R3D 2.0 Glock Sights Overview
Our R3D 2.0 tritium sights were engineered to give you a brighter, stronger set of notch and post sights. The front sight features our signature glow dot technology paired with a tritium vial in the center for a vibrant, easy-to-see front sight in bright or low light. The rear sight features larger tritium vials than our standard R3D sets, making them easier to see in low light. The rear also features a serrated face and lens to reduce glare in bright lighting conditions. The Black Nitride surface finish provides enhanced corrosion resistance, making the set ideal for EDC use in sweaty or humid environments. This set requires 50% less force for installation, thanks to the lead-in edge and crush zone on the underside of the rear sight, making it ideal for DIY installation.
R3D Glock Sights Overview
Our R3D tritium sights were our first 3-dot notch and post product. The front sight features a green or orange photoluminescent glow dot surrounding a tritium vial in the center. The combination gives you a vibrant front sight in bright light and a glowing sight in low light. The rear sight has two tritium vials for low-light indexing and features a simple blacked-out face to contrast with the front sight. The rear sight features a wide notch for fast sight alignment and easy indexing with the front sight in any lighting conditions.
Minimalist Walther PDP Sights Overview
Our Minimalist sights offer a traditional notch and post sight picture with a serrated non-tritium rear. The anti-glare, blacked-out rear has a wide notch to draw your eye to the front sight. The front sight is equipped with tritium in the center, surrounded by our glow dot technology. The glow dot is photoluminescent, absorbing ambient light to provide a gentle glow in low-light conditions.

Glock A-CUT with COA Optic
R3D 2.0 sights for Glock A-Cut are designed for easy installation, making it suitable for DIY enthusiasts. These sights feature a sleek, low-profile design that minimizes obstructions in the optic window while enhancing durability. Equipped with tritium, the sights provide visibility in all lighting conditions. They include a glow dot for quick target acquisition and easy front sight differentiation.

The wide-notch rear sight has an anti-reflective finish, ensuring a clear sight picture. The rear sight is longer than the factory option, which helps prevent dirt buildup between the sight and the optic lens. Additionally, the XS rear sight is designed to sit flush, offering a cleaner look and reducing the chance of snagging. This sight set is perfect for Glock users who value performance and convenience.
Upgrade Your Sights
Factory Glock sights often fall short when it comes to durability and visibility. Made of plastic, they can break or shift during use, and their design lacks easy visibility in high-stress or low-light scenarios. XS Sights are constructed from steel, ensuring they are durable and withstand the wear and tear of training. Factory sights can also be difficult to see in different scenarios. XS Sights addresses this by increasing the size of the front sight, allowing for your eyes to easily pick it up in high-stress scenarios, and by adding tritium into the sight bodies. The tritium emits a gentle glow that guides your eye to acquire the small light source, making it easily visible in low-light scenarios. Take your Glock to the next level. XS Glock night sights are the perfect upgrade for enhanced visibility, durability, and reliability. Stock up on the best Glock 19 sights for self-defense and experience the XS Advantage!

XS Glock sights can be easily installed with sight pusher tools or a hammer and punch.
