Choosing between the Glock 17 and Glock 20 often comes down to a single, critical factor: caliber. Both are highly regarded, full-size Glock pistols, but they cater to different needs and preferences. This in-depth comparison will help you determine which pistol best suits your requirements.
Caliber: The Key Difference
The most significant distinction between the Glock 17 and Glock 20 lies in their caliber:
- Glock 17: 9x19mm Parabellum (9mm Luger)
- Glock 20: 10mm Auto
This difference impacts several aspects, including recoil, stopping power, ammunition availability, and cost.
9mm vs. 10mm: A Detailed Look
The 9mm is a widely popular, readily available, and relatively inexpensive cartridge. It offers manageable recoil, making it suitable for beginners and experienced shooters alike. Its smaller size allows for higher magazine capacity, giving you more rounds per magazine.
The 10mm Auto, on the other hand, delivers significantly more stopping power. Its larger projectile and higher velocity create a substantial impact on target. However, this power comes at a price: recoil is considerably stronger, and ammunition is generally more expensive and sometimes harder to find than 9mm.
Beyond Caliber: Other Key Considerations
While caliber is the primary differentiator, other factors should also influence your decision:
Recoil and Shootability:
- Glock 17 (9mm): Offers noticeably less recoil, making it easier to control and shoot accurately, especially for extended periods or for those new to firearms. Rapid follow-up shots are simpler.
- Glock 20 (10mm): Packs a powerful punch, resulting in more significant recoil. This can be challenging for novice shooters or those with less upper body strength. While manageable with practice, it demands more control and technique.
Capacity:
- Glock 17 (9mm): Typically holds 17 rounds in standard magazines, with higher-capacity magazines available.
- Glock 20 (10mm): Standard magazines generally hold 15 rounds, with slightly lower capacity options available compared to the 9mm.
Cost:
- Glock 17 (9mm): Generally less expensive in terms of both the firearm itself and the ammunition.
- Glock 20 (10mm): Usually more expensive to purchase, and the ammunition cost is significantly higher per round.
Intended Use:
Consider your intended purpose for the firearm. The Glock 17's 9mm is a versatile round suitable for self-defense, target shooting, and competitive shooting. The Glock 20's 10mm is better suited for situations requiring greater stopping power, such as hunting larger game (with appropriate ammunition) or personal defense against larger threats. However, this requires rigorous practice to master the recoil and maintain accuracy.
Which Glock is Right for You?
The best choice depends entirely on your individual needs and priorities.
-
Choose the Glock 17 (9mm) if: You prioritize lower recoil, greater capacity, lower cost of ammunition, and ease of handling. This is a fantastic all-around pistol suitable for a wide range of applications.
-
Choose the Glock 20 (10mm) if: You require greater stopping power and are comfortable managing stronger recoil. You are willing to pay a premium for ammunition and prioritize stopping power above all else. This is a powerful pistol suitable for those who demand maximum impact.
Ultimately, the best way to decide is to handle both pistols if possible and consider your specific needs and shooting experience. Consider renting both at a range before making your purchase. Remember, safety should always be your top priority when handling firearms.
