Choosing between a Glock 21 Gen 4 and Gen 3 often comes down to personal preference, but understanding the key differences can significantly impact your decision. Both are reliable .45 ACP handguns known for their durability and ease of use, but the Gen 4 boasts several notable upgrades. This in-depth comparison will highlight the key distinctions, helping you determine which generation best suits your needs and shooting style.
Key Differences: Gen 4 vs. Gen 3
The Glock 21 Gen 4 introduces several improvements over its predecessor, primarily focusing on ergonomics, handling, and features. Here's a breakdown of the key differences:
1. Grip Texture and Size
- Gen 4: Features a significantly improved, aggressive, and interchangeable grip texture. This allows for a more secure and comfortable grip, even with wet hands. The backstraps are also interchangeable, allowing you to customize the grip size to perfectly fit your hand. This is a major upgrade for shooters with varying hand sizes.
- Gen 3: Utilizes a smoother, less aggressive grip texture. While reliable, it lacks the adjustability and enhanced grip security offered by the Gen 4's interchangeable backstraps.
2. Magazine Release
- Gen 4: Includes a reversible magazine release, catering to both left-handed and right-handed shooters. This simple yet significant change enhances ambidextrous functionality.
- Gen 3: Features a right-handed magazine release only.
3. Slide Serrations
- Gen 4: Often (though not always) features more aggressive front and rear slide serrations, providing improved grip and manipulation during slide racking.
- Gen 3: Features more subtly defined slide serrations. While functional, they offer less pronounced grip.
4. Internal Upgrades
- Gen 4: Incorporates several internal improvements, including a modified trigger mechanism and improved recoil spring assembly. These often translate to a slightly smoother trigger pull and potentially reduced felt recoil.
- Gen 3: Relies on the previous generation's internal components, which are still highly reliable but may not be as refined as those found in the Gen 4.
5. Weight
- Gen 4: Generally slightly lighter due to material changes and design refinements.
- Gen 3: Slightly heavier. This difference is minimal but noticeable to some shooters.
Which Generation Should You Choose?
The best choice depends on your individual priorities and preferences.
Choose the Glock 21 Gen 4 if:
- Ergonomics are paramount: The adjustable grip and reversible magazine release significantly enhance comfort and usability.
- You prefer a more aggressive grip: The textured grip provides superior control, especially in challenging conditions.
- You want the latest features and refinements: The Gen 4 incorporates several improvements over the Gen 3, including internal component upgrades.
- You're ambidextrous: The reversible magazine release is a significant advantage for left-handed shooters.
Choose the Glock 21 Gen 3 if:

- You prefer a simpler design: The Gen 3’s straightforward design might appeal to some shooters who prefer a less complex firearm.
- You’re already accustomed to a Gen 3 Glock: If you’re familiar with the Gen 3's feel and operation, switching might not be necessary.
