Maintenance 🔰

Maintaining your Glock upper is crucial to ensure the longevity and functional reliability of your firearm. Start by disassembling your Glock, but remember, safety first: ensure the gun is unloaded before you begin.

  1. 🚩 Remove the Slide: After ensuring your Glock 17 is safe to disassemble, pull back the slide, press down the slide lock and push the slide forward and off the frame.
  2. 🚩 Remove the Recoil Spring: Within the slide assembly, you’ll find the recoil spring. Push forward on the spring slightly, and lift to remove it.
  3. 🚩 Remove the Barrel: With the recoil spring removed, you can pull the barrel out of the slide.
  4. 🚩 Clean the Components: It’s recommended to use a specialized gun cleaning solution. Apply the solution to a cloth or use a cleaning brush to scrub off any residue or build-up.
  5. 🚩 Lubricate: Apply lubricant to the barrel, the inside of the slide, and the recoil spring. This reduces wear on these components during use.
  6. 🚩 Reassemble: Finally, replace the barrel and recoil spring in the slide, then attach the slide back onto the frame.

Regular maintenance and cleaning of your upper ensures peak performance and extends the lifespan of your firearm. Always refer to the manufacturer’s instructions for specifics regarding your model.

FAQ ❓

What materials are Glock 17 uppers made from?

It is meticulously crafted using a combination of high-quality materials to ensure unrivalled durability, longevity, and optimal performance. The slide, for instance, is expertly fashioned from a specially treated metal called Tenifer. This remarkable material not only imparts a distinctive matte finish to the Glock but also endows it with exceptional resistance to wear and tear, thanks to its incredible durability and corrosion resistance.

Moreover, the barrels of the Glock 17 are meticulously constructed from cold hammer-forged steel, incorporating polygonal rifling. This sophisticated manufacturing process ensures not only longevity but also superior accuracy, allowing shooters to achieve precise and consistent results. And that’s not all – Glock employs a nitration process to further enhance the surface of its metal components. This process hardens and refines the metal, providing an additional layer of protection against corrosion and wear, ensuring the Glock 17’s resilience even in the most challenging conditions.

What are the best Glock 17 Upper Parts?

In general, the Glock upper parts include the following components:

  1. 🟤 Slide: The uppermost part of the pistol, which houses the barrel, recoil spring assembly, and other internal components. It also features serrations for cocking and may include an optics-ready cut.
  2. 🟤 Barrel: The tube through which the bullet travels when fired. For the Glock 17, this is a 9mm barrel.
  3. 🟤 Recoil Spring Assembly: Comprising a recoil spring and guide rod, it absorbs and manages recoil energy during firing.
  4. 🟤 Firing Pin Assembly: This assembly includes the firing pin, firing pin spring, and firing pin safety. It’s a critical part of the firearm’s ignition system.
  5. 🟤 Extractor: Responsible for extracting and ejecting spent cartridge cases from the chamber.
  6. 🟤 Extractor Depressor Plunger: Helps control the extractor’s movement and ensures reliable extraction and ejection.
  7. 🟤 Striker Assembly: Comprising the striker (firing pin), striker spring, and striker safety, this assembly is vital for firing the gun.
  8. 🟤 Sights: These components provide aiming reference points and can be fixed, adjustable, or night sights, depending on the model.
  9. 🟤 Top Slide Cover Plate: A removable plate on the rear of the slide that provides access for maintenance and customization.
  10. 🟤 Recoil Spring Cups: Sit at the front of the recoil spring assembly, guiding the recoil spring during cycling.
  11. 🟤 Firing Pin Safety: A safety feature that prevents the firing pin from moving forward unless the trigger is pulled.
  12. 🟤 Firing Pin Safety Spring: The spring associated with the firing pin safety, ensures its proper function.
  13. 🟤 Sight Mounting Options: Some slides offer mounting options for various optics or red dot sights, which may include adapter plates or cutouts.

These are the fundamental upper parts you’ll find in most Glock 17 pistols. Keep in mind that variations and aftermarket upgrades exist, allowing for customization and enhanced performance based on individual preferences and needs. Proper handling, maintenance, and assembly are crucial when dealing with any firearm components. Always follow safety guidelines and consult official Glock documentation or a qualified gunsmith if you have questions or need assistance.

What generation Glock 17 upper should I get?

When deciding which generation of Glock Upper to get, most experts recommend going with a Gen 3 model for the best compatibility and aftermarket support. Here are some key considerations on Gen 3 vs. other gens:

  • ⚪ Gen 3 Glock uppers will fit and function on Gen 1, 2, and 3 Glock frames. Gen 4 uppers may require some modification to work on earlier frames.
  • ⚪ Gen 3 has enough enhancements over Gen 2 (such as rail accessory mounting and grip texturing) while avoiding some compatibility issues that arose with Gen 4 models.
  • ⚪ Gen 3 models have a well-proven track record for reliability and durability over tens of thousands of rounds. Gen 3 uppers are often found at more affordable prices on the used market.
  • ⚪ While Gen 4 and Gen 5 have some incremental improvements, the Gen 3 upper offers the best compatibility and aftermarket support for most users. Those seeking the latest upgrades may want a Gen 5 upper but expect less aftermarket accessory options.
How do I ensure my Glock 17 upper fits properly on my frame?

Ensuring a proper fit of your upper on your frame is crucial for its safe and optimal operation. Here are some steps you can follow:

  1. 📌 Check Compatibility: Before installing the upper, make sure it’s compatible with your Glock’s frame. The upper typically fits on the standard Glock 17 frame as well as other compatible models.
  2. 📌 Clean and Inspect: Always clean and inspect both the frame and the upper before installation. Any debris can interfere with the fit and function of the firearm.
  3. 📌 Slide Alignment: When installing, align the slide with the rails on the frame. The slide should fit onto the rails without excess force.
  4. 📌 Push and Secure Slide: Push the slide back onto the frame gently. It should move smoothly without catching or requiring excess force. It’s secured when you hear a click.
  5. 📌 Function Testing: After installation, perform a function test by pulling back the slide to the rear and releasing it, allowing it to go forward on its own. Test the trigger to ensure it resets properly.

If the upper doesn’t fit properly or if the slide doesn’t move smoothly, do not force it. Instead, consult the Glock 17 owner’s manual or a professional gunsmith for assistance. A well-fitted upper ensures the safe and reliable operation of your firearm.

What is the difference between a Glock 17 and Glock 17L upper?

The main differences between a standard Glock 17 upper and a Glock 17L upper are:

  • Barrel length – The Glock 17L has a longer 6.02-inch barrel compared to the 4.49-inch barrel on a regular Glock 17.
  • Slide length – The slide is longer on the Glock 17L to accommodate the longer barrel.
  • Sight radius – Due to the longer slide and barrel, the Glock 17L has a longer sight radius of 8.53 inches vs. 6.77 inches on the Glock 17. This increased sight radius improves accuracy potential.
  • Weight – The Glock 17L upper weighs slightly more than the standard upper due to the extra barrel and slide length.
  • Models – The Glock 17L upper is only available in Gen 1-3 while the upper for Glock 17 comes in Gen 1-5.

Other than the differences in barrel length, slide length, sight radius and weight, the function of the Glock 17L upper is basically the same as the Glock 17 upper. The increased sight radius of the 17L is appealing for target shooting.

Conclusion 🤩

The Glock 17 upper stands as a testament to Glock’s commitment to innovation, quality, and performance. It offers enhanced accuracy, increased magazine capacity, reduced recoil, and accessory compatibility, all while adding a layer of versatility with its compatibility across multiple Glock frames. The maintenance and installation processes, although detailed, are manageable for users at all levels of expertise. This perfect balance of functionality, durability and ease of use makes the upper a valuable addition to any firearm enthusiast’s collection.

I’ve been thinking about getting a Glock 17 upper to pair with my Glock 19 lower. Can anyone confirm if this is a viable option, and do I need any special parts to make it work seamlessly?

    Natalia

    Reply to  Pilot

    Yes, pairing a Glock 17 upper with a Glock 19 lower is a very common and viable option. The Glock 17 upper will fit and function on a Glock 19 lower without any issues since the frames are the same size, except for the grip length.
    The key things to keep in mind are:
    • 🔵 Make sure both the upper and lower are the same generation (e.g. both Gen 3). Mixing generations can cause compatibility issues.
    • 🔵 No special parts are needed for the upper or lower. The factory parts will work together seamlessly right out of the box.
    • 🔵 The only functional difference will be the shorter Glock 19 grip frame compared to a full size Glock 17 frame. This gives you a full size Glock 17 slide on a compact Glock 19 body.
    • 🔵 You can use standard Glock 17 magazines for higher ammo capacity. The magazines are cross compatible between these models.
    • 🔵 Accuracy and reliability will be on par with a factory Glock 17 pistol since the upper controls these factors.

      From my experoinse the Glock 17 upper will fit on a Glock 19 lower, but you might need to use Glock 17 magazines for reliable feeding since the upper is designed for those. It’s a great setup for those who want a longer sight radius and a bit more grip to hold onto. Just make sure to follow any local laws regarding firearm modifications.

              I’ve been using a Glock 17 upper for competitive shooting, and it’s been a fantastic choice. The reliability and aftermarket support make it easy to build a competition-ready firearm.

                I’m posting this to share a learning experience, both for myself and newcomers to firearm builds. Hopefully, some of the more experienced builders can shed light on which parts are suitable for use in a P80 build. While OEM (Original Equipment Manufacturer) parts are considered the gold standard, they can be extremely scarce and often come with a hefty price tag.

                So, I’m looking for recommendations on brands and specific parts that you, personally, trust in your builds. I’m tired of shelling out $120 or more for a basic LPK (Lower Parts Kit) – it’s eating into my ammo budget! Your insights and suggestions would be greatly appreciated. Let’s help each other find quality alternatives without breaking the bank.

                    I totally feel your pain about those. I’ve tried is the CMC Triggers LPK. They offer a nice balance between quality and affordability.

                      I’ve been using Lone Wolf parts in my builds, and I’ve been quite satisfied with the results. Their prices are reasonable
