The Glock 20 Gen 4, chambered in the potent 10mm Auto cartridge, is a formidable handgun favored by many for its power and reliability. However, like any firearm, there's always room for improvement. This guide delves into popular and effective Glock 20 Gen 4 upgrades, focusing on enhancing accuracy, ergonomics, and overall performance. We'll explore various options, from simple modifications to more significant enhancements, helping you tailor your Glock 20 Gen 4 to your specific needs and shooting style. Remember, always prioritize safety and legality when modifying your firearm.
Enhancing Accuracy: Trigger and Sights
One of the most impactful upgrades for improving accuracy on your Glock 20 Gen 4 is improving the trigger and sights. The factory trigger, while functional, can be somewhat gritty and heavy. Upgrading to an aftermarket trigger can significantly enhance your shooting experience.
Trigger Upgrades
-
Aftermarket Trigger Kits: Numerous companies offer aftermarket trigger kits designed to reduce trigger pull weight, improve the break, and provide a smoother overall feel. Popular options include the Ghost, Apex Tactical, and ZEV Technologies trigger kits. These often involve replacing the trigger bar, connector, and/or springs. Caution: Always ensure your trigger modifications comply with local laws and regulations. Improper installation can render your firearm unsafe.
-
Trigger Job: A professional gunsmith can perform a trigger job, carefully polishing and refining internal trigger components for a lighter, crisper trigger pull. This option often yields excellent results, but requires the expertise of a qualified professional.
Sight Upgrades
Factory Glock sights are functional, but many shooters opt for upgrades for improved visibility and accuracy.
-
Night Sights: Night sights are crucial for low-light shooting. Tritium or fiber optic sights offer enhanced visibility in various lighting conditions. Several manufacturers offer Glock-specific night sights with various designs and color options.
-
Improved Sights: Consider upgrading to higher-quality sights with a more precise design, such as those with a wider rear notch or a more defined front sight post.
Ergonomics and Comfort: Grips and Other Enhancements
Improving the ergonomics of your Glock 20 Gen 4 can significantly enhance comfort and control during extended shooting sessions.
Grip Upgrades
-
Aftermarket Grips: Several companies offer aftermarket grips for the Glock 20 Gen 4, often made from materials like rubber, polymer, or wood. These grips can enhance your grip texture, improve your purchase on the gun, and provide additional comfort. Some grips feature aggressive texturing for improved control during recoil, while others provide a softer feel for better comfort during long shooting sessions.
-
Grip Tape: A simpler and more cost-effective option is applying grip tape to the factory grip. This can provide increased traction and improve grip security without the expense of a full grip replacement.
Other Ergonomic Upgrades
-
Extended Magazine Releases: An extended magazine release can make magazine changes faster and easier, particularly for shooters with larger hands.
-
Slide Stop Lever: An enlarged slide stop lever can make slide operation quicker and simpler.
Enhancing Reliability and Performance: Internal Upgrades
While less visually apparent, internal upgrades can significantly enhance the reliability and performance of your Glock 20 Gen 4.
Internal Parts
-
Recoil Spring Assembly: Upgrading to a heavier recoil spring can help reduce recoil and improve overall felt recoil. This is particularly beneficial when using heavier 10mm loads.
-
Extractor: An upgraded extractor can improve reliability by ensuring consistent and positive cartridge extraction.
