data-src=\"https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2019\/07\/Prism-reticle-Primary-Arms-green-red.png\" alt=\"Red Dot Sight, Prism sight, reticle\" width=\"900\" height=\"432\" data-srcset=\"https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2019\/07\/Prism-reticle-Primary-Arms-green-red.png 900w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2019\/07\/Prism-reticle-Primary-Arms-green-red-300x144.png 300w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2019\/07\/Prism-reticle-Primary-Arms-green-red-768x369.png 768w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2019\/07\/Prism-reticle-Primary-Arms-green-red-400x192.png 400w\" data-sizes=\"(max-width: 900px) 100vw, 900px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 900px; --smush-placeholder-aspect-ratio: 900\/432;\" \/><figcaption id=\"caption-attachment-7519\" class=\"wp-caption-text\">Prism reticles.

This is largely due to the fact that with a red dot sight the shooter is able to focus on the target instead of transitioning focus between the target and the sight. The image below from recoilweb.com demonstrates the difference in focus between a red dot sight and a traditional iron sight.<\/span><\/p>\n<figure id=\"attachment_7521\" aria-describedby=\"caption-attachment-7521\" style=\"width: 675px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-7521 lazyload\" data-src=\"https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2019\/07\/Focus-RDS-VS-Iron-Sights.jpg\" alt=\"Red Dot Sight vs Iron Sight - point of focus\" width=\"675\" height=\"450\" data-srcset=\"https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2019\/07\/Focus-RDS-VS-Iron-Sights.jpg 675w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2019\/07\/Focus-RDS-VS-Iron-Sights-300x200.jpg 300w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2019\/07\/Focus-RDS-VS-Iron-Sights-150x100.jpg 150w, https:\/\/gunmagwarehouse.com\/blog\/wp-content\/uploads\/2019\/07\/Focus-RDS-VS-Iron-Sights-400x267.jpg 400w\" data-sizes=\"(max-width: 675px) 100vw, 675px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 675px; --smush-placeholder-aspect-ratio: 675\/450;\" \/><figcaption id=\"caption-attachment-7521\" class=\"wp-caption-text\">Image source: RecoilWeb.<\/figcaption><\/figure>\n<p>Another advantage to the red dot sight is the potential for heightened situational awareness. If your RDS isn&#8217;t magnified you can keep both of your eyes open more easily, which means you have a greater field of view (and thus better-maintained peripheral vision). With your eyes open, you can also move from target to target more easily. Shooting while moving is easier, too. Some say that one-handed manipulation is easier with an RDS.<\/p>\n<p>Compared to iron sights, night or low-light shooting is easier with red dot sights. Even so, target identification can still be an issue in low-light situations, so be sure to adjust the brightness of your dot so that it doesn&#8217;t block out the target.<\/p>\n<p>Finally, red dot sights are easier on the eyes. Individuals with poor eyesight report improved distance shooting while using them. The eye relief is more forgiving, and older people indicate that green dots are especially good at helping them shoot more accurately at longer distances.<\/p>\n<h3>Disadvantages<\/h3>\n<p>Most of the disadvantages are mechanical in nature. The glass can break, or the battery might fail. You might lose your zero. Debris or water might block the LED, as described in the Water is Wet, Red Dots Break article by Dave Merrill at Recoil. If you plan to use a red dot sight with a pistol, plan on extensive training so that you develop a natural reflex in your presentation. You should train with the goal of quickly obtaining a perfect presentation (remembering that practice doesn&#8217;t make perfect, <em>perfect <\/em>practice makes perfect).<\/p>\n<h2>Before You Buy a Red Dot Sight<\/h2>\n<p>There are a lot of things to consider before purchasing a red dot sight. What features are you looking for? How do you intend to use it? Here are a few things to think about.<\/p>\n<h3>Reticle<\/h3>\n<p>What kind of shape do you want? Do you want a dot, or do you prefer crosshairs or other reticle options? What size do you want the dot, or reticle, to be? Small dots can help with improved shooting accuracy, but they can be hard to find in bright light. On the flip side, larger dots are easier to see. However if they are too big they can cover up your target, especially at long distances.<\/p>\n<p>Window size is also a consideration. Larger windows can make it easier to see the dot, but perhaps you prefer a tighter field of view to aim with.<\/p>\n<p><span style=\"font-weight: 400;\">Window shape can also influence the efficiency of your Red Dot Sight. The human brain is quite good at centering a round dot inside a round tube this leads to increased speed and precision.<\/span><\/p>\n<p><strong>Durability<\/strong><\/p>\n<p><span style=\"font-weight: 400;\">Depending on the application of your RDS you may want to spend some time <\/span><span style=\"font-weight: 400;\">researching<\/span><span style=\"font-weight: 400;\"> sights that are more durable. Keep in mind that the size of the caliber may not have the most impact on durability. A relatively mild recoiling 9mm handgun may induce much more stress on the sight than the recoil of a more powerful .308 rifle. Why? Because most handgun-mounted Red Dots are mounted on the pistol&#8217;s slide, which reciprocates.&nbsp;<\/span><\/p>\n<h3>Battery<\/h3>\n<p>You should take some time to evaluate the battery requirements of the different red dot sights that you are looking at. Do you need one that automatically shuts off after a period of non-use? Does the entire optic need to be removed from the firearm when you change the battery? If so, you will have to zero it in after each battery change. How easy will it be to obtain replacement batteries?<\/p>\n<h3>Settings<\/h3>\n<p>Red dot sights come with various adjustable settings. Do you want to be able to manually adjust the brightness, or do you want it to automatically adjust? If you choose a manually adjusted RDS, would you be able to adjust it during high-stress situations? Also, how difficult or easy is it to zero in the red dot?<\/p>\n<h3>Mount<\/h3>\n<p>What kind of firearm are you planning to mount your new RDS to? A hand-gun sized sight can work on a rifle, but the dot will be smaller and the battery life will be shorter. Do you want short or tall optic? Some shooters prefer the shorter type because they find it easier to put the dot on the target. However, other shooters prefer taller optics with larger windows.<\/p>\n<p>Will your RDS share space with other accessories? Make sure it fits the space available. Check to see if the sight&#8217;s batteries are compatible with other accessories you may be using.<\/p>\n<p>Finally, when making a choice about which red dot sight to purchase for your firearm, make sure to get a mounting system that matches it.
