Glock 34 vs. Glock 17: Key Differences
While both pistols share Glock’s signature polymer frame, striker-fired mechanism, and reliability, they have distinct differences that impact performance, handling, and intended use.
Barrel Length & Accuracy:
One of the most notable differences between the Glock 34 and Glock 17 is barrel length:
- Glock 34: 5.31 inches
- Glock 17: 4.49 inches
Longer barrel increases muzzle velocity, which can slightly enhance accuracy and reduce bullet drop over distance. This makes the Glock 34 more suitable for precision shooting and competitions, where tight shot groupings matter. However, the Glock 17’s shorter barrel allows for easier concealment and faster draw speed, making it a preferred choice for self-defense and duty use.
Sight Radius & Precision:
With a longer slide and barrel, the Glock 34 naturally has an extended sight radius compared to the Glock 17. This means:
- More precise aiming
- Reduced sight misalignment errors
- Better accuracy at longer distances
However, for close-quarters combat or self-defense scenarios, the Glock 17 is more practical due to its compact size and faster target acquisition.
Intended Use: Competition vs. Tactical Applications
The Glock 34 was specifically designed for competition shooting and comes with an extended slide release and a lighter trigger pull (in some models) for faster, more controlled shots. The Glock 17, on the other hand, is built for law enforcement, military, and self-defense. Its balanced size and capacity make it a versatile all-around firearm, suitable for both open and concealed carry.
Weight & Balance:
The Glock 34’s longer slide and barrel increase overall weight and shift the balance forward. This can help reduce muzzle flip, making it easier to keep sights on target during rapid fire.
However, some shooters prefer the more balanced feel of the Glock 17, which is easier to maneuver, especially in dynamic shooting environments.
Can You Use a Glock 34 Barrel in a Glock 17?
Yes, a Glock 34 barrel technically fits into a Glock 17 slide, but with some important considerations:
1. Protrusion from the Slide:
Since the Glock 34 barrel is 0.82 inches longer than the Glock 17 slide, it will extend beyond the slide’s front cut. This may not be an issue in casual shooting but could present a problem in holster fitment and tactical applications.
2. Performance Considerations:
A longer barrel may slightly improve velocity, but the gains are minimal. The extended barrel could also disrupt the pistol’s balance, making it front-heavy.
3. Legal & Functional Issues:
In some jurisdictions, modifying a firearm’s barrel length could have legal implications. Always check local laws before making modifications.
Can You Use a Glock 34 Slide on a Glock 17 Frame?
Yes, the Glock 34 slide can be mounted onto a Glock 17 frame because both models share a similar frame size and rail system. However, there are some pros and cons to consider.
Advantages of using Glock 34 Slide:
- Improved Accuracy: The longer sight radius enhances precision.
- Better Competition Performance: The longer slide allows smoother tracking during rapid fire.
- Compatible Frame: The Glock 17 frame is functionally identical to the Glock 34 frame, so the fit is seamless.
Disadvantages of using Glock 34 Slide:
- Added Weight: The longer slide makes the gun front-heavy, affecting handling.
- Holster Fitment Issues: Standard Glock 17 holsters may not accommodate the Glock 34 slide.
- Potential Reliability Differences: Some users report slight changes in recoil impulse, which could affect performance in high-stress situations.
While this modification is possible, it’s generally recommended only for competition shooting, where weight and concealability are less of a concern.
FAQs:
1. What is the main difference between a Glock 17 and Glock 34?
The Glock 34 has a longer barrel (5.31 inches) and slide, making it better suited for competition shooting. The Glock 17 has a shorter barrel (4.49 inches) and is designed for self-defense and duty use.
2. Is the Glock 34 better for competition shooting?
Yes. Its longer barrel, extended sight radius, and competition-friendly trigger make it a top choice for precision shooting sports.
3. Can you carry a Glock 34 for self-defense?
Yes, but the longer slide and barrel make it harder to conceal compared to the Glock 17 or Glock 19.
4. Can you put a Glock 34 barrel in a Glock 17?
Yes, but the barrel will protrude from the slide, which may cause holster and balance issues.
5. Can a Glock 34 slide fit a Glock 17 frame?
Yes, but it adds weight and changes the pistol’s balance. This setup is better for competition shooting than tactical applications.
6. Which gun is more accurate: Glock 34 or Glock 17?
The Glock 34 has a longer sight radius and barrel, making it inherently more accurate in skilled hands. However, for practical shooting, both are equally reliable.
Final Thoughts: Which One Should You Choose?
Both the Glock 34 and Glock 17 are outstanding 9mm pistols, but they serve different purposes:
- Choose the Glock 34: If you want maximum accuracy, competition-ready features, and a longer sight radius.
- Choose the Glock 17: If you need a reliable, versatile firearm for self-defense, law enforcement, or everyday carry.
Ultimately, your shooting goals and preferences should guide your decision. Try both models and see which feels better in your hands before making a purchase.
