Choosing between the Glock 21 Gen 5 and Gen 4 can feel overwhelming. Both are reliable workhorses chambered in .45 ACP, but subtle yet significant differences exist. This in-depth comparison will help you decide which generation best suits your needs and shooting style. We'll delve into features, ergonomics, and performance to offer a clear picture for discerning shooters.
Key Differences: Gen 5 vs. Gen 4
The Glock 21 Gen 5 boasts several enhancements over its predecessor, focusing on refined ergonomics and enhanced performance. Here's a breakdown of the crucial differences:
1. Frame and Ergonomics:
- Gen 5: Features an ambidextrous, reversible magazine catch, a smoother frame with a reduced finger grooves design for a more versatile and comfortable grip for a wider range of hand sizes. The front and backstrap texturing provides enhanced grip in various conditions.
- Gen 4: Offers ambidextrous slide stop levers, but the magazine release is only on the left side. It includes interchangeable backstraps, allowing for customization to fit different hand sizes. The finger grooves are more pronounced, potentially affecting comfort for shooters with smaller or larger hands.
Verdict: The Gen 5's improved ergonomics and ambidextrous controls offer a more versatile and user-friendly experience. The Gen 4's interchangeable backstraps remain a useful feature, but the Gen 5's overall design feels more refined and contemporary.
2. Slide and Barrel:
- Gen 5: Features a nDLC (niteride) finish on the slide, enhancing its durability and corrosion resistance. The barrel is also improved with a Marksman barrel, providing enhanced accuracy.
- Gen 4: Employs a tenifer finish on the slide, which is also durable but slightly less resistant to wear than nDLC. The barrel is a standard Glock barrel, still reliable but less refined than the Gen 5 Marksman barrel.
Verdict: The Gen 5's nDLC finish and Marksman barrel offer clear advantages in terms of durability and accuracy.
3. Sights:
- Gen 5: Includes Glock's improved, taller, and more visible sights. These are generally considered an improvement for both speed and accuracy.
- Gen 4: Features standard Glock sights, which, while functional, are not as easily acquired as those on the Gen 5.
Verdict: The Gen 5's sights represent a noticeable improvement in visibility and ease of use.
4. Reliability and Performance:
Both generations are renowned for their reliability. However, the Gen 5's Marksman barrel contributes to slightly improved accuracy. The differences in reliability are minimal, especially for everyday use.
Verdict: Both are reliable, but the Gen 5 edges out in accuracy due to the Marksman barrel.
Which Glock 21 Should You Choose?
The decision ultimately hinges on your individual preferences and priorities:
-
Choose the Glock 21 Gen 5 if: You prioritize enhanced ergonomics, improved durability, superior accuracy, and ambidextrous controls. The modern design and features make it a strong contender.
-
Choose the Glock 21 Gen 4 if: You value the customizable backstraps and find the Gen 5’s design too minimalist, or are on a budget (Gen 4s are often available at lower prices).
Conclusion:
Both the Glock 21 Gen 4 and Gen 5 are excellent handguns. The Gen 5, however, represents a refinement of the platform, offering tangible improvements in ergonomics, durability, and accuracy. While the Gen 4 remains a capable firearm, the Gen 5 is the more modern and advanced option for most shooters. Consider your shooting style, hand size, and budget to make the best decision for your needs.
