Choosing between the Glock 45 and Glock 40 often comes down to personal preference and intended use. Both are reliable and powerful handguns, but they have key differences that significantly impact handling, concealability, and overall shooting experience. This in-depth comparison will help you decide which Glock is right for you.
Caliber: The Foundation of the Difference
The most significant difference lies in caliber: the Glock 45 is chambered in 9x19mm Parabellum (9mm), while the Glock 40 is chambered in .40 Smith & Wesson Auto (.40 S&W). This impacts everything from recoil and capacity to ammunition availability and cost.
9mm (Glock 45): Advantages
- Higher Capacity: 9mm magazines generally hold more rounds than .40 S&W magazines, offering a greater capacity for self-defense or competition shooting.
- Lower Recoil: 9mm cartridges produce less recoil than .40 S&W, leading to faster follow-up shots and improved accuracy, especially for less experienced shooters.
- Cost-Effectiveness: 9mm ammunition is typically less expensive than .40 S&W, allowing for more practice at the range.
- Wider Availability: 9mm ammunition is more widely available than .40 S&W, especially in times of high demand.
.40 S&W (Glock 40): Advantages
- Stopping Power: .40 S&W cartridges are generally considered to have greater stopping power than 9mm, although the effectiveness of different calibers is a complex and debated topic.
- FBI's Past Choice: The .40 S&W enjoyed significant popularity with law enforcement agencies, including the FBI, for a considerable time, although many agencies have since transitioned to 9mm.
Size and Weight: Concealability and Handling
Both the Glock 45 and Glock 40 are full-size pistols, but there are subtle differences in their dimensions and weight.
Glock 45: Size and Weight Advantages
- Slightly Smaller Grip: The Glock 45 features a slightly shorter grip than the Glock 40, which can enhance concealability for some users.
- Reduced Overall Weight (Often): While the exact weight can vary slightly depending on the specific model and accessories, the Glock 45 often weighs less than the Glock 40, making it potentially more comfortable to carry for extended periods.
Glock 40: Size and Weight Considerations
- Larger Grip: The Glock 40’s larger grip might be more comfortable for shooters with larger hands.
- Increased Weight (Often): The extra weight can contribute to greater muzzle control, but also to more fatigue during extended shooting sessions or when carrying concealed.
Ergonomics and Handling
Both pistols are known for their ergonomic designs, but the difference in grip size impacts how they feel in the hand.
Glock 45: Ergonomics
- Improved Grip Size (for some): The slightly smaller grip of the Glock 45 can be more comfortable for those with smaller hands, enhancing control and accuracy.
Glock 40: Ergonomics
- Larger Grip (for some): The larger grip of the Glock 40 can be more comfortable and offer better control for those with larger hands. However, this can also make it less easy to conceal.
Which Glock Should You Choose?
The best choice depends on your priorities:
-
Concealed Carry Focused: The Glock 45’s smaller size and often lighter weight might make it a more comfortable choice for concealed carry, especially for those with smaller hands. The lower recoil of the 9mm is also beneficial for quicker follow-up shots in a self-defense situation.
-
Stopping Power Prioritized (Debated): If stopping power is your absolute top priority (though the effectiveness of different calibers is a complex subject), the Glock 40 in .40 S&W might be the preferred choice. However, the higher recoil and potentially lower capacity should be considered.
-
Competition Shooting: The higher capacity and lower recoil of the Glock 45 make it more suitable for competition shooting, allowing for faster and more accurate target engagement.
Ultimately, renting or borrowing both models to test them at a shooting range is highly recommended before making a final purchasing decision. This allows you to experience the differences firsthand and determine which pistol best suits your individual needs and shooting style.
