The Glock 21 Gen 5, a full-size .45 ACP pistol, is a popular choice for both concealed carry and home defense. But even a great pistol can benefit from upgrades. This in-depth guide explores popular Glock 21 Gen 5 upgrades, focusing on enhancing performance, reliability, and ergonomics. We'll cover everything from simple drop-in parts to more involved modifications. Understanding these upgrades will allow you to tailor your Glock 21 Gen 5 to your specific needs and shooting style.
Essential Glock 21 Gen 5 Upgrades for Enhanced Performance
Improving the performance of your Glock 21 Gen 5 involves focusing on key areas like accuracy, trigger feel, and reliability. These upgrades can significantly transform your shooting experience.
Upgrading the Trigger
The factory Glock trigger, while functional, can be improved for smoother operation and a crisper break. Several options exist:
-
Aftermarket Trigger Connectors: These connectors reduce trigger travel and overtravel, leading to a more precise shot. Popular brands include Ghost, Overwatch Precision, and ZEV Technologies. Choosing the right connector depends on your desired level of trigger pull weight reduction. Note: Always follow local laws and regulations regarding trigger modifications.
-
Trigger Springs: Reducing the trigger spring weight can lighten the pull, but it's crucial to maintain a safe and reliable trigger pull weight. Lighter springs can increase the risk of light strikes, so careful consideration is needed. Experimenting with different spring weights may be required to find your preference.
-
Polishing and Tuning: Professionally polishing the internal trigger components can significantly improve trigger feel and smoothness. This is a more involved process, best left to a qualified gunsmith.
Example: Swapping the factory connector for a Ghost connector is a relatively simple upgrade, offering a noticeable improvement in trigger pull.
Enhancing Accuracy with Sights
Factory Glock sights are serviceable, but aftermarket sights offer significant advantages.
-
Night Sights: Essential for low-light situations, night sights provide enhanced visibility and quicker target acquisition. Tritium night sights are a popular choice. Consider the sight height depending on your co-witnessing preference (e.g., standard, suppressor height).
-
Fiber Optic Sights: These sights offer excellent visibility in daylight conditions, utilizing fiber optics to gather and channel ambient light. They're a cost-effective upgrade for enhanced daytime accuracy.
-
Adjustable Sights: Allow for precise windage and elevation adjustments, crucial for long-range shooting and fine-tuning accuracy.
Improving Reliability with Internal Upgrades
While the Glock 21 Gen 5 is already known for its reliability, certain internal upgrades can further enhance it.
-
Extractors: Upgraded extractors improve reliability, ensuring consistent cartridge extraction even in adverse conditions. Brands like Lone Wolf Distributors offer robust replacements.
-
Firing Pins: Consider a stronger firing pin, especially for use with hotter or more unusual ammunition. A stronger firing pin reduces the risk of light primer strikes. Again, reputable brands are key to ensuring quality and safety.
Ergonomic Upgrades for the Glock 21 Gen 5
Ergonomic upgrades enhance the shooter's comfort and control, leading to improved accuracy and reduced fatigue during extended shooting sessions.
Grip Enhancements
-
Grip Tape: Adding grip tape improves the grip's texture and provides a more secure hold, even with sweaty hands. Various materials are available, offering different levels of grip and texture.
-
Aftermarket Grips: Several companies offer aftermarket grips with improved ergonomics, such as enlarged beavertails or different texturing. These can significantly improve the gun's feel and control.
-
Backstraps: Interchangeable backstraps adjust the grip's size and fit to the shooter's hand, maximizing comfort and control.
Extended Magazine Releases
Factory magazine releases can be difficult to reach, especially for shooters with smaller hands. An extended magazine release allows for quicker and more positive magazine changes under pressure.
Slide Modifications
-
Slide Racks: These aids make manipulating the slide easier, especially for individuals with reduced hand strength or arthritis.
-
Slide Serrations: Upgraded slide serrations provide a more positive grip during slide manipulations, improving control and reliability. Many aftermarket slides offer aggressive serrations for enhanced grip.
Other Glock 21 Gen 5 Upgrades
Beyond the performance and ergonomic upgrades, consider these enhancements:
-
Holsters: A well-fitted holster is essential for both concealed carry and open carry. Choosing a quality holster designed for the Glock 21 Gen 5 with any modifications is crucial for safety and comfort.
-
Ammunition: Experimenting with different ammunition types can help you find the best performing rounds for your specific Glock 21 Gen 5.
-
Lights and Lasers: Adding a weapon light or laser can significantly improve your shooting capabilities in low-light environments.
Conclusion:
Upgrading your Glock 21 Gen 5 allows you to customize the pistol to your individual needs and preferences. Always choose high-quality parts from reputable manufacturers to maintain safety and reliability. Remember to follow all local and federal laws when modifying firearms. By carefully considering the various upgrades discussed above, you can significantly enhance the performance, ergonomics, and overall shooting experience of your Glock 21 Gen 5.
