13 Steps in Building A Glock
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.
7. Pick A Sight System
Without the appropriate sights, you can’t create a Glock pistol. If you can’t match up the bore with the aimed target, your custom glock pistol will be useless. The good news is that practically all Glock slides and sights are universally compatible, including factory and aftermarket, and changing Glock sights are quite easy, too. This means you have a lot of options when it comes to purchasing sights for your Glock pistol.
You have plenty of time to choose the best sight for your handgun, whether it’s white dots, basic black, ghost ring, Tritium night sights, fiber optic, or a big dot front. You have the option of selecting the sights that are appropriate for your custom pistol or purchasing a front sight tool and installing the sights yourself. We’ll show you the proper way to aim a Glock here.
8. Choose Your Magazine
For your magazine, there are options too. Factory Glock magazines are a no-brainer.
Especially if you’re looking for “high-capacity” magazines like the Glock 33-rounders, however, they are more expensive than other types of magazines.
9. Select The Trigger
After you’ve machined and drilled your pistol frame, it’s time to think about interior components and which trigger you’ll use. Some gun owners prefer the factory-installed Glock trigger, while others prefer a lighter, smoother, and more consistent trigger with a more noticeable let-off. When building a Glock 19, remember that the weapon’s intended use is the most important factor to consider when selecting a trigger.
10. Create Your Frame
Milling may appear hard in frame assembly, but it’s quite simple if you follow the internet instructions. To finish the last 20% of the Glock pistol frame, all you need is a drill press and an electric hand drill or cordless drill. Milling requires no complicated setup because the jig includes everything properly aligned while working on your frame.
Just remember to not use a drill press on the cross vise to drill the pinholes. The bench vise and drill are the only tools you’ll need. At the front and rear, mill off the plastic ribs above the frame rails until flush. You can file the rails flush with a flat, coarse file if you don’t have a drill press. Start by clamping the fixture in a bench vise.
The channel in front of the forward rails, where the recoil spring lives, is blocked by a plastic membrane to clear the spring tunnel. Within the visible line molded into the plastic, this must be filed away also; look out for the barrel block as you’re milling. The vertical plastic surfaces in front of the rails operate as the slide buffer and should not be eliminated. Another option is to file the material away or use a Dremel tool to grind it away. The recoil spring assembly must have sufficient clearance.
Once done milling the frame, check for the excess plastics on the frame as Too much polymer can cause problems in your gun. Once done checking, you can now install the locking block rail system and the trigger mechanism housing.
11. Assemble Your Homemade Glock
With all of the components for your slide, frame, and lower receiver, you need some basic tools to put it all together. Start by putting the safety plunger, striker assembly, extractor, plunger spring, bearing, sliding rear plate, and sights in place.
12. Test The Trigger
To make sure the trigger works, dry fire the gun. Install an empty magazine and ensure the slide locks to the rear sight by retracting it. Make sure the slide lock isn’t pulling down when the slide is fully forward.
13. Start A Function Test
Now, proper Glock pistol tuning and fitment are essential to ensure that your custom glock handgun is functioning well. During the early testing period, expect the entire system to be stiff.
Use the proper firearm lubricant along the pistol slide rails and other friction points to guarantee smooth functioning. Be cautious while having fun and allowing the system to sort itself out. Incompatibility concerns cause the majority of testing issues. Make sure that the Glock slide and barrel are suitable.
Yes, it is legal to build a glock at home. However, this only relates to law enforcement. This activity, as well as some firearms, may be prohibited in your state, and you must apply for the approval of NFA Firearms or ATF (short-barreled rifles, silencers, etc.)
No, it’s not dangerous to build a glock if you have basic firearm knowledge and familiarity with common tools regarding handling a gun. However, it is not a smart idea for those new and has no experience in handling a gun. Making a mistake can be harmful, even deadly.
It depends. Building a new one is more expensive than buying a full gun. However, there are different standard Glock parts that you can use as an alternative if you don’t want to spend too much money.
It would take about 15 minutes to 30 minutes to build your own glock and much shorter if you purchased ready-to-use kits.
Final Thoughts On Building A Glock
For some, building their own guns gives them a satisfying feeling and additional knowledge, although it can also cost them more money. Just keep in mind to purchase or choose the parts with a high-quality rate that will surely give your tuned-up Glock its best performance ever.
