Glock 43X ARC Holster Compatibility with the Herrington Arms ZERO Compensator

Glock 43X + ZERO Comp + ARC Holster: Yes, They Work Together
If you’re running a Glock 43X with a Herrington Arms ZERO compensator, holster compatibility is usually the first concern. Many IWB holsters rely on the slide or trigger guard geometry for retention, which can cause problems once a compensator is added.
Thanks to its weapon-light-based retention system, the ARC holster remains fully compatible with the Herrington Arms ZERO Comp—even though the compensator extends past the factory slide length.
Why Light-Based Retention Changes Everything
Most standard Glock 43X holsters clamp around the slide or trigger guard.
That’s why compensators often cause poor fit, binding, or unsafe retention.
The Tulster ARC holster indexes retention on the weapon light, not the slide or muzzle. This design means:
- Retention is locked onto the light body
- Overall slide length becomes irrelevant
- Muzzle devices like the ZERO Comp do not affect fit
As long as you’re using a compatible weapon light (such as the TLR-7 sub), the ARC holster doesn’t care whether your Glock 43X is running:
- A threaded barrel
- A compensator
- A factory-length slide
And since this ARC is also compatible with the Glock 48, the length is perfect for a Glock 43X + compensator.
Why the Herrington Arms ZERO Comp Works with the ARC
The Herrington Arms ZERO compensator adds performance without changing the critical dimensions that matter to the ARC holster’s retention system.
Key reasons for compatibility:
- The ZERO comp sits forward of the slide
- It does not interfere with the weapon light
- It does not alter trigger guard geometry
- ARC retention does not clamp the slide or muzzle
Because the ARC holster leaves the muzzle area open and retains exclusively on the light, the ZERO compensator clears the holster cleanly without contact or resistance.
Concealed Carry Benefits of This Setup
Pairing the Glock 43X + ZERO Comp + ARC holster gives you:
- Reduced muzzle rise and flatter shooting
- Secure, repeatable retention
- Clean draws with no comp drag
- No need for a “comp-specific” holster
- No loss of safety or retention integrity
This makes the ARC an ideal solution for shooters who want to upgrade performance without sacrificing everyday carry reliability.
What to Verify Before Carrying
To ensure proper fit, confirm the following:
- You’re using a supported weapon light for the ARC holster
- The weapon light is tightened down
- The compensator does not exceed the width of the slide
If those boxes are checked, the ARC holster will function exactly as intended—even with the ZERO Comp installed.
Final Verdict
The Glock 43X is fully compatible with the Tulster ARC holster and Herrington Arms ZERO compensator.
The design choice eliminates the most common holster issues associated with compensators and allows shooters to confidently run performance upgrades without changing their carry system.
If you’re looking to run a compensated Glock 43X without sacrificing concealment, security, or consistency, this setup delivers.
