Glock 20 Gen 3 Review: The 10mm Beast Built for Power & Performance

Meet the Glock 20 Gen 3: The 10mm Powerhouse

When it comes to power, reliability, and versatility, few handguns compare to the Glock 20 Gen 3. Chambered in the high-performing 10mm Auto, this pistol is trusted by hunters, outdoorsmen, and self-defense professionals who need a firearm that can deliver under extreme conditions.


Why the Glock 20 Gen 3 Stands Out

Here’s what makes this firearm a true standout in the Glock lineup:

🔫 1. Chambered in 10mm Auto

Unlike standard 9mm Glocks, the G20 Gen 3 fires the hard-hitting 10mm round, offering significantly more stopping power and penetration. It’s ideal for hunting, bear defense, and high-stress tactical use.

🧱 2. Rugged, Proven Design

The Gen 3 frame features finger grooves, an accessory rail, and Glock’s signature Safe Action® System. The durable polymer build is lightweight yet resilient, handling recoil and harsh environments with ease.

📏 3. High Capacity & Manageable Recoil

With a 15+1 capacity, the G20 Gen 3 holds more rounds than most 10mm handguns. Glock’s recoil system and ergonomic grip make shooting manageable even with this powerful cartridge.

🔧 4. Upgrade-Friendly Platform

Being a Gen 3 Glock means there’s a huge aftermarket of parts, including triggers, barrels, optics mounts, and holsters. Whether you’re customizing for EDC or backcountry carry, you’ve got options.

  • Firearms enthusiasts who love powerful handguns
  • Collectors who appreciate the legacy of the Gen 3 platform
  • Self-defense users who want serious stopping power

Glock 20 Gen 3 vs. Gen 4 and Gen 5

  • Simplicity & Compatibility: The Gen 3 has a massive aftermarket and a simpler design, making it easier to upgrade or repair.
  • Proven Reliability: Many users prefer Gen 3’s track record for durability and minimal issues.
  • Legal Availability: In some states (like California), the Gen 3 is the only approved version of the G20.
