Choosing between the Glock 17 and Glock 20 is a common dilemma for firearm enthusiasts, particularly those considering concealed carry or home defense. Both are highly reliable and popular handguns, but they cater to different needs and preferences. This in-depth comparison will explore the key differences, helping you make an informed decision based on your specific requirements.
Key Differences: Caliber and Capacity
The most significant distinction lies in their caliber: the Glock 17 is chambered in 9x19mm Parabellum (9mm), while the Glock 20 is chambered in 10mm Auto. This fundamental difference impacts several aspects of performance and suitability.
-
Caliber: 9mm is a widely available, relatively inexpensive, and less-recoil cartridge, making it a popular choice for training and everyday carry. 10mm Auto, on the other hand, delivers significantly more stopping power, but with considerably more recoil and a higher cost per round.
-
Capacity: Standard Glock 17 magazines typically hold 17 rounds (hence the model number), while Glock 20 magazines usually hold 15 rounds. Extended magazines are available for both models, further increasing capacity.
Recoil and Shootability
The difference in caliber directly translates to a noticeable difference in recoil.
-
Recoil: The Glock 17's 9mm cartridge offers significantly less recoil, making it easier to control, especially for new shooters or those with smaller builds. The Glock 20's 10mm recoil is substantially more pronounced, requiring more practice to master and potentially making it less suitable for individuals sensitive to recoil.
-
Shootability: While the Glock 17's lower recoil promotes faster follow-up shots and improved accuracy, the Glock 20's greater stopping power compensates for the increased recoil in self-defense situations. Ultimately, "shootability" is subjective and depends heavily on individual shooter experience and preferences.
Size and Weight
While both pistols share a similar design aesthetic, subtle differences in dimensions and weight exist.
-
Size: The Glock 17 is slightly smaller and lighter than the Glock 20, making it more easily concealable for some individuals. However, both are considered full-size handguns, so concealed carry might require proper training and a well-fitting holster.
-
Weight: The weight difference, while not drastic, can impact carry comfort over extended periods. The Glock 17's lighter weight reduces fatigue, whereas the Glock 20's added weight might be perceived as more substantial and stable during shooting.
Ammunition Cost and Availability
A practical consideration for any firearm owner is the cost and availability of ammunition.
-
Ammunition Cost: 9mm ammunition is significantly cheaper and more readily available than 10mm ammunition. This is a crucial factor for those who plan to engage in frequent practice.
-
Ammunition Availability: The widespread popularity of 9mm ensures consistent availability, while 10mm ammo, though increasing in availability, might be harder to find in certain regions or during periods of high demand.
Glock 17 vs. Glock 20: The Verdict
There's no single "winner" in this comparison; the best choice depends entirely on your priorities and intended use.
-
Choose the Glock 17 if: You prioritize lower recoil, easier shootability, lower ammunition costs, greater ammunition availability, and slightly improved concealability. It's an excellent all-around choice for both self-defense and recreational shooting.
-
Choose the Glock 20 if: You require maximum stopping power, aren't overly concerned about recoil, and are willing to pay a premium for ammunition. This pistol is a potent option for situations demanding superior stopping power, such as hunting larger game or serious self-defense scenarios.
Ultimately, the best way to determine which Glock is right for you is to handle both firearms, if possible, and fire them at a range. Consider your experience level, intended use, and personal preferences to make the most informed decision. Always remember to prioritize safety and follow all applicable firearm safety regulations.
