Glock 27 Gen 4 Problems

Glock 27 Gen 4 Problems

The Glock 27 Gen 4 is a reliable firearm with a solid reputation. However, some users have reported experiencing issues with the recoil spring assembly and slide stop lever.

More, due to its compact size, it might be challenging for those with larger hands to maintain a comfortable grip, potentially affecting accuracy.

As with any firearm, regular maintenance and proper handling are essential to prevent these issues and ensure optimal performance.

1. Excessive Recoil


The excessive recoil of the Glock 27 Gen 4 is often attributed to its lightweight and compact design, which includes a shorter barrel and grip. 

The physics of shooting a high-powered round from such a small firearm tends to generate more recoil felt by the shooter. 

The gun’s design, combined with the powerful .40 S&W round, can cause an excessive kick.


Addressing this challenge involves a two-fold solution: improving shooting technique and possibly modifying the firearm. 

Proper grip and stance significantly reduce felt recoil. Consider professional instruction to ensure these fundamentals are sound. 

On the modification side, consider adding a recoil-reducing guide rod or upgrading to a heavier aftermarket barrel. 

Both modifications can help absorb and dissipate the energy causing the recoil, effectively reducing its impact on the shooter.

2. Difficulty in Concealment


The difficulty in concealing the Glock 27 Gen 4 can be ascribed to its width, which is slightly larger for a subcompact firearm. 

The gun’s wider frame may cause it to print through clothing, making it more noticeable when trying to carry concealed. 

The Glock 27’s width can undermine its concealability, particularly when worn with tighter clothing or carried in certain holster styles.


To overcome concealment challenges, choice of holster and clothing adjustments are key. 

Opt for a holster designed for concealment, like an inside-the-waistband (IWB) holster, which keeps the gun close to the body and minimizes printing. 

Holsters with adjustable ride height and cant can further enhance concealability. 

Also, adjusting clothing choices, such as wearing patterned shirts or slightly looser clothing, can also help disguise the outline of the gun. 

Remember, effective concealment is about blending in and not drawing attention.

3. Troublesome Magazine Release


The troublesome magazine release on the Glock 27 Gen 4 can primarily be traced back to its design. 

The position and size of the button can make it difficult for some shooters to engage, especially those with smaller hands or shorter fingers. 

This results in slower, less efficient magazine changes. The design and position of the magazine release hinder its accessibility, slowing down magazine changes.


A viable solution for this issue involves replacing the stock magazine release with an extended aftermarket option. 

These extended releases protrude more, making them easier to engage without altering your grip on the firearm. 

This can significantly improve magazine change speeds and overall firearm handling. 

An extended aftermarket magazine release can enhance accessibility, resulting in faster, more efficient magazine changes.

4. Inadequate Standard Sights


The inadequacy of the standard sights on the Glock 27 Gen 4 mainly results from their design and constituents. 

The factory sights are made of plastic and have a tendency to be less durable and prone to breakage. 

Besides, their design lacks the high-contrast coloration that facilitates quick, clear target acquisition, particularly under low-light conditions. 

The plastic construction of the standard sights compromises their durability, while their design hamstrings quick and clear target acquisition, especially in low-light scenarios.


The solution to improving sight effectiveness lies in upgrading to aftermarket sights. 

These are typically made of more durable materials like steel or aluminum and often feature designs that enhance visibility, such as high-contrast coloration or tritium inserts for night shooting. 

Some popular choices include the Trijicon HD Night Sights and the AmeriGlo Pro-Glo combination. 

Upgrading to durable, high-contrast aftermarket sights can significantly enhance sight longevity and visibility, enabling quicker, more accurate target acquisition irrespective of lighting conditions.

5. Limited Magazine Capacity


The limited magazine capacity of the Glock 27 Gen 4 stems primarily from its compact design. 

As a subcompact firearm, the Glock 27 Gen 4 is designed for concealability and ease of carry, which necessitates a smaller frame. 

However, this smaller design consequently yields less room for ammunition, resulting in a limited standard magazine capacity of 9 rounds. 

The Glock 27 Gen 4’s compact frame inherently limits its magazine capacity, accommodating only a standard 9-round magazine.


One practical solution to the limited magazine capacity issue is to invest in magazine extensions. 

These extensions add more space to the existing magazine, thereby increasing the number of rounds it can hold. 

Glock itself produces a “+2” extension that can increase capacity to 11 rounds, while aftermarket manufacturers offer even larger extensions. 

However, it’s important to remember that while these extensions increase capacity, they also increase the size of the firearm, potentially affecting concealability. 

Magazine extensions are an effective solution, increasing the Glock 27 Gen 4’s capacity while slightly altering its compact profile.

6. Uncomfortable Grip for Larger Hands


The discomfort experienced when holding the Glock 27 Gen 4 for those with larger hands can be attributed to the gun’s compact frame. 

This subcompact firearm is designed to be small and easily concealable, which often means a smaller grip size. 

For individuals with larger hands, this can result in an uncomfortable and less secure grip on the firearm, as there might not be enough surface area on the grip to fully accommodate larger hands. 

The limited grip space can lead to the pinky finger overlapping the bottom of the grip or hanging off it, which might impact the user’s control and stability while shooting.


To address the uncomfortable grip for larger hands, several modifications can be considered. 

Firstly, adding grip extensions can provide extra surface area, thus ensuring a more secure and comfortable grip. 

Grip extensions not only accommodate the pinky finger that usually hangs off the grip, but also distribute the firearm’s recoil impact over a larger area, effectively reducing discomfort. 

Another solution is to use a grip sleeve, which can bulk up the grip and provide a more secure, comfortable hold. 

Lastly, the use of an extended magazine can also provide an additional gripping surface. The use of grip extensions, grip sleeves, and extended magazines can help accommodate larger hands, enhancing comfort and control when handling the Glock 27 Gen 4.

7. Stiff Trigger Pull


The stiff trigger pull of the Glock 27 Gen 4 is largely a consequence of its factory settings geared toward ensuring safety. 

Glock firearms come with a relatively harder trigger pull to prevent accidental discharges. 

While this feature is crucial for safety, it can potentially hamper accuracy as it requires more force to fire and can lead to the gun shifting during the trigger pull. 

The stiff trigger pull originates from Glock’s commitment to safety, potentially sacrificing accuracy for unintended discharge prevention.


The remedy for a stiff trigger pull lies in modifying the trigger assembly with an aftermarket trigger kit. 

These kits generally offer adjustable trigger pull weights, allowing users to fine-tune the force necessary to discharge the firearm to their preference. 

This results in a smoother, more controlled trigger pull, ultimately improving accuracy. It’s important, however, to balance this adjustment, ensuring that the trigger pull is not too light to compromise safety. 

Trigger kits offering adjustable pull weights can alleviate stiffness, improving accuracy without compromising firearm safety.

8. Challenging Disassembly


The challenging disassembly of the Glock 27 Gen 4 is primarily due to its compact design and intricate internal mechanics. 

In an effort to streamline the size of the firearm for more practical everyday carry, several components have been tightly fitted. 

This may make it difficult for users, especially beginners, to disassemble the firearm for cleaning or maintenance without the risk of damaging its parts. The compact design and complex internal structure can make disassembly a challenging process, particularly for novice users.


The solution to challenging disassembly lies in learning the correct dismantling technique and possibly investing in tools specifically designed for Glock disassembly. 

Many tutorials and guides are available online to help users understand the disassembly process step-by-step. 

For those uncomfortable with disassembling the firearm on their own, professional gunsmiths can provide assistance. 

Further, Glock disassembly tools, which are designed to safely and appropriately interact with the firearm’s components, can prove beneficial. 

Adequate education, professional assistance, and appropriate tools can simplify the disassembly process, reducing the risk of damage to the Glock 27 Gen 4.

Given its small size, components are subject to high levels of stress when the firearm is used, especially under rigorous conditions. 

Over time, these stress levels can lead to accelerated wear and tear on the firearm’s components. 

The Glock 27 Gen 4’s compact nature and frequent usage contribute to higher stress levels, resulting in rapid component wear.


A viable solution to mitigate rapid component wear is regular and thorough maintenance. 

Cleaning the firearm after each use and ensuring it’s properly lubricated can greatly reduce the wear on its components. 

Moreover, replacing parts that are prone to faster wear, like the recoil spring assembly, at regular intervals can help prolong the overall life of the firearm. 

Regular maintenance, proper lubrication, and timely component replacement can help counteract the Glock 27 Gen 4’s rapid component wear.

10. Subpar Accuracy at Long Range


Subpar accuracy at long range with the Glock 27 Gen 4 can be attributed mainly to its short barrel length and inherent sight radius. 

Given its compact size, the Glock 27 Gen 4 has a shorter barrel, and a consequently short sight radius, which can limit accuracy at farther distances. 

The short barrel length and sight radius are inherent to the Glock 27 Gen 4’s design to ensure compactness and concealability, but these factors can hamper long-range accuracy.


To enhance the Glock 27 Gen 4’s long-range accuracy, users may consider using different sighting systems or practicing with the firearm at varying ranges.
