Choosing between the Glock 17 and Glock 20 often comes down to individual needs and preferences. Both are highly reliable and popular handguns, but they cater to different shooting styles and purposes. This detailed comparison will help you understand the key differences to make an informed decision.
Caliber: The Core Distinction
The most significant difference lies in caliber: the Glock 17 is chambered in 9x19mm Parabellum (9mm), while the Glock 20 fires the significantly more powerful .10mm Auto. This difference impacts everything from recoil and stopping power to ammunition cost and availability.
9mm (Glock 17):
- Advantages: Higher magazine capacity, lower recoil, generally less expensive ammunition, more readily available ammunition, easier to control during rapid firing. Better suited for concealed carry due to its lighter weight and smaller size.
- Disadvantages: Lower stopping power compared to .10mm.
.10mm Auto (Glock 20):
- Advantages: Greater stopping power, more effective against larger threats.
- Disadvantages: Higher recoil, lower magazine capacity, more expensive ammunition, can be more difficult to control, especially for novice shooters. Generally bulkier and heavier, less suitable for concealed carry.
Size and Weight: A Matter of Feel
While both are full-size pistols, the Glock 20 is noticeably larger and heavier than the Glock 17 due to its larger cartridge. This difference is significant for concealed carry and extended shooting sessions.
Glock 17:
- Advantages: More compact and lightweight, easier to conceal and carry for extended periods.
- Disadvantages: May feel smaller in the hand for those with larger hands.
Glock 20:
- Advantages: More substantial feel in the hand, can offer better control for some shooters, especially those with larger hands.
- Disadvantages: Bulkier and heavier, less comfortable for concealed carry and extended use.
Recoil and Control: A Significant Factor
The significant difference in caliber directly translates to recoil. The Glock 20's .10mm round produces substantially more recoil than the Glock 17's 9mm.
Glock 17:
- Advantages: Manageable recoil, allowing for faster follow-up shots and better accuracy during rapid fire.
- Disadvantages: Less powerful round.
Glock 20:
- Advantages: The powerful round can offer a decisive advantage in self-defense situations.
- Disadvantages: The stronger recoil can be challenging for novice shooters and may impact accuracy, especially during rapid fire.
Ammunition Cost and Availability: A Practical Consideration
9mm ammunition is far more widely available and significantly cheaper than .10mm Auto. This is a crucial factor to consider for regular range practice and long-term ownership.
Glock 17:
- Advantages: Abundant and affordable ammunition.
- Disadvantages: None in this context.
Glock 20:
- Advantages: None in this context.
- Disadvantages: Limited availability and higher cost of ammunition.
Conclusion: The Best Choice Depends on Your Needs
The "better" gun depends entirely on your priorities. The Glock 17 is the more versatile and practical choice for most users due to its lower recoil, higher capacity, greater ammunition availability, and lower cost. It's an excellent all-around pistol suitable for self-defense, sport shooting, and law enforcement.
The Glock 20 is a powerful handgun, ideal for those prioritizing stopping power above all else. However, its stronger recoil, higher ammunition cost, and bulkier size may make it less suitable for beginners or those seeking a concealed carry option. Consider your experience level, intended use, and budget carefully before making your decision. Always practice safe gun handling and seek professional training.
