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 standard holster just didn’t feel right anymore. The extra length and different front profile meant my pistol no longer fit the same way, and that can affect both comfort and safety. A proper holster gives me a secure fit, so I know my firearm stays in place whether I’m walking, sitting, or moving quickly.

My biggest reason for choosing the best holster is confidence. I want reliable retention, smooth draw, and safe reholstering every time. With a compensator attached, I need a holster designed to accommodate the added dimensions without rubbing, snagging, or forcing the gun into place. That makes everyday carry much more practical and less frustrating.

I also care about comfort and concealment. A well-made holster helps me carry my Glock 43X MOS more discreetly while keeping the compensator from printing or creating pressure points. For me, the right holster is not just an accessory—it’s a necessary part of carrying safely, comfortably, and effectively.

My Buying Guides on Best Holster For Glock 43 Xmos With Radian Weapons Compensator

When I started looking for the best holster for my 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 and shape at the muzzle, so I had to pay close attention to compatibility, retention, comfort, and concealment. Here’s the buying guide I wish I had when I began.

1. Make Sure the Holster Supports a Compensator

The first thing I checked was whether the holster was made to fit a Glock 43X MOS with a compensator. A standard 43X holster usually stops at the muzzle, and if it’s too tight or closed at the bottom, it won’t work with the extra length of the Radian comp.

What I looked for:

  • Open-ended or extended-bottom holsters
  • Explicit compensator compatibility
  • Clearance for threaded barrels and muzzle devices

If a holster doesn’t mention compensators, I assume it probably won’t fit properly.

2. Choose the Right Holster Type for My Carry Style

I had to decide how I wanted to carry before choosing a holster. My carry style made a big difference in comfort and concealment.

Common options I considered:

  • IWB (Inside the Waistband): Best for concealment, but comfort matters a lot with a compensator.
  • OWB (Outside the Waistband): Easier to draw and often more comfortable, but harder to conceal.
  • Appendix Carry: Popular for fast access, though I needed a holster with excellent trigger protection and comfort.
  • Side Carry / 3–4 O’Clock: More traditional and sometimes easier to wear for longer periods.

For me, the best choice depended on whether I wanted maximum concealment or maximum comfort.

3. Look for a Proper Muzzle Opening

Because my Glock has a compensator, the muzzle area was one of the most important things to verify. I wanted a holster with enough room so the compensator wouldn’t rub, snag, or force the gun in at an angle.

A good holster should:

  • Allow smooth reholstering
  • Not press against the compensator
  • Keep the firearm seated securely without damaging the finish

If the muzzle end is too tight, I found it can make drawing and holstering frustrating.

4. Prioritize Retention and Trigger Protection

Retention is non-negotiable for me. I want my firearm to stay secure during movement, but I also want a clean, consistent draw. Just as important, the holster must fully cover the trigger guard.

What I prefer:

  • Adjustable retention if possible
  • Full trigger guard coverage
  • A rigid holster body that doesn’t collapse

Kydex holsters usually gave me the best balance of security and reliability.

5. Consider Comfort for Daily Carry

A holster can be technically perfect and still be miserable to wear. Since I planned to carry often, comfort mattered a lot.

Comfort features I looked for:

  • Smooth edges and rounded corners
  • Sweat guard to protect my body and firearm
  • Claw or wing attachment for better concealment
  • Adjustable ride height and cant

If I can’t wear the holster for several hours without irritation, I know I won’t use it consistently.

6. Check Compatibility with Glock 43X MOS Features

Since my pistol is the MOS version, I made sure the holster worked with the slide profile and any optic setup I might add. Some holsters are cut for optics, while others are not.

I checked for:

  • Optic cut if I use a red dot
  • Clearance for slide-mounted accessories
  • Proper fit around the MOS slide dimensions

Even if I don’t run an optic right away, I like having the option.

7. Decide Between Kydex, Leather, or Hybrid

I compared materials before buying, and each one had its pros and cons.

Kydex:

  • Best for retention and durability
  • Great for consistent draw
  • Usually my top choice for a compensator setup

Leather:

  • More comfortable in some cases
  • Can wear in over time
  • Less ideal for consistent retention and moisture resistance

Hybrid:

  • Combines comfort and rigidity
  • Can be bulky
  • Quality varies a lot

For my Glock 43X MOS with a compensator, I leaned toward Kydex because it gave me the most confidence.

8. Make Sure It Conceals Well

Final Thoughts

In my experience, the best holster for a Glock 43X MOS with a Radian Weapons compensator is one that offers a secure fit, proper trigger protection, and enough clearance for the comp. I always look for a holster designed specifically for compensated setups so I can carry comfortably without sacrificing retention or safety. My main takeaway is that the right holster should balance everyday concealment with reliable performance, especially with the added length of the compensator.
