Choosing between the Glock 21 Gen 4 and Gen 3 often boils down to personal preference, but understanding the key differences is crucial for making an informed decision. Both are reliable, hard-hitting .45 ACP pistols, but the Gen 4 boasts several refinements over its predecessor. This in-depth comparison will explore the features, benefits, and drawbacks of each generation, helping you determine which Glock 21 is the right fit for you.
Key Differences: Gen 4 vs. Gen 3
The Glock 21 Gen 4 incorporates several improvements over the Gen 3, focusing on ergonomics, performance, and overall handling. Let's break down the most significant distinctions:
1. Frame: The Enhanced Grip Texture and Interchangeable Backstraps
-
Gen 4: Features a significantly improved grip texture, offering enhanced control and reduced slippage, even in wet or sweaty conditions. The Gen 4 also includes interchangeable backstraps, allowing for customized grip size to fit a wider range of hand sizes. This adjustability significantly improves comfort and shootability.
-
Gen 3: Utilizes a smoother, less aggressive grip texture. While reliable, it offers less aggressive gripping power compared to the Gen 4's textured surface. The lack of interchangeable backstraps limits customization options.
2. Magazine Release: Ambidextrous Design
-
Gen 4: Incorporates an ambidextrous magazine release, catering to both right-handed and left-handed shooters. This is a significant upgrade for users who prefer to operate the magazine release with their non-dominant hand.
-
Gen 3: Features a right-hand-only magazine release. Left-handed shooters must either adapt or seek aftermarket modifications.
3. Recoil Spring Assembly: Dual Recoil Springs
-
Gen 4: Employs a dual recoil spring assembly, contributing to a smoother, more consistent recoil impulse and reduced felt recoil. This also enhances the longevity of the firearm.
-
Gen 3: Uses a single recoil spring. While reliable, it generally exhibits slightly more recoil and may wear faster over time compared to the dual recoil spring system in the Gen 4.
4. Rail System: Accessory Rail for Added Functionality
- Both Gen 3 and Gen 4: Both models include an integral accessory rail, allowing for the attachment of tactical lights, lasers, and other accessories. This enhancement offers significant advantages for law enforcement, competitive shooting, and self-defense applications.
Performance and Reliability: A Close Match
Both the Glock 21 Gen 3 and Gen 4 are renowned for their exceptional reliability and performance. The differences in recoil and handling primarily stem from the features discussed above (grip texture, recoil spring assembly). The Gen 4 generally provides a slightly more comfortable and controllable shooting experience, but both pistols will reliably cycle ammunition under normal conditions.
Choosing the Right Glock 21: Gen 3 or Gen 4?
The decision ultimately comes down to personal preference and priorities:
-
Choose the Gen 4 if: You prioritize enhanced ergonomics, an ambidextrous magazine release, improved grip texture, and a smoother recoil impulse. The customizable backstraps are a significant advantage for shooters with varied hand sizes.
-
Choose the Gen 3 if: Budget is a primary concern (Gen 3s are often more affordable on the used market) and you don't require the features offered by the Gen 4. If you're a right-handed shooter and don't need an ambidextrous magazine release, the Gen 3 remains a solid choice.
Conclusion: Two Excellent Options
Both the Glock 21 Gen 3 and Gen 4 represent excellent choices in the .45 ACP handgun market. The Gen 4 offers noticeable improvements in ergonomics and handling, while the Gen 3 provides a more budget-friendly option with proven reliability. Careful consideration of the differences highlighted in this comparison will allow you to select the Glock 21 that best suits your individual needs and shooting style.
