Last updated: October 17, 2026 · Written by Fuse Gunbangkok

More people are using firearms with built-in flashlights because good quality flashlights are readily available. But what follows is... Your existing holster won't fit right away. And if you're using a less commonly used flashlight model, finding a ready-made holster is virtually impossible. This article explains why these types of holsters are difficult to design, the limitations of ready-made holsters, and the custom ordering process at GUN BANGKOK.

Retention System: What are the locking points of a Kydex holster?

The heart of every Kydex holster is... Retention, or the force that holds the device in place. A standard holster without a flashlight will lock at... Trigger Guard Because it's the position with the most consistent shape and grip, the advantages are a secure lock, smooth drawing, a compact size for easy concealment, and precise control due to the fixed factory dimensions of the firearm.

When a flashlight is attached, the rules of holster design change entirely.

The flashlight replaces and obstructs the trigger guard area. The shape of the front of the trigger guard has changed, and the original pressure point can no longer create gripping force. Therefore, the holster must... The retention system has been completely redesigned and moved to lock onto the flashlight body.

Simply put: The holster doesn't grip the gun itself, but the flashlight attached to the gun.

Why do holsters with flashlight attachments have to be model-specific?

1. Same gun model, but different flashlight models = Different blocks/designs.

For example, Glock 19 The following four sets require different molds and retention points.

Each flashlight model also has different mechanisms, such as: Olight model with quick-release lever. There are raised buttons on the sides that make it easy to find the locking point. Model without raised buttons It must be locked onto the flashlight rail adapter. Streamlight TLR-6 It was the most difficult part because there was neither a lever nor a thick rail. The technician had to carefully gauge the blocking point of the holster before the flashlight to create the right amount of clamping force.

2. Retention balance must be maintained.

Too much tension makes drawing the gun difficult and causes jamming. Too little tension causes the gun to wobble in the holster, especially with a flashlight protruding below the trigger guard. Therefore, manufacturers have to experiment with multiple pressure points until they find a balance between safety and smoothness.

3. Even millimeter-level discrepancies can be felt.

Even a fraction of a millimeter's deviation can significantly change the feel of drawing the flashlight. Sometimes, even the same flashlight model but from different production batches can have slight size variations. Therefore, custom holster shops need to inspect them carefully.

Will a universal ready-made holster work?

If you're using a popular flashlight model, you might find ready-made holsters, or some brands make holsters that accommodate multiple flashlight models in one (Universal Light-Bearing Holster). The fitting will not fit 100%. The gun might wobble, move, or make noise when moved because each brand of flashlight has a different shape. If you want a holster that fits the actual equipment, it will need to be a custom-made one. Custom-made Kydex holster.

The process of manufacturing flashlight holsters using 3D scanning at GUN BANGKOK.

The traditional method involves attaching a real flashlight to a gun mold (Bluegun) and then molding it into foam. Therefore, the detail and quality depend on the craftsman's skill with each batch. GUN BANGKOK has switched to a digital process:

1. High-Resolution 3D Scan: Assemble the flashlight onto the gun model, then scan it at high resolution as a digital file (.STL).
2. Digital Mold Design: Molding blocks are designed on computer, so retention points are precise to the millimeter and the excess material that makes holsters bulky is trimmed away.
3. 3D Printing: We print a molding block for each holster. Even if you order just one, we make a new block specifically for you.
4. Consistency: Every holster made from the same block meets the same standard.

Characteristics of a good holster with a flashlight attachment.

• Positive Retention: There was a click sound. I turned the holster upside down, but the gun didn't come out.
• No rattling: The holster fits snugly against the gun and flashlight.
• Reduce friction (Minimal Wear): Avoid leaving unnecessary marks on guns and flashlights.
• Adjustable: There is a screw for the user to adjust the tightness themselves.

A good holster isn't one that's "the tightest," because if it's too tight, you might not be able to draw your gun in a real-world situation. Holsters with flashlight attachments are therefore more expensive than regular holsters, not because of higher material costs, but because of the design, retention, tolerance control, and repeated testing.
