Step by Step Instructions

Learn how to build a custom DIY Kydex holster with our step-by-step instructions. Perfect your creation with preparation, molding, finishing, and final adjustments.

Step 1: Preparing the Gun

First, tape up the gun to protect it and fill in any grooves where the Kydex might accidentally press in and trap the gun. Pay special attention to areas like the trigger guard and ejection port.

Masking Tape: Wrap it over controls and around triggers to avoid pressing the Kydex into hard-to-remove shapes.
Popsicle Sticks: Use these to make standoffs in areas where the shape needs to remain open, like the ejection port and light channels.

Step 2: Making Channels

If your gun has a light or other attachments that need clearance:

Metal Strips and Popsicle Sticks: Attach these to the taped gun to ensure the Kydex molds in a way that leaves these areas clear. Tape these parts securely in place.

Step 3: Preparing and Cutting the Kydex

Before heating, you need to cut the Kydex to a manageable size.

Box Cutter: Carefully measure the size you need, and cut the Kydex a little larger than required. Excess can be trimmed later, but it's difficult to add more material if you cut too small.

Step 4: Heating the Kydex

Preheat your oven to around 360°F. Heat the Kydex for about 60-90 seconds until it becomes pliable.

Pro Tip: While the Kydex heats, ensure your press is ready with all clamps and vises in place.

Step 5: Molding the Kydex

Once heated, remove the Kydex with gloves to avoid burns and immediately place it around your prepared gun.

Press: Clamp the Kydex securely, ensuring it molds tightly but not overly snugly around the standoffs and channels you've prepared.
Vise and Clamps: Use these to hold the press together tightly while the Kydex cools and hardens, usually taking about 5-10 minutes.

Step 6: Trimming and Finishing

After the Kydex has cooled:

Pencil or Sharpie: Mark the lines where you need to trim away excess material. Ensure you leave enough material around the edges to protect both the gun and your body.
Cut: Use your box cutter carefully to trim along the marked lines. Sand any rough edges to avoid discomfort and look neat.

Step 7: Attachment Points and Fine-tuning

Drill holes for the clips and any other attachment points.

Chicago Style Screws: Make sure you're using high-quality screws. Installing these will allow you to adjust the retention and ensure your holster sits comfortably at your desired height.
Drill Angles: Drill slightly angled holes if you need adjustable positioning for the clip.

Step 8: Final Adjustments and Testing

Finally, test the fit of your gun in the holster. If areas feel too snug or loose:

Heat Gun: Apply localized heat and make fine adjustments, such as pinching the Kydex by hand if needed.

Customization Ideas for Your DIY Kydex Holster

Customizing your DIY Kydex holster can be a fun and rewarding process. It allows you to make a holster that is uniquely yours, tailored to your style and needs. Here are some ideas to inspire your customization journey:

Choose Your Color or Pattern: Kydex sheets come in a variety of colors and patterns. For a traditional look, you can select a classic black or coyote brown, or opt for something more vibrant, like neon green or pink. Camouflage patterns are also popular among outdoor enthusiasts.
Add Textures for Grip: Applying textures to your Kydex can enhance the grip and make your holster more secure. You can use tools to press patterns into the warm Kydex before it hardens, making a custom texture that feels good in your hand.
Personalize with Engravings: If you have access to an engraving tool, consider adding a personal touch to your holster with your initials, a meaningful date, or a simple design. This not only adds personality but also makes your holster easily identifiable.
Attach Custom Clips or Loops: The type of clips or loops you choose for your holster can significantly affect its carry. Experiment with different styles to find what works best for you. Some prefer the stability of loops, while others like the convenience of quick clips.
Experiment with Molding Techniques: Kydex is a thermoplastic, which means you can mold it into various shapes. Try different molding techniques to make unique contours and fits for your firearm. This can also affect the retention and draw speed of your holster.
Incorporate a Light or Laser Cutout: If you use a light or laser attachment on your firearm, you can customize your holster to accommodate it. This requires precise cutting and molding to ensure a snug fit while still allowing for quick access.
Use Decorative Rivets or Eyelets: The rivets or eyelets used to assemble your holster can also be a decorative element. Choose from different metals or colored finishes to add a subtle flair to your design.
Consider Comfort Modifications: Think about where the holster will sit on your body and make adjustments for comfort. This might include smoothing edges, adding padding, or altering the shape to fit better against your body.

Plan your design carefully and test modifications for enhanced look and function. Prioritize safety and enjoy making your Kydex holster unique.

Troubleshooting Common Issues

When crafting your own Kydex holster, you might encounter a few hiccups along the way. Here's a straightforward guide to solving some of the most common problems you may face:

Kydex Isn't Molding Properly

Solution: Ensure the Kydex is heated evenly to the right temperature, typically around 300-350°F (149-177°C). Use an oven thermometer to check the temperature if you're unsure.

Holster Is Too Tight or Too Loose

Solution: Adjust the retention by reheating the Kydex around the retention points and pressing it more firmly or gently around the firearm. Practice makes perfect, so don't be afraid to try a few times.

Air Bubbles or Imperfections in the Kydex

Solution: Air bubbles can form if the Kydex is overheated. Heat the material slowly and evenly, and use a roller or similar tool to smooth out any bubbles or imperfections before it cools.

Rough Edges or Sharp Corners

Solution: After cutting and molding your holster, use fine-grit sandpaper to smooth any rough edges. This will make the holster more comfortable to wear and prevent it from snagging on clothing.

Holster Doesn't Fit the Belt Properly

Solution: Check the size of your belt loops or clips and compare them to your belt's width. You may need to resize or replace them to ensure a secure fit.

Difficulty Drawing the Firearm Quickly

Solution: Work on the draw angle and the placement of the holster on your body. Adjusting these can significantly improve your draw speed.

Holster Is Not Aesthetically Pleasing

Solution: Consider redoing the finish on your holster. A heat gun can be used to give a polished look, and edge paint can add a professional touch.

Making a DIY Kydex holster takes patience and practice. Don't get discouraged by mistakes. You'll soon make a functional, personalized holster.
