How to Build a Glock (2023 UPDATED) Read This First

1. Select Your Pistol Frame

You must “create” the frame or receiver if you’re creating your own firearm. Only weapons created by a licensed dealer are required by federal law to be marked with specified markings, including a serial number—those who don’t have numbers or markings that are untraceable are referred to as ghost guns.

For your Glock build, we suggest the Polymer 80 Glock frame kit. When you purchase the Polymer80 Glock frame kit, it comes with a polymer frame and a jig, as well as the necessary drill bits, rear rail module, and rear rails to make the handgun, as well as the front and rear frame rail inserts. The Glock frame kit includes a stripped frame with a perfect trigger guard undercut. 

Remember to check the size of the frame. If you buy a “19” sized frame, make sure you buy parts for a “19” sized Glock as you go; otherwise, the wrong size will not function if it isn’t the same size as your frame. 

2. Choose Your Lower Parts

The lower Glock parts are the ones that will go into your pistol frame. Buying a complete Glock lower parts kit is the easiest and least expensive choice. However, if you want to customize your handgun, buying the parts separately might be the best solution for your Glock pistols.

For your Glock build, you may opt to buy a Glock parts kit or separately. The lower parts include magazine release, magazine catch spring, trigger shoe, locking block pin, trigger kit with firing pin safety and striker springs, trigger bar, trigger spring, trigger pin, slide lock spring, slide stop lever, and trigger housing with ejectors. Here’s the correct way to disassemble your Glock mag. 

3. Select Your Slide

For beginners, choose plain original slides or high-quality aftermarket Glock slides with any combination of features such as a red dot sight mounting slot, serrations, and weight-saving cuts. However, there are many custom slide options. If you have the money and abilities, there are even frames that come with blank exteriors that you can custom to look exactly what you want them to look. 

You can find complete slide assemblies; however, a slide assembly may cost you more. A slide completion kit also is more convenient since it composes all the internal parts for your slide. 

4. Choose Your Barrel

It’s simple to find the right barrel for your Glock pistol, despite many variations available. The Glock barrel is dependable and precise. You can opt to buy a factory. 

5. Pick The Slide Parts

For the slide parts, there are options. You can buy the glock slide parts kit. Unless you want “improved” parts, this kit is the way to go. Even if you wish to enhance your striker, getting this kit and using your replacement striker while saving the factory one as a backup may be a preferable alternative. Another option is the Lone Wolf slide parts kit, which is much cheaper than the previous one.  

6. Choose Your Guide Rod

The handgun guide rod is a vital but often overlooked component of the weapon. It is important not just for slide speed but also for firing strength and accuracy, and safety. 

Steel or stainless steel is used in the majority of aftermarket guide rods. These round or flat sprung captive or non-captive rods are more substantial than plastic rods, allowing them to equalize muzzle climb more effectively.
