The Glock 20 Gen 4, chambered in the potent 10mm Auto cartridge, is a favorite among enthusiasts for its power and reliability. But even a great pistol can benefit from upgrades. This in-depth guide explores popular Glock 20 Gen 4 upgrades, helping you tailor your firearm to your specific needs and shooting style. We'll cover everything from enhancing accuracy and ergonomics to boosting reliability and customization.
Understanding Your Glock 20 Gen 4
Before diving into upgrades, it's crucial to understand the strengths and weaknesses of your Glock 20 Gen 4. This generation features improvements over its predecessors, including:
- Improved Ergonomics: The Gen 4 boasts a more aggressive grip texture, offering enhanced control and reduced recoil.
- Ambidextrous Magazine Release: This feature is a welcome addition for both right and left-handed shooters.
- Interchangeable Backstraps: These allow you to customize the grip size for a perfect fit.
- Enhanced Durability: Glock's reputation for reliability is well-deserved, and the Gen 4 is no exception.
However, some shooters find areas for improvement. The factory sights, for instance, can be less than ideal for precise shooting, and the trigger can feel somewhat stiff for some. Let's explore how upgrades can address these and other aspects.
Top Glock 20 Gen 4 Upgrades: Accuracy and Precision
Improving accuracy is often a top priority for Glock 20 Gen 4 owners. Several upgrades directly address this:
1. Aftermarket Sights
Factory Glock sights are functional, but many shooters upgrade to higher-quality sights for improved visibility and accuracy. Popular options include:
- Night Sights: These offer superior visibility in low-light conditions, crucial for self-defense situations. Brands like Trijicon and Ameriglo offer excellent choices.
- Fiber Optic Sights: These utilize bright fiber optic rods for enhanced visibility in various lighting conditions. They are often more affordable than night sights.
- Red Dot Sights (RDS): Mounting an RDS on your Glock 20 Gen 4 using an appropriate adapter plate significantly improves target acquisition speed and accuracy, especially at longer ranges. This requires careful consideration of co-witnessing heights.
Case Study: A shooter reported a significant improvement in their grouping accuracy after replacing the factory sights with Trijicon HD night sights. The improved visibility allowed for faster target acquisition and more precise shot placement.
2. Trigger Upgrades
The Glock trigger is known for its reliability, but its somewhat gritty feel and long pull can be improved. Popular trigger upgrades include:
- Trigger Connectors: These reduce trigger travel and reset, resulting in a crisper and shorter trigger pull. However, proceed with caution, as improper installation can affect the firearm's safety.
- Trigger Springs: Lighter trigger springs can reduce trigger pull weight, although this should be balanced with the need to maintain a safe and reliable trigger mechanism. Modifying the trigger spring without proper knowledge is strongly discouraged.
Important Note: Always consult with a qualified gunsmith before undertaking any trigger work. Incorrect modifications can severely compromise the firearm's safety and reliability.
3. Barrels
While the factory barrel is reliable, aftermarket barrels can offer improvements in accuracy and durability. High-quality aftermarket barrels often feature tighter tolerances and superior materials. However, ensure compatibility with your specific Glock 20 Gen 4 model.
Glock 20 Gen 4 Upgrades: Enhancing Ergonomics and Control
The Gen 4 already offers improved ergonomics, but upgrades can further enhance comfort and control:
1. Grip Enhancements
Several options improve grip texture and feel:
- Talon Grips: These are rubberized grip overlays that significantly improve the texture and feel of the grip, offering better control, especially during recoil.
- Stippling: This involves texturing the grip surface to enhance grip and reduce slippage. This can be done professionally or DIY with careful attention to safety.
2. Extended Magazine Releases
Extended magazine releases make it easier to manipulate the magazine release, particularly when wearing gloves. They can be made of various materials, like aluminum or polymer.
3. Magwell
A magwell improves reloading speed by guiding the magazine into the well during reloads. This is a particularly useful upgrade for competition shooters or those involved in self-defense.
Glock 20 Gen 4 Upgrades: Reliability and Maintenance
While the Gen 4 is reliable, several upgrades can further enhance its dependability:
1. Upgraded Extractor Spring
A slightly stiffer extractor spring can improve reliability, especially with hotter 10mm loads. This ensures consistent cartridge extraction. However, this upgrade requires care and attention to avoid over-springing.
2. Internal Parts Upgrades
Replacing internal parts, such as the firing pin, firing pin safety, or connector, may improve reliability and trigger feel. Again, this is best left to experienced gunsmiths.
Conclusion: Choosing the Right Upgrades for Your Glock 20 Gen 4
Choosing the right Glock 20 Gen 4 upgrades depends on your individual needs and shooting style. Prioritize safety and always consult with a qualified gunsmith before undertaking any modifications that involve internal parts or trigger mechanisms. This guide provides a starting point; further research into specific products and reviews will help you make informed decisions. Remember, responsible gun ownership includes safe and informed modifications.
