Choosing between the Glock 20 and the Glock 17 can be a tough decision for handgun enthusiasts. Both are incredibly popular and reliable pistols, but they cater to different needs and preferences. This in-depth comparison will analyze key features, performance, and applications to help you make an informed choice. We'll explore the Glock 20 vs 17 debate point-by-point.
Caliber and Stopping Power: The Core Difference
The most significant difference between the Glock 20 and the Glock 17 lies in their caliber. The Glock 17 is a 9x19mm Parabellum (9mm) pistol, while the Glock 20 fires the significantly more powerful 10mm Auto cartridge. This caliber difference drastically impacts their stopping power and recoil characteristics.
-
Stopping Power: The 10mm Auto round delivers substantially more energy and stopping power than the 9mm. This makes the Glock 20 a more effective choice for hunting larger game or situations demanding immediate incapacitation. However, this power comes at a cost, as explained below.
-
Recoil: The increased power of the 10mm results in noticeably stronger recoil than the 9mm. This makes the Glock 20 more challenging to control, especially for shooters with less experience. The Glock 17's lighter recoil allows for faster follow-up shots and greater accuracy in rapid fire.
| Feature | Glock 17 (9mm) | Glock 20 (10mm) |
|---|---|---|
| Caliber | 9x19mm Parabellum | 10mm Auto |
| Stopping Power | Moderate | High |
| Recoil | Low | High |
| Capacity | 17 rounds (standard) | 15 rounds (standard) |
| Size & Weight | Smaller, Lighter | Larger, Heavier |
Size, Weight, and Concealed Carry
The difference in caliber directly impacts the size and weight of each pistol.
-
Glock 17: Its smaller size and lighter weight make it a more suitable option for concealed carry, particularly for individuals with smaller builds. Many prefer the Glock 17 for everyday carry (EDC) due to its manageability and ease of concealment.
-
Glock 20: The larger frame and heavier weight of the Glock 20 make it less ideal for concealed carry. While not impossible to conceal, it’s more challenging and may be less comfortable for extended periods. This makes it a better choice for open carry or home defense.
Practical Applications: Home Defense vs. Everyday Carry
The choice between the Glock 20 and the Glock 17 greatly depends on your intended use.
-
Home Defense: The Glock 20's superior stopping power makes it a compelling option for home defense. The 10mm round offers increased effectiveness in stopping threats, potentially reducing the number of shots required. However, the stronger recoil needs to be considered.
-
Everyday Carry (EDC): The Glock 17’s lighter weight, smaller size, and manageable recoil make it a more popular choice for EDC. Its greater magazine capacity also offers an advantage in self-defense situations.
-
Hunting: The Glock 20 is frequently used for hunting smaller game, given its greater stopping power compared to a 9mm. However, specialized hunting rifles or shotguns are usually preferred for most hunting situations.
Ergonomics and Handling
Both pistols are known for their ergonomic designs. However, the Glock 20’s larger size might feel more substantial and comfortable in larger hands, while the Glock 17 fits smaller hands better. The Glock 20’s increased recoil can be a factor for shooters with less experience.
Ammunition Availability and Cost
The 9mm ammunition for the Glock 17 is significantly more widely available and generally less expensive than 10mm ammunition for the Glock 20. This is a critical consideration for frequent range practice and long-term ownership.
Conclusion: Which Glock is Right for You?
The “better” Glock—the 20 or the 17—depends entirely on your individual needs and priorities. There is no single right answer.
-
Choose the Glock 17 if: You prioritize concealability, lower recoil, ease of handling, lower ammunition costs, and wider ammunition availability. It’s a versatile choice for concealed carry, self-defense, and range practice.
-
Choose the Glock 20 if: You need maximum stopping power, are less concerned about concealability, and are willing to manage stronger recoil. It's a better fit for home defense and situations requiring superior stopping power.
Ultimately, the best way to decide is to handle both pistols, if possible, and consider your specific requirements. Careful consideration of these factors will lead you to the Glock that best meets your needs.
