Glock 20 Gen 3 Design and Ergonomics
Grip and Frame
The Gen 3 frame features finger grooves and a textured grip, providing better control, especially when handling the powerful 10mm Auto round. The polymer frame keeps the weight manageable while maintaining durability.
Slide and Barrel
The Glock 20 Gen 3 has a Tennifer-coated steel slide, which enhances resistance to corrosion and wear. The 4.6-inch barrel is designed to maximize accuracy while maintaining a compact profile for carry purposes.
Sights and Controls
The factory sights are standard Glock white-dot front and U-notch rear, which can be upgraded with night sights or fiber optics. The magazine release and slide stop lever are positioned for easy access, making reloading quick and efficient.
Performance and Handling
Recoil and Control
The 10mm Auto round generates more recoil than 9mm, but the Glock 20’s polymer frame and ergonomic grip help mitigate it. A heavier slide and strong recoil spring reduce muzzle flip, allowing for quick follow-up shots.
Accuracy and Range
With its 4.6-inch barrel, the Glock 20 Gen 3 provides excellent accuracy at medium to long distances. The 10mm round has a flatter trajectory compared to .45 ACP, making it suitable for both self-defense and hunting applications.
Reliability and Durability
As expected from Glock, the Gen 3 Glock 20 is highly reliable, capable of firing thousands of rounds without failure. The Tennifer finish ensures corrosion resistance, making it ideal for various environments.
Customization and Accessories
Aftermarket Triggers
Upgrading to an aftermarket trigger can improve the Glock 20’s trigger pull, reset, and overall shooting experience. Popular options include:
- Zev Technologies Fulcrum Trigger
- Apex Tactical Action Enhancement Trigger
Sights Upgrade
Many users prefer night sights or fiber optic sights for better visibility. Popular choices include:
- Trijicon HD Night Sights
- Ameriglo Spartan Tactical Sights
Tactical Lights and Lasers
The Glock rail allows for attachments such as:
- Streamlight TLR-1 HL (high-lumen tactical light)
