All The Parts You Will Need To Make a Custom Pistol

To make a custom pistol you will need about twenty parts for the lower and upper receiver. You will also need the right tools to assemble all the parts.

Building custom pistols is fascinating and many people, especially collectors, are passionate about it.

Building your custom gun can be quite difficult. The most important issue is the parts of the gun. But it is not a wise decision to make a custom pistol if you are a first-timer or have no prior experience with firearms. Take these steps only if you have proper knowledge about each weapon component. Additionally, there are laws that deal specifically with firearm construction. For this to be legal, you will likely need to look at an 80% lower project or go through an FFL to purchase a serialized lower receiver.

As with any other firearm article on the site, we encourage you to know the laws that affect you.

If you are willing to build your custom gun, then we suggest you try to build a custom Glock. They are the most common pistols out there, and every custom weapon builder hones their skill by building a Glock.

The Parts Required To Make A Custom Pistol

To create custom pistols you need experience. You can always try creating dummy guns to understand how real custom guns can be created.

Toy guns like gel blasters can also be a good alternative. They do not have nearly as many parts but some of the newer models look similar to actual guns. You can even purchase upgrade kits or accessories and assemble them by putting the pieces together.

If you want, you can visit gbb pistol parts Australia to purchase gel blasters that look like real guns and some accessories to have a slight idea about how guns can be assembled.

Now, as for making a real custom pistol there are several parts. To make things simpler, we divide these parts into two sections. The Lower Receiver, and the Upper Receiver.

The Lower Receiver

To make a custom pistol, you will need to purchase a lower receiver.
Depending on the platform, many of the items below come included with the Lower you purchase.

Many manufacturers will see all of the individual pieces you need to build out a Glock Polymer lower as a parts kit.

1. Trigger Guard To Prevent Unwanted Gunfire

The trigger guard is a protective loop placed around the trigger of your gun. It prevents unnecessary pressure applied to the trigger that might lead to unwanted gunshots.

2. Trigger Housing With Ejector To Align Your Trigger

This component houses your trigger. If you are building a Glock, the ejector will come alongside the trigger housing.

3. Trigger Connector To Firmly Hold Triggers

This component places resistance in your trigger. Otherwise, the trigger would be loose and even at the slightest fling, the gun might fire a bullet. The resistance you feel when pulling the trigger is caused by this component.

4. Magazine Catch To Hold The Magazine

This component holds the magazine of your gun. They are different for left-handed and right-handed people. So pick the one depending on your strong hand.

5. Pin Set To Keep Things In Place

These pins keep the gun secured. The pins hold everything in place so that your trigger, locking block, and trigger box do not come flying apart when you fire the gun.

6. Locking Block For Smooth Barrel Movement

It makes sure the slider and the barrel of the gun move securely without coming loose.

7. Magazine Catch Spring To Tightly Lock The Magazine

Just as trigger connectors make sure the trigger does not become loose, the magazine catch spring ensures that the magazine does not get loose and come off.

8. Trigger With Bar

This is the actual trigger you press when firing your gun. The gun will not be complete without this component.

9. Slide Stop

Slide stop, also known as a slide lock, allows you to reload your handgun. It visually pulls the slide backward when you expand all ammo. 

10. Slide Lock Spring

This spring allows smooth movement of the slide lock. It puts pressure on the slide lock and keeps it aligned.

11. Slide Stop Lever

The slide stop lever determines how easily the slide lock can slide to the rear. The easier it is, the more smoothly you can pull the slide lock.

12. Pistol Grip

And the last component of the lower receiver is the pistol grip. It is placed around the magazine cache, you can choose any grip depending on your personal preference.

The Upper Receiver

1. Barrel

This is the place from where a bullet travels before leaving the gun and hitting the target.

2. Spring Load-bearing

There are two types of spring load bearings. The Load Chamber Indicator, and the non-Load Chamber Indicator. It provides tension on the extractor so that it works properly

3. Extractor With Chamber Indicator

So what are extractors? After you fire a round, the extractor extracts a round from the chamber. The chamber indicator lets you know if there is a round in the chamber.

4. Extractor Depressor Plunger and Spring

This component absorbs the force from the extractor spring and transmits it. The transmission allows the extractor to rotate and allows the extractor to firmly hold the rim of your cartridge.

5. Firing Pin and Spring

The firing pin is the valuable component that makes your gunfire a shot. Without the firing pin, no matter how much you pull the trigger, your pistol will not fire.

6. Firing Pin Channel Liner

This part is unique to Glocks and cannot be found on other pistols like the Beretta or 1911. This chamber liner helps prevent any wear in the weapon slider because wearing is a very common occurrence in Glocks.

7. Slide Cover Plate

Almost all slide cover plates in Glocks are custom-made. The purpose of this component is to hold the firing pin and extractor depressor plunger together.

8. Front And Rear Sights

Now, if you want to gain the perfect accuracy while shooting, you will need Glock sights. You can either keep the traditional iron sights for Glocks or get something more unique like tritium sights.

9. Recoil Spring Assembly

This helps absorb the shock after you fire the gun. It prevents muzzle flip, which slightly reduces your gun from rising.  This allows you to maintain better stability and accuracy after you fire.

Tools Required To Make A Custom Pistol

You will need a toolkit to assemble your gun that should have the following-

  • Set of metal files
  • A rotary tool or Dremel that has a sanding drum
  • Different types of fine and coarse grit sandpapers such as 100,800 and 1200 grit
  • A nylon hammer
  • A flathead screwdriver
  • Firearm lubricants and WD-40
  • A bench vise to help you work with more precision
  • An optional power drill

Final Thoughts

Building a custom pistol is not an easy task. So, gain knowledge and experience first about the different parts, maintain safety precautions, and create a few dummy guns before building a real custom one.
