Why the Best Holster for Glock 43X MOS with Radian Weapons Compensator Is Necessary
I’ve found that once I added a Radian Weapons compensator to my Glock 43X MOS, a regular holster just wasn’t enough anymore. The extra length and altered profile meant my pistol no longer fit the same way, and I needed a holster that matched the new setup exactly. A proper holster gives me a secure fit, better retention, and peace of mind knowing my firearm stays in place whether I’m moving, sitting, or carrying all day.
My biggest concern is safety and comfort. With a compensator attached, the muzzle end changes, and using the wrong holster can lead to poor draw, unnecessary wear, or even unsafe contact with the trigger area. The best holster helps me carry confidently because it protects the firearm, covers critical parts properly, and makes my draw smooth and consistent when I need it.
I also appreciate how the right holster improves everyday carry. My Glock 43X MOS with a compensator is easier to conceal and more comfortable when the holster is designed for that exact combination. For me, that makes a huge difference in daily use, because a holster isn
My Buying Guides on Best Holster For Glock 43 Xmos With Radian Weapons Compensator
When I started looking for the best holster for a Glock 43X MOS with a Radian Weapons compensator, I quickly realized that not every holster labeled “Glock 43X” would actually fit my setup. The compensator changes the overall length of the pistol, so I had to pay close attention to holster compatibility, retention, comfort, and carry style.
#1. I Looked for Compensator Compatibility First
My first priority was making sure the holster was cut long enough to accept the Radian Weapons compensator. A standard Glock 43X holster usually stops at the muzzle, but my setup extends beyond that point. If I chose the wrong holster, the compensator would not seat properly, or it could rub, bind, or print awkwardly.
What I checked:
- Open-ended holster design
- Compatibility with threaded barrels and compensators
- Clearance for the compensator’s width and shape
- No interference with the front sight or muzzle device
#2. I Chose the Right Carry Style for My Needs
I found that the best holster depends heavily on how I plan to carry.
##Inside the Waistband (IWB)
For concealed carry, IWB was my top choice. It hides the pistol better, especially with the slightly longer compensator setup. I looked for a slim holster with a comfortable sweat guard and adjustable cant.
##Appendix Carry
If I wanted fast access and deep concealment, appendix carry worked well for me. I made sure the holster had a smooth mouth opening, strong retention, and enough space to accommodate the compensator without digging into me.
##Outside the Waistband (OWB)
For range use or open carry, OWB was easier and more comfortable. I preferred a holster with a secure locking system and enough coverage to protect the compensator.
#3. I Paid Attention to Retention and Security
Because I carry a firearm, retention matters a lot to me. I wanted a holster that held my Glock 43X MOS firmly, even with the added compensator.
I looked for:
- Adjustable retention screws
- Audible “click” when holstered
- Good trigger guard coverage
- A rigid shell that keeps its shape
I avoided overly soft holsters because they can collapse and make reholstering unsafe.
#4. I Preferred Kydex for a Better Fit
In my experience, Kydex holsters were the most reliable choice for this setup. They offered:
- Better retention
- More consistent draw
- Better fit around the compensator
- Easier reholstering
- Better durability over time
Leather can be comfortable, but I found it less predictable with a compensator. Hybrid holsters can work, but I still preferred Kydex for consistency.
#5. I Checked for Optics and MOS Compatibility
Since my Glock 43X MOS may have an optic mounted, I made sure the holster worked with the slide cut and sight setup. Some holsters are made for plain slides only, while others are optic-ready.
I looked for:
- MOS-compatible holster design
- Red dot sight clearance
- Suppressor-height sight compatibility if needed
- No pressure on the optic housing
#6. I Made Comfort a Big Priority
A holster can be technically perfect, but if it feels awful, I won’t wear it consistently. For me, comfort was essential for daily carry.
I considered:
- Rounded edges to reduce rubbing
- Adjustable ride height
- Adjustable cant angle
- A sweat guard to protect my skin
- Clips or loops that stay secure without digging in
The compensator adds length, so I also made sure the holster didn’t poke or press uncomfortably when I sat down.
#7. I Wanted Easy Concealment
I knew that a compensator could make concealment a little more challenging, so I looked for a holster that helped reduce printing.
What helped me most:
- Slim profile
- Tight fit against the body
- Adjustable ride height
- Good belt clip placement
- Dark, low-profile design
I also paid attention to my clothing choice, because even the best holster needs the right cover garment.
#8. I Made Sure the Holster Was Built for Daily Use
I wanted something durable enough for everyday carry, not just occasional range trips. My holster needed to hold up to repeated draws, reholstering, sweat, and movement.
I checked for:
- Thick, quality Kydex
- Reinforced clips
- Strong hardware
- Rust-resistant screws
- Reliable build quality from a trusted maker
#9. I Considered My Draw Speed and Reholstering
A good holster should let me draw smoothly and reholster safely. I tested how easily my Glock
Final Thoughts
In my experience, the best holster for a Glock 43X MOS with a Radian Weapons compensator is one that offers a precise fit, solid retention, and enough clearance for the added length. I’d focus on a holster specifically designed to accommodate both the MOS setup and the compensator, so you don’t sacrifice comfort or draw reliability. My key takeaway is that the right holster should balance concealability, safety, and easy everyday carry without any unnecessary compromise.
