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)
  • Crimson Trace Lasergrip (for improved target acquisition)
