Choosing between the Glock 20 and Glock 40 often comes down to individual needs and preferences. Both are powerful 10mm handguns, but they cater to different shooting styles and applications. This in-depth comparison will help you determine which Glock best suits your needs.
Caliber and Capacity: The Foundation of Power
Both the Glock 20 and Glock 40 chamber the potent 10mm Auto cartridge. This round delivers significantly more stopping power than the 9mm, making it a popular choice for self-defense and hunting. However, the recoil is noticeably stronger, demanding more practice and control.
- Capacity: The standard Glock 20 magazine typically holds 15 rounds, while the Glock 40 magazine holds 10. Extended magazines are available for both models, increasing capacity.
Size and Weight: A Matter of Handling
The most significant difference lies in their size and weight:
-
Glock 20: This is a full-size handgun, designed for comfortable handling and reliable performance. Its larger grip provides a better purchase for shooters with larger hands. However, its size makes concealed carry more challenging.
-
Glock 40: The Glock 40 is a long-slide version, offering increased sight radius and potentially improved accuracy. Its longer barrel contributes to a slightly higher velocity. However, its overall length makes concealed carry even more difficult than with the G20. It's also noticeably heavier.
Table Summarizing Key Differences:
| Feature | Glock 20 | Glock 40 |
|---|---|---|
| Caliber | 10mm Auto | 10mm Auto |
| Barrel Length | 4.6 inches | 6 inches |
| Overall Length | 7.95 inches | 9.49 inches |
| Weight (unloaded) | Approximately 28 oz | Approximately 31 oz |
| Standard Capacity | 15 rounds | 10 rounds |
| Typical Use | Self-defense, hunting | Competition, hunting |
Intended Use: Concealed Carry vs. Competition
While both are capable of self-defense, their suitability for concealed carry differs greatly.
-
Concealed Carry: The Glock 20, while manageable for some, is generally considered too large and heavy for comfortable everyday concealed carry for many individuals. The Glock 40 is even less suited for concealed carry due to its increased length and weight.
-
Competition: The Glock 40's longer barrel and increased sight radius make it a more attractive option for competitive shooting, where accuracy is paramount. The extra length enhances stability and helps reduce felt recoil during rapid firing. The Glock 20 can also be used in competition, but the Glock 40 offers advantages in precision shooting.
Recoil Management: A Key Consideration
The 10mm round's significant recoil is a factor in both handguns. The heavier Glock 40, despite its longer barrel, may actually have more felt recoil due to its additional weight being concentrated further back from the firing hand. The additional weight and longer barrel does help to manage muzzle rise.
Conclusion: The Right Choice Depends on Your Needs
Ultimately, the best choice between a Glock 20 and Glock 40 hinges on your priorities. If you need a powerful self-defense handgun with a manageable size (relatively speaking for a 10mm), the Glock 20 might be a better fit. However, if you prioritize accuracy and plan to use the handgun for competition shooting, the Glock 40’s extended barrel and sight radius give it an advantage. Consider your intended use, hand size, and comfort level with recoil before making your decision. Remember to always practice safe gun handling and storage techniques.
