The Glock 21, a full-size .45 ACP pistol known for its reliability and stopping power, can benefit significantly from a trigger upgrade. Whether you're a seasoned competitor, a dedicated self-defense enthusiast, or simply seeking a more refined shooting experience, improving the trigger pull can dramatically enhance your accuracy and overall enjoyment. This comprehensive guide explores various Glock 21 trigger upgrade options, considerations, and installation advice.
Understanding the Factory Glock 21 Trigger
Before diving into upgrades, it's crucial to understand the factory Glock trigger. Glocks are renowned for their ruggedness and simplicity, but the factory trigger is often described as having a long, heavy pull with considerable take-up and a somewhat gritty feel. This design prioritizes safety and reliability, but it's not ideal for precision shooting or competition. A longer, heavier trigger pull can lead to less precise shot placement, especially under stress.
Popular Glock 21 Trigger Upgrade Options
Several aftermarket companies offer Glock 21 trigger upgrade components designed to improve the trigger pull characteristics. These upgrades often focus on reducing the pull weight, shortening the reset, and smoothing out the overall feel. Here are some of the most popular options:
1. Drop-in Trigger Kits:
These kits typically replace the entire trigger mechanism, offering a relatively straightforward upgrade path. Popular brands include:
-
Apex Tactical Specialties: Known for their high-quality components and precision engineering, Apex offers several trigger kits for the Glock 21, each designed to provide a different level of customization. They frequently focus on reducing the overall weight and improving the break.
-
Ghost Inc.: Ghost Inc. offers a range of trigger components and complete kits. They tend to emphasize a lighter, smoother pull and a shorter reset.
-
ZEV Technologies: ZEV Technologies produces high-end trigger kits and individual components for Glock pistols. Their offerings often feature enhanced materials and precision machining.
Choosing a drop-in kit simplifies the installation process, minimizing the need for specialized tools or gunsmithing experience.
2. Individual Trigger Components:
For more experienced users, upgrading individual components, such as the trigger bar, connector, and springs, allows for finer tuning and customization. This approach allows for a more tailored trigger feel, potentially offering a more precise fit to the shooter's preferences. However, this method requires a deeper understanding of Glock trigger mechanics.
3. Trigger Connectors:
Replacing the connector is often one of the simplest and most effective Glock 21 trigger upgrades. This relatively inexpensive part influences the trigger's pull weight and reset. Experimenting with different connector weights allows for fine-tuning to suit individual preferences and shooting styles.
Considerations Before Upgrading Your Glock 21 Trigger
Before you begin any Glock 21 trigger upgrade, several critical considerations are essential:
-
Legality: Check your local and state laws regarding modified firearms. Some jurisdictions may have restrictions on trigger modifications.
-
Safety: Always prioritize safety. Disassembling and reassembling firearms requires careful attention to detail. If you lack experience, seek the assistance of a qualified gunsmith.
-
Warranty: Modifying your Glock 21 may void the manufacturer's warranty.
-
Functionality: While improvements are common, ensure the trigger functions correctly and reliably after the upgrade. Improper installation can lead to malfunctions.
Installation and Maintenance
Installing a Glock 21 trigger upgrade can vary depending on the specific components. Some upgrades are relatively simple drop-in replacements, while others may require more involved disassembly and reassembly. Always refer to the manufacturer's instructions for specific guidance. Detailed instructions and video tutorials are often available online for many popular Glock trigger upgrade kits. Proper lubrication is crucial for maintaining the smooth operation and longevity of the upgraded trigger.
Conclusion
Upgrading your Glock 21 trigger can significantly improve its performance and your shooting experience. By carefully considering your needs, selecting appropriate components, and following safe installation practices, you can transform your Glock 21 into a more accurate and enjoyable firearm to shoot. Remember always to prioritize safety and legal compliance throughout the process. For those lacking experience, consulting a qualified gunsmith is always recommended.
