Glock 21 Gen 4: The Workhorse
The Gen 4 Glock 21 solidified Glock's reputation for reliability and performance. Its features were a significant upgrade from previous generations:
Advantages of the Gen 4:
- Interchangeable Backstraps: This allows for a customized grip, enhancing comfort and control for shooters with different hand sizes.
- Reversible Magazine Release: This is a significant advantage for left-handed shooters, who often find themselves forced to adapt to right-handed firearm designs.
- Proven Reliability: The Gen 4 has a long history of reliable performance in diverse conditions, making it a trusted choice for both law enforcement and civilian users.
Disadvantages of the Gen 4:
- Trigger: Compared to the Gen 5, the Gen 4 trigger is heavier and exhibits more perceptible take-up and overtravel. This can slightly impact accuracy and trigger control for some shooters.
- Slightly Heavier: The inclusion of the backstrap system slightly increases the overall weight of the Gen 4.
Glock 21 Gen 5: Refinement and Modernization
The Gen 5 Glock 21 represents refinements and improvements on the established Gen 4 platform. Glock focused on enhancing several key areas:
Advantages of the Gen 5:
- Improved Trigger: The Gen 5 features a significantly improved trigger pull, smoother, lighter and with reduced travel. This leads to improved accuracy and faster shot cycles.
- Enhanced Serrations: The more aggressive slide serrations provide a more secure and positive grip, even with wet or sweaty hands.
- Ambidextrous Features: The ambidextrous slide release and magazine release cater to both right-handed and left-handed shooters without the need for modification or adjustment.
- Lighter Weight: The removal of backstraps results in a slightly lighter pistol, which can be beneficial for extended carry.
- Enhanced Firing Pin Safety: The Gen 5 firing pin safety mechanism is designed to further reduce the chance of accidental discharge.
Disadvantages of the Gen 5:
- Lack of Interchangeable Backstraps: Some shooters appreciate the customizability offered by the Gen 4's interchangeable backstraps; this feature is absent in the Gen 5.
- Potential for Stiffer Grip: The lack of backstraps may result in a less comfortable or less customizable grip for shooters with smaller or larger hands, although many shooters find this is negligible.
The Verdict: Which Glock 21 Should You Choose?
The best choice depends entirely on your individual preferences and shooting style.
- Choose the Glock 21 Gen 4 if: You prioritize the customizable grip offered by interchangeable backstraps and prefer a heavier firearm.
- Choose the Glock 21 Gen 5 if: You value an improved trigger, enhanced slide serrations, ambidextrous controls, and a lighter firearm.
Ultimately, both the Gen 4 and Gen 5 Glock 21 are highly reliable and capable handguns. Consider handling both models before making a final decision to ensure the best fit for your hand and shooting style. Remember to always practice safe gun handling and consult a firearms professional for personalized advice.
