Common Glock 19 Gen 5 Problems and How to Fix Them

The Glock 19 Gen 5 is one of the most popular handguns on the market today. Known for its reliability, durability, and versatility, it has become a favorite among law enforcement, military personnel, and civilian gun owners alike. However, like any firearm, the Glock 19 Gen 5 is not without its issues. In this blog post, we’ll discuss some of the most common problems associated with this model and how to address them.

1. Barrel Accuracy Issues

The Problem:

One of the major changes in the Glock 19 Gen 5 is the Marksman Barrel (GMB), which is supposed to improve accuracy. However, some users have reported inconsistent shot groupings.

The Fix:

• Ensure that your grip and stance are consistent.
• Use high-quality ammunition.
• Clean the barrel regularly to remove debris buildup.
• If the issue persists, consider upgrading to an aftermarket barrel.

2. Slide Finish Wear

The Problem:

Glock introduced a new nDLC (Diamond-Like Carbon) finish in the Gen 5 models. While this finish is designed to enhance durability and corrosion resistance, many users have reported excessive wear, particularly around the slide.

The Fix:

• Regularly lubricate the slide to reduce friction.
• Avoid excessive holster use with rough materials that may contribute to wear.
• If aesthetics are a major concern, consider a cerakote or aftermarket refinishing.

3. Ejection Pattern Issues

The Problem:

Some Glock 19 Gen 5 users have experienced erratic ejection patterns, including spent casings hitting the shooter in the face.

The Fix:

• Ensure that you’re using high-quality, factory-loaded ammunition.
• Check and replace the extractor or ejector if it appears worn.
• Upgrade to a stronger recoil spring assembly if necessary.

4. Trigger Complaints

The Problem:

While the Gen 5 trigger is an improvement over previous generations, some users find it too soft or mushy, affecting their shooting experience.

The Fix:

• Break in the trigger with dry fire practice.
• Consider installing an aftermarket trigger for a crisper pull.
• Add a performance connector to reduce trigger pull weight.

5. Magazine Compatibility Issues

The Problem:

The Glock 19 Gen 5 introduced a flared magwell for easier reloads, but this has caused compatibility issues with some aftermarket baseplates and older Glock magazines.

The Fix:

• Use OEM Glock Gen 5 magazines for the best compatibility.
• If using aftermarket extensions, ensure they are Gen 5 compatible.
• Modify the magwell slightly if necessary.

6. Slide Bite for Larger Hands

The Problem:

Some shooters with larger hands experience slide bite due to the design of the grip and beavertail.

The Fix:

• Use a grip sleeve or add an aftermarket beavertail.
• Adjust your grip slightly to avoid the slide’s movement path.

Final Thoughts

Despite these minor issues, the Glock 19 Gen 5 remains a top-tier handgun. Most of these problems have simple fixes, and with regular maintenance and practice, you can optimize its performance. If you’re experiencing persistent issues, consider reaching out to Glock customer support or a professional gunsmith.
