Choosing between the Glock 21 Gen 4 and Gen 5 can feel overwhelming. Both are reliable, full-sized .45 ACP pistols, popular for self-defense and target shooting. This in-depth comparison will highlight the key differences to help you decide which Glock 21 generation best suits your needs. We'll cover everything from ergonomics and features to performance and reliability, ensuring you're well-informed before making your purchase.
Key Differences Between Glock 21 Gen 4 and Gen 5
The Glock 21 Gen 5 boasts several improvements over its predecessor. While the Gen 4 offered significant advancements over earlier generations, the Gen 5 refines the design even further. Let's delve into the specifics:
Ergonomics and Grip Texture
-
Gen 4: Features interchangeable backstraps allowing for customization of the grip. This allows shooters with different hand sizes to achieve a more comfortable and secure grip. The Gen 4 also utilizes a rough, stippled grip texture.
-
Gen 5: Removes the interchangeable backstraps, opting for a more aggressive, unified texturing across the entire grip. This provides enhanced control and reduces the chance of slippage, especially during rapid firing or in adverse conditions. The absence of backstraps streamlines the design and reduces overall weight.
Slide Design and Features
-
Gen 4: Retains the traditional Glock slide serrations, which are effective but can sometimes be less aggressive than newer designs.
-
Gen 5: Introduces ambidextrous slide serrations, providing improved control during slide manipulation for both right- and left-handed shooters. This is a significant upgrade for many users, especially those who might need to manipulate the slide under duress. The Gen 5 also features a nDLC (Nitrocarburized Diamond-Like Carbon) finish on the slide, enhancing corrosion resistance and durability.
Trigger and Trigger Mechanism
-
Gen 4: Uses a slightly heavier trigger pull than the Gen 5. While still consistent with Glock's known reliability, some users might prefer the slightly lighter pull of the Gen 5.
-
Gen 5: Features a slightly improved, lighter trigger pull, resulting in a crisper, more responsive shooting experience. This enhancement, combined with the improved grip, can lead to improved accuracy and quicker target acquisition.
Barrel and Performance
-
Gen 4: Uses a standard Glock barrel, known for reliability and accuracy.
-
Gen 5: Incorporates a Marksman barrel design, which features improvements to rifling that contributes to increased accuracy. While the difference might not be immediately noticeable to all shooters, precision-oriented users may appreciate the enhancement.
