How To Make Kydex Holster?


Why can’t you find a suitable holster for your gun from any store? You may want to check your gun first whether it is a popular product in the market. If it is not, that explains the reason. Most companies only manufacture items for the majority.

In this case, don’t worry if you’re one of the minority. Keep scrolling down this article to learn how to make Kydex holster all by yourself.

What Is A Kydex?

Kydex is a line of thermoplastic acrylic-polyvinyl chloride. It was first used as a material for aircraft interiors in the 1960s by Rohm and Haas. That’s when people realized the capacity of this kind of plastic.

Its composition is a combination of the rigid nature of acrylic and the toughness and resistance of the PVC. We could turn sheets into various shapes by heating and framing and use them for multiple purposes such as holsters, knife sheaths, safety helmets, and door liners.
Kydex becomes a favorite one when it comes to a substance to make holsters.

Why Do You Need A Kydex Holster?

There are two ideal options for material in making holsters: leather and Kydex. Honestly, it’s a tie to compare these two. That’s really up to your personal opinion. But to choose one to self-make at home, this material is recommended since leather requires much meticulousness.

As mentioned above, we could mold sheets into a massive range of shapes at high temperatures. It helps draw and re-holster your gun quickly and easily. Once the sheets cool down, their shapes will last perfectly well, even for a long time.

Another advantage of a homemade Kydex holster is its retention. No matter how hard you impact your gun, it will firmly remain in the same place. Due to their plastic-like structure, holsters are lightweight for daily use. Also, they can prevent water, scratching, and other external causes.

From an economic perspective, this type of material is cheaper than leather. You can consider it as the least costly material for making holsters in the market at present.

How To Make Kydex Holster

Making Kydex holsters is a pretty easy process. Yet, let’s read this instruction below to picture it generally before getting to work. Understanding the guideline first will help the process be smoother and simpler.

Materials And Tools

Make sure that these items are in your house:

  • Kydex
  • Oven
  • Heat gun
  • A Press
  • Rivets
  • Chicago screws
  • Drill
  • A pencil

Preparation Of Sheet

This first step requires the right size of the Kydex you need. Put the gun on the plastic and start scoring the main shape of the gun with a pencil. The measurement should have some extra space instead of the exact size of the gun.

Then cut out the main square containing the drawing and place it in the oven. You can preheat the oven to 200 or 250 degrees. This low temperature reduces the possibility of the edges curling up and makes the material easier to control.

Forming The Kydex

Your plastic is ready for the next step when it gets enough heat and pliability. If so, take it out of the oven carefully. From this stage of the process, we suggest starting using heat-resistant gloves.

On the bottom layer of the press, put down the heated sheet and place your gun on top of it. Then wrap the material around the gun like a taco. Let the top part of the press stay up on the wrapped gun before locking it into place and rest for around 10 minutes.

After that long, you can take the material off the press and check your result. If it doesn’t look like your expectation the first time, you can reheat the Kydex and start all over again. Otherwise, remove the gun from the material.

Cut Out The Kydex Mold

The following step is to mold this material. Start drawing the spare part you intend to trim off and marking spots to put your rivets to keep the material fixed. Cut off the edges by a Dremmel.

Use any tools available at your home to trim and sand the edges. Any unnecessary details should be removed for the most compact and smooth result. At the marked spots, drill holes and install your rivets.

Checking Your Holster

Before moving to this point, clean up your holster fragments to avoid them from breaking your gun. When your gun is clean, it’s time to test it.By sliding your gun in and out of the holster, you will see whether it is well-matching the gun.

If it doesn’t go well, you can easily adjust unfitting areas to perfect the retention. Heating those wanted spots up slowly and using your hands to press from the outside until you’re satisfied with the result.

Adding A Belt Attachment

A bell attachment requires thicker material to make. Put the material into a strip equally. Make holes on the belt clip and make sure they will match with the rivets on the holster. In order to get the same form as the holster, you need to soften the strip by using a heat gun and mold it into place once.

Then mark where you intend to bend the clip and warm that area up to curl it easily. Let it cool down. Measuring the clip as your normal size belt and removing the excess. Use Chicago screws to attach the clip to the holster. Your holster is finally ready to use.


Above is all the information on how to make Kydex holster. We’re sure that it’s not a complicated process, and anyone who wants to own a custom holster can absolutely try some times.

It might not be as you supposed after the first time but feel comfortable fixing it until you’re satisfied since this material is super easy to mold. Take your time, enjoy the process and achieve a good holster.
