Choosing between the Glock 20 and the Glock 17 often comes down to personal preference and intended use. Both are highly reliable and popular handguns, but they cater to different needs. This detailed comparison will help you decide which Glock is the better fit for you.
Caliber: The Defining Difference
The most significant difference between the Glock 20 and the Glock 17 lies in their caliber. The Glock 17 is chambered in 9x19mm Parabellum (9mm Luger), while the Glock 20 is chambered in 10mm Auto. This fundamental distinction impacts nearly every aspect of their performance and suitability for various applications.
9mm (Glock 17): Advantages
- Higher Capacity: 9mm magazines generally hold more rounds than 10mm magazines, offering a greater capacity for self-defense or competition.
- Lower Recoil: 9mm boasts significantly less recoil than 10mm, making it easier to control, especially for less experienced shooters. This translates to faster follow-up shots and improved accuracy.
- Cost-Effectiveness: 9mm ammunition is considerably cheaper and more widely available than 10mm, a crucial factor for regular practice and training.
- Less Felt Recoil: The reduced recoil makes the 9mm Glock 17 more suitable for smaller framed shooters or those new to firearms.
10mm (Glock 20): Advantages
- Greater Stopping Power: The 10mm round delivers substantially more energy and stopping power than 9mm, making it a favored choice for hunting or situations requiring immediate incapacitation.
- Superior Penetration: 10mm cartridges penetrate barriers more effectively than 9mm rounds, a consideration for self-defense scenarios involving potential threats behind cover.
- Improved Range: The higher velocity of 10mm allows for a flatter trajectory at longer ranges.
Beyond Caliber: Other Key Differences
While caliber is the primary differentiator, other subtle differences exist:
Size and Weight
Both pistols are full-size, but the Glock 20 is slightly larger and heavier due to the larger 10mm cartridge. This added weight can help mitigate recoil but may be less comfortable for concealed carry.
Ergonomics and Feel
The ergonomic design of both pistols is largely similar, but the added size and weight of the Glock 20 might feel different in the hand. It's crucial to handle both before making a decision to determine personal preference.
Magazine Capacity
As mentioned, the Glock 17 typically offers higher magazine capacity due to the smaller 9mm cartridge. However, extended magazines are available for both models.
Which Glock is Right for You?
The best Glock depends entirely on your needs:
- Glock 17 (9mm): Ideal for self-defense, target shooting, concealed carry (with appropriate holster), law enforcement, and competitive shooting. It's a versatile and cost-effective option.
- Glock 20 (10mm): Better suited for hunting, situations demanding superior stopping power, and those who prioritize raw power over capacity and recoil management.
Ultimately, renting or handling both models at a range is highly recommended before making a purchase. This allows you to experience the recoil, ergonomics, and overall feel of each pistol firsthand, leading to a more informed decision. Remember to prioritize safety and always follow proper firearm handling procedures.
