Deadly Customs Glock Signature Light-Bearing Kydex for SureFire X200 / X300

Serious shooters and tactical professionals know that your holster must match the reliability of your weapon system. The Deadly Customs Glock Signature Light-Bearing Kydex for SureFire X200 / X300 holster is engineered precisely for that purpose.
Designed around the SureFire X200 / X300 and their compatible clones such as the Nurpol X200 / X300, this holster offers rugged dependability, repeatable retention, and a refined fit suitable for both duty and range environments.

The Deadly Customs Glock Signature Light-Bearing Kydex for SureFire X200 / X300 was developed and manufactured entirely in the United Kingdom from genuine 2 mm P1 Kydex, this holster reflects Deadly Customs’ commitment to producing professional-grade gear that performs under stress. Each unit is formed on an in-house mould, then finished and tested by hand, ensuring that every holster leaving our workshop meets strict tolerance and functionality standards.

Mission-Driven Design Philosophy

When we designed the Deadly Customs Glock Signature Light-Bearing Kydex for SureFire X200 / X300 holster, we aimed to create a light-bearing holster that could serve multiple weapons, function seamlessly in demanding conditions, and still maintain a low-profile, streamlined appearance.
By using the attached torch as the retention interface, operators who run the same SureFire-pattern light on multiple pistols can rely on a single holster platform for all — saving time, weight, and cost while maintaining consistent muscle memory.

The Signature Series also takes inspiration from our popular DC-4 SureFire Holster, retaining its proven functionality but refining the lines for a more aggressive and compact aesthetic. The slightly higher guard accommodates larger pistols like the FNX while protecting optics and slide finishes from abrasion.

Construction and Materials — Engineered for Endurance

At the core of every Deadly Customs holster lies our chosen material: 2 mm P1 Kydex. This thermoformed polymer is favoured by professionals worldwide for its combination of rigidity, heat stability, and impact resistance.
Unlike cheaper plastics or injection-moulded variants, Kydex retains its structural integrity across extreme temperature ranges and heavy use.

Every Glock Signature Series holster is:

• Precision-formed from in-house weapon and torch scans to guarantee a consistent, exact fit.

• Edge-finished by hand to eliminate sharp corners and ensure comfort during long shifts or training sessions.

• Riveted and fastened with corrosion-resistant hardware rated for long-term outdoor exposure.

• Quality-controlled at multiple stages — forming, trimming, fitting, and retention testing — before being approved for dispatch.

This process yields a holster capable of withstanding constant draws, rough handling, and exposure to dirt, sweat, and weather without compromising performance.

Compatibility — Works With Over 150 Pistols

The Deadly Customs DC-4-pattern architecture behind the Signature Series is one of the most extensively tested light-bearing Kydex designs on the market.
After trials with more than 150 pistols, the Signature Series was confirmed compatible with nearly every major Glock variant and a wide array of full-frame sidearms.

Only four models were found incompatible due to extreme dimensions:

1. Full-size Desert Eagle

2. ASG USW

3. MK23

4. Hudson

For the professional end user, that means exceptional cross-platform flexibility.
Whether you’re running a Glock 17, 19, 22, 34, or another railed model fitted with a SureFire X200/X300 or a compatible clone, the Signature Holster delivers a consistent fit and secure lock-up.

Light-Bearing Retention System

Unlike conventional moulded holsters that capture the trigger guard directly, the Signature Series secures the weapon by locking onto the attached torch body.
This retention method has several operational advantages:

• Cross-compatibility: the same holster can be used for multiple pistols equipped with the same light model.

• Enhanced clearance: prevents pressure on the slide or frame, reducing cosmetic wear.

• Positive indexing: audible and tactile feedback when holstering, so you know the weapon is secure.

• Stable draw cycle: consistent release tension regardless of slide modifications or optics.

Because the light itself provides the locking surface, this system also prevents wobble that can occur with generic “one-size” holsters.
Important: the torch must be attached for the holster to function correctly — without it, the pistol will not be retained. For non-light configurations, Deadly Customs recommends the DC-1 Series holsters.

Adjustability and Ergonomics

Every Signature Glock Holster features two independent retention points, allowing the shooter to fine-tune draw resistance to exact preference.
Use a standard screwdriver to make small incremental adjustments; each turn meaningfully alters tension. Once dialled in, apply a small amount of Loctite Blue or a dab of super glue to secure your settings against vibration.

The higher guard and contoured body provide improved contact on full-frame pistols and add protection for optics and safeties.
When combined with the RMR cut, the holster easily accommodates red-dot-equipped Glocks without interference during draw or re-holstering.

Operators will appreciate the overall slim profile that hugs close to the body, reducing printing and snag potential during dynamic movement or vehicle operations.

Optic, Sight, and Barrel Compatibility

Modern fighting pistols often feature threaded barrels, suppressor-height sights, or miniature red-dot optics.
The Signature Series holster was engineered with all of these in mind:

• RMR Cut: allows use of most slide-mounted optics (Trijicon RMR, Holosun 507C, etc.).

• Suppressor-Height Sight Channel: taller sight posts track cleanly through the draw path without drag.

• Threaded Barrel Clearance: the open muzzle design ensures compatibility with extended or threaded barrels, compensators, or muzzle devices.

This adaptability ensures that professionals running custom or upgraded sidearms can maintain full functionality without compromise.

Mounting Systems and QLS Compatibility

Versatility extends to how you mount it. The Glock Signature Series interfaces with most professional 3-screw platform systems, including:

• Safariland

• Blackhawk

• FMA

• G-Code and G-Code RTI

• Blade-Tech

If you select the QLS (Quick Locking System) option at purchase, the holster ships with the male QLS fork only.
For a full detachable setup, add the corresponding female QLS receiver plate from our holster-mount section.
This modular approach lets you move the holster quickly between duty belt, leg rig, or chest-mount platforms while maintaining identical angle and draw consistency.

Maintenance and Care Guidelines

A professional holster deserves professional care:

1. Routine cleaning: wipe down interior and exterior surfaces with mild soap and water to remove carbon and debris.

2. Hardware check: periodically tighten retention screws and mounting bolts.

3. Heat awareness: avoid storing in hot vehicles or direct sunlight for prolonged periods.

4. Inspection: check for cracks or deformities after heavy impacts; replace hardware if corrosion appears.

With basic maintenance, your Kydex holster will deliver years of dependable service in both training and operational environments.

Professional Testing and Quality Assurance

Every Signature Series holster undergoes a multi-stage verification process:

• Form and Fit Check — confirming precise interface with the SureFire light body.

• Retention Cycle Testing — repeated draw/holster actions to ensure consistency.

• Environmental Durability — exposure to moisture, dirt, and abrasion testing.

• Visual & Finish Inspection — ensuring edges are smooth and hardware is secure.

Only holsters that pass all stages are packaged and approved for sale. This commitment to quality is what sets Deadly Customs apart from mass-produced imports.
