Best Glock 20 Upgrades for Accuracy & Reliability

The Glock 20, chambered in the powerful 10mm Auto, is a formidable handgun known for its reliability and stopping power. However, like any firearm, there's always room for improvement. This guide explores the best Glock 20 upgrades focused on enhancing both accuracy and reliability, transforming your pistol into a precision instrument.

Enhancing Accuracy: Upgrades for Precision Shooting

Accuracy in a handgun boils down to several factors: trigger control, sight picture, and the gun's inherent mechanical precision. Upgrades can significantly improve each of these areas.

1. Upgraded Trigger: The Heart of Accuracy

The stock Glock trigger, while reliable, is often criticized for its long and somewhat gritty pull. Upgrading the trigger is one of the most impactful changes you can make for improved accuracy. Consider these options:

• Aftermarket Trigger Kits: Many reputable manufacturers offer complete trigger kits that replace the trigger, connector, and trigger bar. These kits often feature a lighter, smoother pull, reducing trigger creep and overtravel. Look for kits specifically designed for the Glock 20. Always ensure any modifications comply with your local laws and regulations.

• Trigger Connectors: Replacing just the connector can significantly improve the trigger feel. Lighter connectors reduce the trigger pull weight, but be mindful of dropping the weight too much, as this can compromise safety.

• Trigger Shoes: These are simply replacement trigger faces, offering different textures and shapes for improved grip and control.

2. Enhanced Sights: Clarity is Key

Factory Glock sights, while functional, are often not ideal for precision shooting. Upgrading to higher-quality sights can drastically improve your sight picture and accuracy:

• Night Sights: Essential for low-light situations, night sights provide a clear sight picture even in darkness. Tritium or fiber optic inserts are common choices.

• Fiber Optic Sights: Excellent for daylight shooting, fiber optic sights offer bright, contrasting sight points that are easily acquired.

• Adjustable Sights: Allow for precise windage and elevation adjustments, ensuring perfect zero at your preferred distance.

3. Barrel Upgrades: Precision Manufacturing

While the factory Glock barrel is reliable, a high-quality aftermarket barrel can often improve accuracy due to superior machining and tighter tolerances:

• Match-Grade Barrels: These barrels are manufactured to tighter tolerances than factory barrels, resulting in increased accuracy. They often feature improved rifling and smoother finishes.

• Threaded Barrels: Allow for the attachment of suppressors or compensators, enhancing both accuracy and sound reduction (with a suppressor). Check your local regulations before installing a threaded barrel.

Boosting Reliability: Upgrades for Dependable Performance

Reliability is paramount in any firearm, especially one intended for self-defense or serious use. These upgrades focus on improving the Glock 20's overall dependability:

1. Extended Magazine Release: Faster Reloads

An extended magazine release allows for quicker and more efficient magazine changes under pressure. This isn't directly related to accuracy, but faster reloads mean you can stay in the fight longer.

2. Enhanced Slide Stop Lever: Positive Engagement

A larger or extended slide stop lever provides more surface area for manipulation, leading to more reliable slide locking during empty magazine situations.

3. Upgraded Extractor: Secure Case Extraction

While rare, extractor failures can occur. A high-quality aftermarket extractor will ensure consistent and reliable case extraction, improving overall reliability.

4. Spring Upgrades: Smoother Cycling

Upgrading recoil and magazine springs to higher-quality components can improve the firearm's cycling reliability, especially with heavier ammunition or modifications.

Conclusion: A More Accurate and Reliable Glock 20

By incorporating these upgrades, you can significantly improve the accuracy and reliability of your Glock 20. Remember to research and choose high-quality parts from reputable manufacturers. Always prioritize safety and ensure all modifications are performed correctly and comply with applicable laws and regulations. Proper installation is crucial for both functionality and safety. Consider professional gunsmithing services if you lack experience with firearm modifications. With careful consideration and the right upgrades, you'll transform your Glock 20 into a more precise and dependable tool.
