Glock 19 Magazine Guide

The Glock 19 is loved by many for its versatility, reliability, and compact design. Billed by Glock as “The all around talent,” it’s the perfect any-use handgun, making it an excellent choice for concealed carry, home defense, and even some fun in competition shooting! Plus, with its popularity among law enforcement and the military, it has earned a solid reputation and plenty of support from aftermarket Glock 19 accessories. It is another “Goldilocks” size firearm that fits the bill for virtually any use. 

Glock 19 Overview 

The versatile Glock 19 9mm pistol is a great fit in the average-sized hand, measuring 7.36 inches in length, 1.26 inches in width, and weighing just over 30 ounces with a loaded magazine. It includes Glock’s patented SAFE ACTION® System, a fully automatic safety system consisting of three passive, independently operating, mechanical safeties. 

Glock 19 Variations 

G19 Gen4: The Glock 19 Gen4, chambered in 9 mm Luger, offers robust and accurate shooting with its compact size and high magazine capacity. Its modular back strap adjusts to any hand, and the reversible magazine catch suits both left- and right-handed shooters.

G19 Gen5: The Glock 19 Gen5 in 9mm Luger is a versatile option with its smaller size. Its new frame lacks finger grooves but can be customized with different back straps. Reversible magazine catch and ambidextrous slide stop suit both left and right-handed shooters. Barrel rifling and crown were slightly modified for greater precision.

G19X: Glock’s first “Crossover” pistol, the G19X, combines the Glock 17 frame with the Glock 19 slide, featuring a coyote-colored finish with an improved nPVD coating for corrosion resistance. It includes the Glock Marksman Barrel, no finger grooves, ambidextrous slide stop levers, and a lanyard loop.

Capacity Options for the Glock 19

Glock 19 enthusiasts can select from factory magazine capacities ranging from 10 to 33 rounds, depending on their G19 model. Additionally, other manufacturers provide alternative magazines for the Glock 19. Extended magazines and magazine extensions increase round capacity with only a minor rise in size and weight. Longer extended mags and extensions also extend the grip, improving handling. 

Critical Considerations: Materials, Construction, and Feeling-in-Hand

When choosing a magazine for your Glock 19, think about materials, build quality, and how it feels in your hand. These elements significantly impact the firearm’s performance and your overall experience. Let’s go over these and other key factors to identify the ideal Glock 19 magazine. 

Materials 

The visual appeal of a magazine can boost the overall experience of owning and using a firearm, so how materials look matters. OEM magazines usually have a sleek, minimalist look that matches the Glock 19’s style. Aftermarket options differ greatly, with some providing colorful finishes or windowed designs to show remaining rounds. Although looks are secondary to functionality, they still influence consumer choice.

OEM magazines for the Glock 19 are crafted from high-quality steel-lined polymer, offering a good mix of durability and lightweight design. These magazines are engineered to work perfectly with the Glock 19, ensuring reliable feeding and extraction.

Aftermarket magazines are available in various materials, including aluminum, steel, and different polymer blends. Some are designed to match the quality and dependability of OEM magazines, while others may reduce performance to lower costs. Always check the manufacturer’s reputation and the materials used in construction, as these factors greatly influence the magazine’s reliability and lifespan.

Construction 

Durable construction is essential when selecting magazines. The materials involved directly affect how well the magazine withstands wear, impact, and environmental factors. OEM magazines typically have a robust build, offering dependable performance over time. Although some aftermarket brands also provide durable options, it’s crucial to check user reviews and reliability ratings to avoid issues like feeding problems or breakage during heavy use.

Feeling In-Hand 

The grip feeling a magazine provides is crucial, especially in high-pressure situations. A better grip can greatly enhance handling and control. Aftermarket magazines often feature textured surfaces or ergonomic designs that improve traction, even in tough conditions. A secure grip helps prevent slippage, allowing users to maintain a firm hold on their firearm.

A magazine that feels right in the hand, both when loading and unloading, and during shooting, is vital for accuracy and user confidence. A suitable magazine can offer a more natural grip angle or increase grip length for comfort. Solutions like aftermarket base plates can customize the gun’s ergonomics to better suit the shooter, leading to improved control and accuracy. 

Functional Impact on Handling and Shooting

The selection of a magazine for the Glock 19 can significantly impact its overall balance, handling, and performance. For example, using extended magazines increases the round capacity, which can also alter the firearm’s weight distribution. This change in weight can influence how the gun feels in the user’s hand, potentially affecting handling characteristics. As a result, the choice of magazine can have implications for the user’s shooting technique and comfort level while operating the firearm.

Compatibility Across Other Glock Models 

The Glock 19 can use all Glock 17-compatible magazines, as well as its own 15-round double-stack magazines. The magazines will stick out and won’t sit flush, but they function properly. However, Gen 5 magazines are incompatible with the Glock 19X; the grip features a newly designed lip that prevents the Gen 5 magazine’s baseplate from seating properly.

The same OEM Glock 19 magazine comes with a Glock 49, as it’s a crossover between the 19-frame and the 17-slide. A Glock 19 15-round magazine also fits in your Glock 26, though it extends past the bottom of the grip. Many users of the Glock 26 for self-defense choose Glock 19 magazines for increased capacity.

What Makes a Reliable Magazine? 

The reliability of a magazine is crucial for firearms, as it affects both their performance and safety. Here’s what to consider for the Glock 19: 

Factory vs. Aftermarket Reliability

Factory Glock (OEM) magazines always ensure compatibility and reliability. They undergo rigorous testing to meet strict standards and feature superior materials and construction tailored to the firearm.

Aftermarket magazines can vary greatly in quality. Some are well-made and perform reliably, while others may have feeding issues or faulty locking mechanisms. To achieve optimal performance, users should research and select reputable aftermarket brands known for their reliability. 

Magazine Follower Design

The follower’s design is vital to consistent feeding. A good follower allows smooth movement and prevents ammunition from tilting, which can cause malfunctions. OEM magazines usually have a follower designed specifically for that firearm, ensuring reliability.

Aftermarket followers vary, so consider their shape and contour carefully. A poorly shaped follower may create friction or hinder the last rounds from feeding correctly, leading to jams or misfeeds. 

Spring Strength and Feeding Consistency

The spring’s strength is essential for reliable feeding. A spring with proper tension ensures rounds chamber smoothly. Too strong a spring can make loading difficult, while a weak spring risks feeding failures, especially on the last rounds.

High-quality OEM springs are designed for durability, but aftermarket springs may not always meet these standards. Some aftermarket options provide upgraded springs to improve feeding, but verifying compatibility with your Glock 19 is crucial 

Glock 19 Accessories 

To enhance the functionality and usability of your Glock 19, aftermarket magazine upgrades can be highly beneficial. Many Glock 19 accessories provide practical advantages and can enhance your shooting experience. Here are some popular options to consider:

Glock 19 Sleeves and Adapters 

Using sleeves or adapters to extend magazines for a Glock 19 provides a practical way to increase ammunition capacity without sacrificing grip or functionality. These accessories allow shorter grips to securely hold longer magazines, ensuring a better fit and improved control. Adding a sleeve or adapter lets users enjoy increased magazine capacity while maintaining comfort during shooting. To achieve optimal performance, it is important to select compatible and reliable accessories for the Glock 19.

Base Plates and Extensions

Base plates and magazine extensions are popular upgrades for Glock 19 magazines. They increase capacity without significantly enlarging the magazine. Base plates add height, making handling and reloading more convenient. Many extensions are designed ergonomically to improve grip, offering a more comfortable and secure hold in critical moments.

Magazine Sleeves

Magazine sleeves are ideal for Glock 17 magazine users who want to fit these larger mags into a Glock 19. They modify the size of the magazines to fit the smaller grip, enabling users to enjoy the higher capacity of G17 magazines without sacrificing comfort. Often textured for better grip, these sleeves help prevent slippage and keep the magazine secure during use. This upgrade is particularly useful for Glock owners who already possess G17 magazines and want to maximize their versatility. 

Colored Followers or Indicators

Adding colored followers or indicators to your magazines is a straightforward yet impactful way to improve functionality. These colored followers enable quick visual checks of remaining rounds, enhancing situational awareness during reloads. Some aftermarket options include high-visibility colors or markings to alert you when the magazine is almost empty. This upgrade is especially useful in low-light conditions, allowing you to stay aware of your ammunition status without needing to manually count rounds.

Popular Use Cases for the Glock 19

Who needs Glock 19 mags? Everyone who carries this incredibly popular handgun. 

EDC (Everyday Carry)

Calling the Glock 19 a “compact” EDC handgun feels weird. Many people actually view the 19 and similarly sized handguns as duty weapons. While the Glock 19 and its look-alikes are popular among police forces and are fielded by numerous military units, in 1988, the term “compact” was an accurate description compared to the Glock 17. Glock hit a home run with the Model 17, but the 19 was a grand slam. Even after more than 30 years, the Glock 19 remains the benchmark against which all other semi-automatic handguns are measured. 

Competition

The Glock 19 can be a suitable choice for competition shooting, particularly in IDPA Stock Service Pistol (SSP), since targets are only 20 yards or less. Outdoor USPSA Productions are typically 50 yards or more, so a G19 may not be the best choice. 

Range Use

The Glock 19 is an excellent firearm suitable for range use, offering a smooth experience for both new and experienced shooters. Its standard 15-round magazine supports focused training sessions without being overwhelming for beginners, while options up to 33 rounds offer longer shooting sessions with fewer reloads. Aftermarket accessories allow shooters to customize magazine sizes for practice, enabling them to improve their skills with various capacities. 

Duty/Military

The Glock 19 has maintained significant popularity among law enforcement and military users due to its balance of size, capacity, and reliability. As a versatile 9mm pistol, it strikes the perfect compromise between a compact design for concealed or easy everyday holstered carry and the firepower necessary for various operational scenarios. 

Additionally, military personnel appreciate the Glock 19 for its durability and ease of maintenance, which are critical in demanding environments. Its solid reputation and extensive aftermarket support further enhance its appeal, making the Glock 19 a trusted sidearm for both active duty and tactical operations.

Cost & Value of Glock 19 Magazines 

When considering the purchase of magazines for the Glock 19, it’s essential to evaluate the cost and value associated with both OEM and aftermarket options. The following table outlines key factors, including price ranges for OEM magazines compared to aftermarket alternatives, performance for price, construction materials, and price ranges.

Legal Considerations 

When selecting a magazine for your Glock 19, it’s essential to understand the legal landscape surrounding firearm magazines, as these laws can vary significantly from state to state.

State Restrictions

Fourteen states plus the District of Columbia limit magazine capacity, typically to 10 rounds. These laws aim to improve public safety, but can significantly impact gun owners’ options. Buyers should check their state’s rules before purchasing magazines to stay compliant and avoid legal issues. Additionally, some states have specific definitions or classifications for what counts as a high-capacity magazine, making it essential to stay informed.

Magazine Locks & Limiters

For states with strict magazine capacity restrictions, some manufacturers offer magazines with built-in locks or limiters. These devices reduce the magazine’s capacity to comply with local laws and can be installed internally to limit the number of rounds. This allows gun owners to stay within legal limits while still using their preferred aftermarket magazines. However, users should confirm that these modifications do not affect the magazine’s functionality or reliability.

“Freedom Series” or Compliant Variants

XTech Tactical’s Freedom Series magazines are designed in response to restrictive state laws; a few other makers also offer compliant magazine options. These magazines are tailored to meet the legal standards of different areas while maintaining functionality and durability. Although they may look and feel like regular magazines, they include features such as capacity limits or other modifications to comply with local laws. Choosing these compliant models enables gun owners to equip their Glock 19 effectively while remaining within legal boundaries.
