Glock 19 extended barrels are a popular modification among Glock 19 owners, offering several potential benefits. This guide dives deep into the reasons why shooters choose extended barrels, the types available, and what to consider before making a purchase. Understanding the nuances of Glock 19 extended barrels is crucial for making an informed decision that enhances your shooting experience, rather than hindering it.
Why Choose a Glock 19 Extended Barrel?
The primary reasons for installing a Glock 19 extended barrel often center around improved accuracy and enhanced performance. However, it's vital to understand the trade-offs involved.
Enhanced Accuracy Potential
Longer barrels allow for more complete powder burn. This means the projectile has more time to accelerate before leaving the barrel, potentially resulting in increased velocity and improved accuracy. The longer sight radius also contributes to better precision, especially at longer ranges.
Note: While an extended barrel can improve accuracy, it's not a guaranteed upgrade. The shooter's skill and ammunition quality remain paramount factors affecting accuracy. A poorly-made barrel or inconsistent ammunition can negate any potential benefits.
Increased Velocity
As mentioned, the longer barrel provides more time for the propellant to burn, translating to higher muzzle velocity. This increase in velocity, while sometimes modest, can lead to flatter trajectories and improved downrange performance, particularly noticeable at longer ranges. This increased velocity can make a difference in self-defense situations or competitive shooting.
Compensator Compatibility
Many extended barrels are threaded to accept compensators or flash suppressors. These attachments can reduce recoil and muzzle rise, improving control and follow-up shots. This is particularly advantageous for users who find the Glock 19's recoil a bit snappy.
Types of Glock 19 Extended Barrels
The market offers various Glock 19 extended barrels, each with its own characteristics and intended use:
Threaded Barrels
These barrels feature threads at the muzzle, allowing the attachment of compensators, flash hiders, or sound suppressors. The thread pitch is crucial; ensure compatibility with your chosen accessory. Popular thread pitches include 1/2x28 and 9mmx1/2.
Non-Threaded Barrels
These are standard extended barrels without threads. They offer the benefits of increased velocity and accuracy without the addition of muzzle devices. They are a simpler, less expensive option if you don't need a threaded barrel.
Materials
Glock 19 extended barrels are typically made from stainless steel or carbon steel. Stainless steel barrels are known for their durability and resistance to corrosion. Carbon steel barrels are often lighter but might require more maintenance to prevent rust.
Length Variations
The length of extended barrels varies; some add only a fraction of an inch, while others extend significantly. A longer barrel generally provides greater velocity gains, but it might also increase the overall length of the firearm.
Considerations Before Purchasing
Choosing the right extended barrel involves more than just picking the longest one.
- Legality: Check local and state laws regarding barrel length and modifications. Some jurisdictions have restrictions on firearm modifications.
- Reliability: Ensure the barrel is manufactured by a reputable company known for producing high-quality, reliable parts. Cheap barrels can lead to malfunctions.
- Fit and Finish: Before installing, inspect the barrel for any imperfections. A poorly-made barrel can cause accuracy issues or even damage your firearm.
- Accuracy Testing: After installation, thoroughly test the accuracy of your firearm with the new barrel. This is essential to confirm the improvement (or lack thereof).
- Concealability: Extended barrels obviously increase the overall length of the gun. Consider how this might affect concealability if you intend to carry the weapon concealed.
Case Study: Comparing Accuracy with Standard and Extended Barrels
A recent independent test compared the accuracy of a Glock 19 with a standard barrel and a reputable extended barrel. The results showed a marginal improvement in accuracy with the extended barrel at distances beyond 15 yards. However, at closer ranges, the difference was negligible. This highlights the point that barrel length is not the only factor affecting accuracy.
Conclusion
Glock 19 extended barrels can offer potential improvements in accuracy and velocity, along with the option of adding muzzle devices. However, it's crucial to carefully consider the factors outlined above before making a purchase. Remember that a high-quality barrel from a reputable manufacturer, coupled with proper ammunition and marksmanship, will yield the best results. The extended barrel is a potential enhancement, not a guaranteed one. Don't expect miracles; instead, focus on consistent practice and quality components.
