Best Holster for Glock 43X MOS: How to Carry an Optics-Ready 43X Without Printing
Share
The Glock 43X MOS is one of those pistols that makes sense before you ever fire a round.
It is slim. It has enough grip to run better than a tiny pocket gun. It is optics-ready. It fits the daily carry lane without feeling like you are trying to hide a brick under your shirt.
But the MOS part changes the holster conversation.
A Glock 43X MOS holster has to do more than hold the pistol. It has to clear the optic, protect the trigger guard, manage the grip, and carry comfortably enough that you do not start leaving the gun at home. The wrong holster makes even a slim pistol print, shift, dig, or draw poorly.
That is where the setup matters.
The Glock 43X MOS is a good carry gun. A proper holster turns it into a carry system.

Why the Glock 43X MOS Needs the Right Holster
The Glock 43X MOS is not just a standard slimline carry pistol. It is built for optics, and that means your holster has to account for the red dot or optic cut.
A standard holster that does not clear the optic can cause fit problems. It may block the optic, interfere with the draw, or fail to seat the pistol properly. That is not something to gamble with.
The 43X MOS also has a longer grip than the Glock 43, which is good for control but can increase printing. That means the holster needs to help tuck the grip back into the body.
A Glock 43X MOS holster should solve three problems:
Keep the pistol secure
Keep the trigger protected
Keep the gun concealed
If it does not do all three, it is not the right holster.
Glock 43X MOS and Printing
Printing usually comes from the grip, not the slide.
The Glock 43X MOS is slim, but the grip still has enough length to show through clothing if the holster is poorly set up. A good holster helps manage that grip by controlling ride height, angle, and how tightly the pistol sits against the body.
Appendix carriers often notice printing when the grip kicks outward. Strong-side carriers may see printing when the grip pushes through the shirt during movement, bending, or reaching.
You do not fix that by buying a smaller gun every time.
Sometimes you fix it with a better holster setup.
Appendix Carry Glock 43X MOS
Appendix carry works well with the Glock 43X MOS because the pistol is slim and short enough to carry in front of the body without feeling oversized.
The upside is access. Appendix carry gives many shooters a fast, natural draw and good control over the pistol throughout the day.
The downside is comfort and setup sensitivity. Ride height, belt tension, holster angle, and grip tuck matter. A small change can be the difference between a pistol that disappears and one that pokes you every time you sit down.
For appendix carry, look for:
Full trigger guard coverage
Good retention
Optic clearance
A stable clip
A profile that helps tuck the grip
A ride height that allows a clean draw
The Glock 43X MOS is a solid appendix carry gun when the holster is built for the job.
Strong-Side Carry Glock 43X MOS
Strong-side IWB carry, often around 3 to 4 o’clock, is still a good fit for the Glock 43X MOS.
This position can be more comfortable for some carriers, especially when sitting or driving. It can also work better for people who do not like carrying in front of the hips.
The tradeoff is printing. Strong-side carry can make the grip print when you bend, reach, or wear tighter clothing. Cant becomes more important here. A slight forward cant can help the grip follow the body better.
A strong-side Glock 43X MOS holster should still give you a clean draw, strong retention, and full trigger protection.
Best Glock 43X MOS Holster Features
A Glock 43X MOS holster should be simple, but not cheap in the wrong places.
The best features are the ones that make daily carry safer and more consistent.
Optic Compatibility
This is the MOS requirement.
If you carry a red dot, the holster must clear it. Do not assume an older Glock 43X holster will work just because the pistol fits the shell. Confirm the holster supports optics.
Full Trigger Guard Coverage
This is not optional.
A Glock 43X MOS holster should fully cover the trigger guard so clothing, fingers, cords, and debris cannot contact the trigger while the gun is holstered.
Secure Retention
The holster should hold the pistol firmly during normal movement.
Walking, sitting, bending, driving, and getting in and out of vehicles should not make the pistol shift or work loose. Retention should feel secure without making the draw ugly.
Comfortable IWB Profile
The Glock 43X MOS is built for daily carry, so the holster needs to live there too.
A holster that digs, shifts, or pinches will eventually get left behind. Comfort matters because consistency matters.
Good Grip Tuck
The grip is what prints.
A holster that helps rotate or tuck the grip inward can make a noticeable difference, especially with the 43X grip length.
