The Glock 19 is a ubiquitous handgun, favored by law enforcement, competitive shooters, and civilians alike. A critical component of accuracy and effective shooting is the rear sight. While the factory Glock rear sight gets the job done, many users find upgrading to be a worthwhile investment for improved performance and personalized feel. This guide explores the world of Glock 19 rear sights, delving into factory options, popular aftermarket upgrades, and factors to consider when choosing the right sight for your needs.
Understanding the Factory Glock 19 Rear Sight
The standard Glock 19 rear sight is a relatively simple, low-profile design made of polymer. It offers a consistent, U-notch shape, providing a clear sight picture for rapid target acquisition. While functional, its polymer construction can be prone to wear and tear over time, potentially affecting accuracy. The low profile can also be less desirable for certain shooting disciplines or individual preferences.
Popular Aftermarket Glock 19 Rear Sight Upgrades
The aftermarket offers a vast array of Glock 19 rear sights, catering to a wide range of shooting styles and needs. Here are some of the most popular options and the benefits they offer:
1. Night Sights: Enhancing Low-Light Visibility
Night sights are a popular upgrade for self-defense and law enforcement applications. These sights incorporate tritium vials or luminescent materials to glow in low-light conditions, significantly improving target acquisition in challenging environments. Popular brands such as Trijicon, Ameriglo, and Meprolight offer various night sight options for the Glock 19, often featuring different designs and brightness levels. Choosing the right night sight depends on individual preferences and the specific lighting conditions the gun will be used in.
2. Fiber Optic Sights: Bright and Precise
Fiber optic sights utilize a fiber optic rod to channel ambient light to a bright aiming point. These sights excel in daylight conditions, offering an incredibly bright and clear sight picture. Many shooters find fiber optic sights incredibly intuitive and easy to use, facilitating faster target acquisition. Some manufacturers even combine fiber optic elements with tritium vials for superior performance in all lighting conditions.
3. Adjustable Rear Sights: Fine-Tuning for Precision
Adjustable rear sights allow for precise windage and elevation adjustments, crucial for shooters striving for peak accuracy. These sights usually feature small adjustment screws that allow the shooter to fine-tune the point of impact. Adjustable sights are particularly beneficial for competitive shooters or those who require the utmost precision from their handgun.
4. Suppressor Height Sights: Accounting for Suppressor Use
If you use a suppressor on your Glock 19, standard sights may be obstructed. Suppressor height sights are designed to provide a clear sight picture even with a suppressor attached. These are essential for maintaining accuracy and aiming effectively when shooting suppressed.
Choosing the Right Glock 19 Rear Sight: Factors to Consider
Selecting the ideal rear sight for your Glock 19 involves careful consideration of several factors:
- Your Shooting Discipline: Competitive shooters might prioritize adjustable sights for precise adjustments, while self-defense users might favor night sights for low-light visibility.
- Lighting Conditions: Night sights are paramount for low-light environments, while fiber optic sights excel in daylight.
- Personal Preference: Sight preference is subjective. Consider handling different sight types to determine what feels most comfortable and intuitive.
- Budget: Prices vary significantly depending on the brand, materials, and features.
Installation and Maintenance
While installing a new rear sight is generally straightforward, it’s recommended to consult a qualified gunsmith, especially for the first-time installer, to ensure correct and safe installation. Regular cleaning and maintenance will prolong the lifespan of your sights and maintain their accuracy.
Conclusion
Upgrading your Glock 19 rear sight can significantly enhance your shooting experience. By carefully considering your individual needs and preferences, you can choose a sight that optimizes accuracy, enhances visibility, and provides a personalized feel for your firearm. Remember to always prioritize safety and consult a professional if you have any doubts about installation or maintenance.
