Best Glock 19 Upper

What is Glock 19 upper?🧐

This term refers to the upper portion of a Glock 19 pistol, which is a popular semi-automatic handgun. In a firearm like this, the upper consists of several components, including the slide – is the uppermost part of the pistol, which houses the barrel and other internal components; the barrel – is the tube through which the bullet travels when fired; the recoil spring and guide rod – are components that work together to manage the recoil of the firearm; the extractor – a small claw-like mechanism that grips the spent casing and pulls it out of the chamber after firing; the striker assembly.

The features of a Glock 19 upper assembly, which includes the slide and related components, contribute to the overall functionality, reliability, and performance of the Glock pistol. Here are some common features:

❇️ Glock slides are typically made from a durable and corrosion-resistant material, often stainless steel or a steel alloy. Some aftermarket options might use different materials like lightweight metals or polymers.

❇️ The slide might have various finishes for both aesthetics and protection against wear and corrosion. Common finishes include matte black, silver, and various coatings.

❇️ Some aftermarket slides have additional cuts or ports that can reduce overall slide weight, improve slide manipulation, and enhance aesthetics.

❇️ Many aftermarket slides offer a cut specifically designed for mounting mini red dot sights like the Trijicon RMR or similar models, which can enhance target acquisition.

How to assemble such an upper?🛠️

Assembling a Glock 19 upper can be a detailed process and requires careful attention to ensure safety and proper function. However, if you have experience with firearms and are confident in your abilities, here’s a general overview of how to assemble it:

🛑 Note: Before starting the assembly, ensure the firearm is unloaded and the magazine removed. Always follow proper firearm safety protocols.

➡️ Make sure you have all the necessary components for the upper assembly, including the slide, barrel, recoil spring assembly, sights, and any other parts you plan to install.
➡️ Before assembly, clean all components to remove any dirt, debris, or residues. Inspect each part for any signs of damage or wear.
➡️ Slide the barrel into the front of the slide, ensuring it’s properly aligned with the slide cuts and the barrel hood fits into the breech opening. The barrel lug should align with the slide’s ejection port.
➡️ Assemble the recoil spring onto the guide rod. Insert the guide rod and recoil spring assembly into the slide’s recoil spring channel, making sure it’s seated properly.
➡️ Install the extractor into the appropriate slot on the slide. Make sure the extractor claw is oriented correctly. Install the firing pin safety plunger and spring.
➡️ Insert the firing pin assembly into the slide’s firing pin channel, ensuring it’s properly seated and aligned.
➡️ Place the slide cover plate over the rear of the slide. Use a tool to depress the firing pin safety plunger, allowing the cover plate to slide into place.
➡️ If your slide doesn’t have sights installed, you can install the front and rear sights according to the manufacturer’s instructions. Ensure they are properly aligned and secure.
➡️ Double-check all components to ensure they are properly installed and aligned. Check the movement of the slide to make sure it cycles smoothly.
➡️ With the upper assembly complete, you can reattach it to the lower frame of the Glock 19 by sliding the two parts together. Ensure the slide fully engages with the frame’s rails.
➡️ Perform a function test by manually cycling the slide to ensure it moves smoothly and the trigger resets properly. Verify that the safety mechanisms are functioning as intended.


What sights are the best on this upper?

✒️ The choice of sights for your Glock 19 upper depends on your specific preferences, shooting style, and intended use. There are several types of sights available, each with its advantages. Here are some popular options:

Standard sights consist of three dots: one on the front sight and two on the rear. They provide a simple and intuitive aiming method. These sights are commonly found on most Glock pistols and are suitable for general use.

Night sights have illuminated dots or tritium inserts that glow in low-light conditions. They’re useful for self-defense and home defense scenarios where visibility might be limited. Night sights ensure you can aim accurately even in the dark.

Fiber-optic sights use a colored, light-gathering rod on the front sight to create a highly visible aiming point. They work well in well-lit conditions and can help improve target acquisition speed.

Red dot sights are becoming increasingly popular for handguns. They offer a clear and unobstructed sight picture, and the red dot provides fast target acquisition. Mounting an RDS might require a slide cut, so ensure your Glock 19 upper is compatible.

✅ Some sights combine different technologies, such as combining fiber optics with tritium inserts. This provides both daytime visibility and low-light illumination.

Adjustable sights allow you to fine-tune your point of impact for different loads or distances. They are particularly useful for competition shooters who need precise adjustments.

✅ If you plan to mount a suppressor on your Glock 19, you might need suppressor-height sights to co-witness with the red dot sight or to ensure proper sight alignment above the suppressor.

😉 Ultimately, the “best” sights for your upper depend on your shooting goals. Consider factors like your shooting environment (daytime vs. low-light), shooting distances, and any specific requirements you have.

What materials are the uppers made of?

☑️ The choice of materials can affect factors such as durability, weight, corrosion resistance, and overall performance. Glock pistols are known for their reliable polymer frames and steel slides. Here are the materials commonly used in Glock 19 uppers:

🔷 Stainless steel is a common material for Glock slides due to its corrosion resistance and durability. It can be treated with various finishes to enhance these qualities. Stainless steel slides are robust and can withstand a variety of environmental conditions.

🔷 Carbon steel is another option for slides. It’s strong and durable, but it might require additional protective coatings to prevent corrosion. Carbon steel slides can be more affordable compared to stainless steel.

🔷 Some aftermarket Glock slides are made from aluminum alloy. Aluminum slides are lightweight, which can contribute to reduced overall pistol weight. However, they might not be as durable as steel slides and can wear faster over time, especially with high-round-count shooting.

🔷 Titanium is lightweight and strong, making it an attractive choice for custom slides. It’s corrosion-resistant and can provide a unique aesthetic. However, titanium slides can be expensive and might require specific finishes or treatments to enhance durability.

📌 When choosing the best material for your Glock upper, consider factors such as your intended use, budget, and preferences. Always prioritize the reliability and safety of your firearm when selecting materials for aftermarket parts.

Is a black nitride finish suitable for it?

😉 Yes, a black nitride finish is suitable for a Glock 19 upper. Black nitride, also known as Melonite or Tenifer, is a popular surface treatment used on firearm components, including slides. It offers several benefits:

🔰 Corrosion Resistance: Black nitride is known for its exceptional corrosion resistance. It forms a protective layer on the surface of the material, which helps guard against moisture, sweat, and other environmental factors that can cause rust and corrosion.

🔰 Durability: The black nitride finish is hard and wear-resistant, which means it can withstand the friction and abrasion that occur during slide cycling and regular use. This extends the lifespan of the upper and maintains its appearance over time.

🔰 Reduced Friction: The smoothness of the black nitride finish can contribute to reduced friction between moving parts, allowing for smoother slide movement and potentially improved overall firearm function.

🔰 Heat Resistance: Black nitride is also known for its heat resistance. It can withstand the high temperatures generated during firing without significant degradation, which is especially important for components like slides.

🔰 Aesthetics: The black color of the nitride finish provides a sleek and uniform appearance to the Glock upper. It enhances the visual appeal of the firearm while also contributing to a low-profile, tactical look.

🔰 Ease of Maintenance: The smooth surface of the black nitride finish is relatively easy to clean and maintain. It can be wiped down with minimal effort, and its resistance to corrosion means it’s less prone to rust buildup.

❗ Keep in mind that while black nitride offers many advantages, the quality of the finish also depends on the manufacturer’s processes and the materials used. Reputable manufacturers will ensure proper application to achieve the desired benefits.

Does dry firing damage a Glock?

💥 Dry firing a Glock pistol, which means pulling the trigger without a live round in the chamber, generally does not cause damage to the firearm. Glocks, like many modern firearms, are designed to handle dry firing without significant negative effects. However, there are a few important points to consider:

🔶 Modern Design: Glocks and many other modern handguns have features in place to absorb the impact of the firing pin when the trigger is pulled, even if there’s no cartridge to ignite. This reduces the risk of damage to the firing pin and other components.

🔶 Regular Practice: Dry firing can be a useful practice tool for improving your shooting skills, such as trigger control and sight alignment. It allows you to focus on your technique without the recoil and noise of live ammunition.

🔶 Check the Chamber: Before dry firing, always ensure that the chamber is empty and that there is no live ammunition in the firearm. Follow proper firearm safety procedures and treat every firearm as if it were loaded.

🔶 Use Snap Caps: While not always necessary, using snap caps (dummy rounds) can add an extra layer of protection to your firearm’s firing pin. Snap caps are designed to absorb the impact of the firing pin during dry firing, reducing wear on the firing pin and other components.

🔶 High Volume and Repeated Dry Firing: While occasional dry firing for practice is unlikely to cause harm, excessively high volume or repeated dry firing over an extended period could potentially contribute to wear on internal components. However, this would require a significant amount of dry firing, and the typical shooter’s dry firing practice is unlikely to cause noticeable damage.

😀 In summary, the occasional dry firing of a Glock pistol as part of the practice is generally considered safe and won’t cause damage to the firearm.

What is the difference between Gen 3 and Gen 4 Glock slide?

🔍 The Glock Gen 3 and Gen 4 slides have several differences, ranging from design improvements to ergonomics and features. Here are some of the key differences between the two generations:

🟣 Grip Texture: Glock Gen 3 slides feature the traditional Glock grip texture, which consists of square-shaped checkering on the front and back straps. Glock Gen 4 slides introduced a more aggressive grip texture known as the RTF (Rough Texture Frame). This texture provides better traction and control, especially in adverse conditions.

🟣 Interchangeable Backstraps: Glock Gen 3 pistols have a fixed grip design with no interchangeable backstraps. Shooters have to choose a grip size that suits them best. Glock Gen 4 slides come with multiple interchangeable backstraps and grip inserts, allowing users to customize the grip size and shape to their preference.

🟣 Recoil Spring Assembly: Gen 3 Glocks typically use a single recoil spring assembly. Gen 4 Glocks introduced a dual recoil spring assembly. This design is intended to reduce felt recoil and improve durability over time.

🟣 Magazine Release Button: The magazine release button on Gen 3 Glocks is a standard size and non-adjustable. The Gen 4 Glock slide features a reversible magazine release button that can be switched to accommodate left-handed shooters. It also has an enlarged magazine release button for easier manipulation.

🟣 Frame Design: The frame of Gen 3 Glocks is characterized by its traditional grip texture and finger grooves on the front strap. Gen 4 Glocks feature the RTF grip texture and the option to remove the finger grooves for a smoother grip.

🟣 Slide Stop Lever: The slide stop lever on Gen 3 Glocks is a non-ambidextrous design. Gen 4 Glocks have an enlarged and reversible slide stop lever to accommodate left-handed shooters.

🟣 Magazine Floor Plate: Gen 3 magazines have a standard, flat floor plate. Gen 4 magazines have a slightly extended, scalloped floor plate design.

At this point, I’m in a bit of a pickle as I’m desperately searching for an affordable slide (around $200) that doesn’t compromise on quality. My requirements are quite specific: I need a slide that can accommodate a Vortex Venom optic, boasts a burnt bronze finish, and is compatible with my G19. Does anyone happen to know of a reliable seller that fits the bill? Your help would be greatly appreciated.

    The Brownells 9mm Gen3 Windowed Slide has proven to be quite reliable. While they might not be the most attention-grabbing in terms of appearance, they offer front serrations, and an RMR cut, and are constructed with solid tolerances.

      Considering your budget, I suggest looking into the TacFire Glock Slide With Cover Plate. It is very durable with a Cerakote graphite finish – this change greatly improved my situation.

        I own a G19 Gen3, which I initially acquired when living in a state that wasn’t particularly friendly to gun owners. Now, I’m looking to make some modifications to it, especially considering I have a red dot optic. I plan to go for an aftermarket RMR cut slide and a new barrel. However, I’m hesitant to make any alterations to the stock slide itself, just in case I ever find myself needing to go back to that state. I’d greatly appreciate any suggestions, recommendations, or insights you might have to offer.

          When it comes to aftermarket slides, the G19.3 is notably one of the most well-served options out there. If you’re considering your options, it might be helpful to narrow down based on factors like quality and budget. For those on a budget, you could explore the American Tactical Arms ATA19 Badger Stripped Slide.

            I’ve been in the market for a Gen 3 slide and had my eye on the Matrix Arms MX19 Delta Pistol Slide. I’m curious if anyone here has any alternate recommendations or personal reviews about it.

              I can vouch for the Matrix Arms MX19 Delta Pistol Slide – it offers fantastic quality with tight tolerances, solid performance, and a visually appealing design. If you’re looking to take things up a notch, consider pairing it with a compensator. The combination will transform your Glock into an impressively flat shooting firearm that’s bound to catch everyone’s attention at the range.

                    I’d like to recommend the American Tactical Arms ATA19 Badger Complete Ambidextrous Slide. In my experience, I haven’t encountered any issues after firing over 300 rounds through it. Just thought I’d share my positive experience with you.
