Glock 43 Holsters
Custom Kydex Glock 43 Holsters
Most of these pages open by helping you work out which version you own. This one does not need to. Glock built the 43 as a single pistol and left it there — no optic cut was ever offered, no rail was ever moulded into the dust cover, and nothing across its production run changed a dimension the Kydex cares about.
So there is one mold, and it is cut close. On a pistol this small there is very little material to take retention from, which is exactly why a shell pressed for the slimline family in general will let it rattle.
6+1
Flush capacity
The number people trade away when they move to a 43X, and the number they come back for when it stops printing.
0.87 in
Slide width
Shared exactly with the 43X and the 48 — which is precisely why owners assume all three swap shells, and why they do not.
4.25 in
Height with magazine
Under an inch of grip sits below the trigger guard, so almost the whole pistol is inside the holster when it is seated.

There Is Only One Glock 43
Worth stating outright, because customers arrive braced to be asked: the Glock 43 has never shipped in an optic-cut or railed configuration. Glock brought the Slimline MOS models out in 2020 and named the 43X and the 48 — the 43 was not among them and has not been since. The table below is not a menu, it is the list of pistols people mistake for one.
| Pistol | What it actually is | Order this |
|---|---|---|
| Glock 43 | The single-stack six-rounder. The only configuration there is. | Glock 43 |
| Glock 43X | A taller frame holding ten rounds, on the same slide and barrel. | Glock 43X |
| Glock 48 | That taller frame again, carrying a longer slide. | Glock 48 |
| Glock 42 | Smaller again and chambered in .380. Not a 43 in any dimension. | Not currently pressed — ask us |
| Glock 43 with a magazine extension | More grip below the frame, nothing changed above it. | Glock 43 |
If you are holding the pistol and want to be certain: count the rounds the flush magazine takes. Six means a 43. Ten means you are on the wrong page and want the 43X pattern instead.
Cross-Fit
What Will Not Hold a Glock 43
The slimline Glocks share components in a pattern that looks like it should extend to holsters, and it does not. This is the part that trips people, laid out row by row.
| Firearm | Shares this shell? | What to order |
|---|---|---|
| Glock 43 with a Pearce or Taran +1 | Yes | Extensions hang below the magazine well. Your pinky notices and the Kydex never does. |
| Glock 43 wearing a grip tape wrap | Yes | Adhesive texture adds a few thousandths on the grip, which sits outside the shell entirely. |
| Glock 43X | No | Same slide on a frame nearly eight tenths of an inch taller. Drop a 43 in that shell and it sits deep and loose. |
| Glock 48 | No | Longer again at the muzzle. There is nothing for the front of the shell to close against. |
| Glock 42 | No | A .380 built on smaller tooling. We have not cut this mold yet, so tell us if you want one. |
| Glock 26 | No | Roughly a quarter-inch of extra width across the body. It will not enter the mouth of a 43 shell. |
The 43 and the 43X share a slide width and a barrel length, which is the reason this confusion exists at all. Retention on our shells comes off the trigger guard and the frame junction, and that junction sits at a completely different height on the two pistols — so the shared numbers up top never translate into a shared holster.
One pistol, one mold.
Nothing to decode here. Choose the position you carry in, the hand you draw with and the clip you want, and it goes on the bench.

No Rail, So What Actually Mounts?
Straight answer first: the Glock 43 has no accessory rail, in any year, on any model. Nothing clamps to the dust cover because there is no dust cover rail to clamp to. What people do run on this pistol attaches around the trigger guard instead, and that matters to us more than it would on a railed gun — the trigger guard is where our shell takes its retention:
- Crimson Trace Laserguard units built specifically for the 43 frame
- LaserMax and Viridian trigger-guard lasers cut for this pistol
- Streamlight TLR-6 in its Glock 42 and 43 body, light and laser together
- Nothing rail-mounted — a TLR-1, TLR-7 or X300 has no home on this gun
Red dots. There is no factory optic cut and never has been. Owners who want a dot send the slide to a machine shop, and a milled 43 is a one-off by definition — the pocket depth and the sight height come back different every time. Send us a photo of the finished slide with the optic fitted and we will cut the track to that gun rather than to an average.
Anything living on the trigger guard changes the press completely, so name it in your order and we will form around it.
Recommended Builds
Three Builds That Suit a Glock 43
Small pistols reward a shell that was cut for them and punish one that was not. These are the three we send 43 owners to most often.
Triton Series IWB Holster
$50
The straightforward one, and on a pistol this size that is a compliment. Clean retention off the trigger guard with nothing added that you would have to conceal.
Gemini Series Dual Layer IWB Holster
$70
A second material between the Kydex and your skin. The 43 rides high and tight against the body, so the backing earns its keep across a full day.
Single Mag Pouch IWB
$25
Pressed for the six-round single-stack body. Worth adding here more than on any other pistol we build for, simply because of how few rounds are in the gun.
Compare
Glock 43 vs Glock 43X vs Glock 26
The three small Glocks people cross-shop, and the numbers that decide which one disappears under a shirt.
| Glock 43 | Glock 43X | Glock 26 | |
|---|---|---|---|
| Flush capacity | 6+1 | 10+1 | 10+1 |
| Overall width | 1.06 in | Slimline, 1.10 in class | 1.30 in |
| Slide width | 0.87 in | 0.87 in | 1.00 in |
| Height with magazine | 4.25 in | 5.04 in | 4.17 in |
| Magazine stack | Single | Double, slimline | Double |
| Factory optic cut offered | No | On MOS models | On MOS models |
Choose the 43 for width and the 26 for capacity. The 43 is the flattest of the three against your body and the easiest to forget you are wearing. The 26 buys four extra rounds and pays for them in thickness, which is what you feel when you sit down. The 43X splits the difference by growing upward instead of outward. None of the three borrows another one shell, so order to the pistol you actually own.
Why Neptune
Why Small Guns Expose a Bad Press
There is less holster here than on anything else in our Glock range, and less margin for a mold that was scaled rather than measured. What a dedicated 43 pattern gives you:
- A closing point that actually reaches the trigger guard, rather than a generic slimline cavity that lets the pistol pivot inside it.
- No wasted bulk around a gun bought specifically for having none, since we are not leaving room for a taller frame to also fit.
- A mouth that stays open after the draw, which matters when the gun is short enough that reholstering happens largely by feel.
Every shell is heat-formed to order in Middle Tennessee, in a veteran-run shop that has never used an injection mold. More on the bench and the people at it, or see the rest of the Glock line-up.

No variant to pick and no rail to declare. Give us the carry position, the hand and the hardware, and the shell gets pressed for a six-round single stack and nothing else.
