Reviews from Users
- “This is a great sight for the money especially when comparing it to Trijicon’s new RMRcc at twice the price. Compact, durable, and great sight picture for a small optic. It’s neat to have the dot, circle dot, and circle as options – however I do prefer the circle dot reticle.” – Supbraddah, OpticsPlanet
- “Very good optic. UPDATE! 07/16/2023- Battery life issue!! The red dot was so far to the right out of the box that it reached it’s mechanical limits of adjustability. This is my second Holosun 507k as I had the V1 and it lasted 10 rounds. I contact acted Holosun’s Instant Messenger on Facebook and had the reticle recentered. However, the battery life seems to be much shorter than advertised. I’ve had it for about 6 months and the battery is already low.” – citcust, Amazon

What is Red Dot Sight?
A red dot sight is a type of optic device commonly used in firearms, including handguns, rifles, and shotguns. It is designed to provide the shooter with a simple and intuitive aiming solution. Red dot sights use a red dot or reticle as an aiming point, which is projected onto a clear lens.

The red dot reticle appears as a small illuminated dot that is superimposed onto the target when the shooter looks through the sight. Unlike traditional iron sights that require aligning front and rear sights, red dot sights allow for quick and easy target acquisition. The shooter simply places the red dot on the desired point of impact and pulls the trigger.
The technology behind red dot sights typically involves an LED (light-emitting diode) or a laser diode to project the red dot onto the lens. The brightness of the dot can usually be adjusted to suit different lighting conditions. Some red dot sights also offer multiple reticle options, such as different dot sizes or reticle shapes.
Red dot sights are popular due to their ease of use, rapid target acquisition, and enhanced accuracy. They are particularly useful in scenarios that require quick target acquisition, such as competitive shooting, tactical applications, or self-defense situations.
It’s important to note that red dot sights are not magnifying optics like telescopic scopes. They provide a 1x magnification, meaning the target appears the same size as it would with the naked eye. This feature allows for both-eyes-open shooting, which helps maintain situational awareness and peripheral vision.
Red dot sights are available in various sizes and configurations to accommodate different firearms and shooting applications. They can be mounted directly on the firearm’s slide or receiver, or on a separate mount compatible with the firearm’s accessory rail.
Overall, red dot sights provide shooters with a fast, intuitive, and accurate aiming solution, making them a popular choice for many firearm enthusiasts and professionals.
Why Your M&P Shield Plus Need Red Dot Sight?

There are several reasons why a Shield Plus handgun can benefit from a red dot sight:
Improved Target Acquisition
A red dot sight allows for faster and more precise target acquisition compared to traditional iron sights. The illuminated red dot provides a clear aiming point, making it easier to align the sight with the target quickly. This is particularly beneficial in self-defense situations or competitive shooting where split-second reactions are crucial.
Enhanced Accuracy
Red dot sights can help improve accuracy by providing a consistent aiming point. With a red dot sight, shooters can focus on the target and place the dot precisely where they want to hit. The dot remains in focus, eliminating the need to align front and rear sights, reducing potential sighting errors.
Increased Shooting Speed
Red dot sights enable shooters to shoot with both eyes open, maintaining situational awareness while keeping the target and the dot in view. This improves reaction times and allows for faster follow-up shots, making it particularly useful in dynamic shooting scenarios.
Versatility
A red dot sight on the Shield Plus adds versatility to the firearm. It allows for easier target engagement at various distances, from close-quarters engagements to medium-range shots. The shooter can quickly transition between targets without needing to re-align sights, providing a significant advantage in competitive shooting or self-defense situations.
Low-Light Performance
Many red dot sights offer adjustable brightness settings, including night vision compatibility. This makes them ideal for low-light or night-time shooting scenarios, where traditional iron sights may be challenging to see or align properly.
Ease of Use
Red dot sights are generally easier to use than iron sights, especially for shooters with vision impairments or those who struggle with focusing on the front and rear sights simultaneously. The single, illuminated dot simplifies the aiming process, making it more accessible and intuitive for shooters of various skill levels.
Personalization and Customization
Red dot sights provide an opportunity for customization and personalization of the Shield Plus handgun. They come in various sizes, reticle options, and styles, allowing shooters to choose a sight that aligns with their preferences and shooting needs.
Factors to Consider When Choosing a Red Dot Sight for M&P 9 Shield Plus

When choosing a red dot sight for your Shield Plus handgun, there are several important factors to consider. These factors will help you find the best red dot sight that suits your needs and enhances your shooting experience. Here are the key factors to consider:
1. Compatibility with Shield Plus
Optics-ready design: Ensure that the red dot sight is compatible with the Shield Plus and can be easily mounted on its slide.
Mounting options and compatibility: Check if the sight is compatible with popular mounting systems like the Shield RMSc, Shield RMS, or other industry-standard mounting options.
2. Reticle Options
Dot size and shape: Consider the size and shape of the reticle dot. Different shooters may have preferences for smaller or larger dots, as well as different reticle shapes (e.g., single dot, dot with a surrounding circle, etc.).
Reticle color options: Some red dot sights offer multiple reticle color options, such as red, green, or even blue. Choose a color that suits your preference and provides good contrast against the target.
3. Durability and Construction
Materials used: Look for red dot sights constructed with durable materials like aluminum or steel for longevity and reliability.
Waterproof, shockproof, and fog-proof features: Ensure the sight is designed to withstand various environmental conditions, including being waterproof to withstand rain or submersion, shockproof to handle recoil, and fog-proof to prevent internal fogging in different temperatures.
4. Battery Life
Type of battery and its longevity: Consider the type of battery the red dot sight uses (e.g., CR2032, CR1632) and how long it typically lasts before needing replacement or recharging.
Power-saving features: Some red dot sights come with features like automatic shut-off or motion sensors to conserve battery life when the sight is not in use.
5. Brightness Settings
Adjustable brightness levels: Look for a sight with a wide range of brightness settings, allowing you to adapt to different lighting conditions.
Night vision compatibility: If you plan to use night vision devices, ensure the red dot sight has compatible brightness settings to work effectively with them.
6. Optical Performance
Clarity and resolution: Consider the quality of the lens and coatings used in the sight, as well as the overall clarity and resolution of the reticle.
Parallax and eye relief: Look for a red dot sight with minimal parallax, meaning the reticle stays on target regardless of your eye position. Also, consider the eye relief distance, which affects comfort and ease of acquiring the reticle.
7. Price Range
Budget considerations: Set a budget range and consider red dot sights within that range. Prices can vary significantly based on brand, features, and overall quality.
Value for money: Assess the overall value offered by the red dot sight in terms of its features, performance, and durability compared to its price.
By considering these factors, you can narrow down your options and find the best red dot sight for your Shield Plus handgun that meets your specific requirements.
