The Most Comfortable IWB Holsters for the Glock 43
All-day inside-the-waistband carry with the Glock 43 comes down to three things: how the backer sits against your skin, how precisely the shell holds the pistol, and how much you can adjust the setup to match your body type.
The G43's slim 1.06-inch width is an advantage here -- it is one of the narrower subcompact pistols you can carry IWB, which means less bulk pressing against your hip during extended wear.
The ShapeShift 4.0 IWB is the most feature-complete inside-the-waistband option on this page. It uses a wearable backer with an adjustable mounting system that gives you full control over cant (forward, neutral, or FBI) and ride height independently.
That adjustability matters more than most buyers expect -- small changes in cant or ride height can be the difference between a hotspot after two hours and a carry setup you forget you are wearing. The ShapeShift 4.0 IWB is available in a G43-specific configuration.
The Photon is the most versatile single holster for your Glock 43. It is a full-polymer holster that ships with both IWB and OWB attachment hardware, so you can switch carry modes without buying a second holster. For the G43, the Photon is worth considering if you want a slim, low-profile IWB option that also covers range and open carry days without a separate purchase.
For appendix carry specifically, the ShapeShift Appendix Holster mounts in the AIWB position and is available for the G43.
The G43's short grip height -- 4.25 inches -- makes it one of the most practical subcompact pistols for appendix carry. There is simply less grip to manage than on a full-size or compact pistol, which reduces the pressure and printing challenges that make appendix carry uncomfortable for some people.
The ShapeShift Hook and Loop Holster provides an additional IWB option for off-belt carry situations -- check the product page to confirm the carry configuration that best suits your needs.
How to Choose the Best Glock 43 Holster for Concealed Carry
"Best" for the G43 depends on three buyer-specific factors that no single holster wins on all three simultaneously.
Carry position: Strong-side IWB at 3-5 o'clock suits most first-time concealed carriers and offers the most stable draw stroke. Appendix carry at 1-2 o'clock is faster for many shooters and keeps the pistol in front of the body where you can monitor it.
The ShapeShift 4.0 IWB works well for strong-side IWB; the ShapeShift Appendix Holster is the dedicated AIWB option.
Cover garment: The G43 is slim enough that most cover garments work, but a holster with adjustable ride height lets you tuck the grip lower under a t-shirt when needed. Higher ride height suits thicker cover garments and gives a faster draw stroke.
Modular vs. dedicated: If you carry in one position consistently, a dedicated holster like the ShapeShift 4.0 IWB or Photon is the simpler choice. If you want to switch between IWB, OWB, and appendix carry with the same G43, the ShapeShift Core Carry Pack and ShapeShift Shell give you one platform that covers multiple carry modes at a lower total cost than separate holsters.
OWB Holsters for the Glock 43
Outside-the-waistband carry for the G43 covers three distinct use cases -- open carry and range use, field and outdoor carry, and duty carry -- and each has a different product fit.
For open carry and range use, the ShapeShift OWB Slide Holster and ShapeShift OWB Paddle are the primary options.
The OWB Slide threads onto a standard belt and rides close to the body for a low-profile position. The OWB Paddle attaches and removes without threading through belt loops, which suits shooters who transition between carry environments frequently.
Both are part of the ShapeShift modular system, so if you already own a ShapeShift Shell for the G43, the OWB Slide Expansion Pack adds OWB carry to your existing setup without purchasing a complete second holster.
For field and vehicle use, the ShapeShift Swivel Drop Leg Holster positions the G43 lower on the thigh and is suited for plate carrier use, vehicle carry, or outdoor environments where belt-level access is restricted.
Confirm G43 shell availability on the product page before purchasing.
Duty and Active Retention Holsters for the Glock 43
The Rapid Force Level II Duty Holster is the active-retention option for the G43 on this page. It is available in two configurations: one for the G43 without a weapon light, and one designed for compact Glock platforms with a light attached.
Level II retention means the holster uses one active retention device in addition to passive friction retention -- the standard requirement for most uniformed duty carry applications. Replacement shells are sold separately if you need to switch between the light and no-light configurations.
Confirm that your specific G43 setup (with or without a weapon light, and your light model if applicable) is supported on the product page before purchasing.
The ShapeShift Modular System -- One Shell, Multiple Carry Modes
The ShapeShift system is worth understanding if you are buying a holster for the G43 and want flexibility over time.
The ShapeShift Shell for Glock is the G43-specific core component. Once you own the shell, individual expansion packs -- the ShapeShift 4.0 IWB Expansion Pack, the ShapeShift Appendix Expansion Pack, and the ShapeShift OWB Slide Expansion Pack -- each add a new carry mode at a lower cost than a complete second holster.
The ShapeShift Core Carry Pack bundles the shell with several carry attachments in a single purchase, which is the most cost-effective starting point if you want to cover IWB, OWB, and appendix carry from day one.
Glock 43 Holster Fit -- What You Need to Know
A few compatibility questions come up frequently for G43 buyers:
Does a Glock 43 holster fit the Glock 43X? No. The G43X has a longer grip frame -- 5.04 inches tall versus 4.25 inches on the G43 -- and requires a separate holster shell. A G43-molded holster will not retain the G43X correctly. Alien Gear has a dedicated Glock 43X collection page for that model.
What about the Glock G43 -- is that the same pistol? Yes. "Glock G43," "Glock 43," and "G43" all refer to the same pistol. Every holster on this page fits the standard Glock 43.
Does the G43 have a rail for a weapon light? No. The standard Glock 43 does not have an accessory rail. Light-bearing holster configurations are not applicable to the G43.

FAQ
What is the most comfortable IWB holster for the Glock 43?
The ShapeShift 4.0 IWB is the most adjustable IWB option for the G43, with independent cant and ride height adjustment that lets you eliminate hotspots and find a carry position you can wear all day. The Photon is a strong alternative if you want a single holster that also covers OWB carry. For appendix carry, the ShapeShift Appendix Holster is the dedicated AIWB option for the G43.
What is the best Glock 43 holster for concealed carry?
It depends on your carry position and cover garment. For strong-side IWB carry, the ShapeShift 4.0 IWB offers the most adjustability. For appendix carry, the ShapeShift Appendix Holster is purpose-built for AIWB. If you want a single holster that covers both IWB and OWB, the Photon converts between both modes. If you carry in multiple positions and want one platform for all of them, the ShapeShift Core Carry Pack is the most cost-effective starting point.
Does the Glock 43 holster also fit the Glock 43X?
No. The G43X uses a different grip frame that is 5.04 inches tall versus 4.25 inches on the G43. A G43 shell will not seat or retain the G43X correctly. Alien Gear has a dedicated Glock 43X holster page with shells built specifically for that model.
Is there a duty holster with active retention for the Glock 43?
Yes. The Rapid Force Level II Duty Holster is available for the G43 in both a no-light and a compact light configuration. Level II retention adds one active retention device on top of passive friction retention, which meets standard duty carry requirements for most agencies. Confirm G43 compatibility on the product page before purchasing.
What is the ShapeShift Core Carry Pack and is it worth it for the G43?
The ShapeShift Core Carry Pack bundles the G43-specific ShapeShift Shell with multiple carry attachments -- covering IWB, OWB, and appendix carry modes in a single purchase. If you want to carry in more than one position or are not yet sure which carry style suits you best, it is the most cost-effective way to start. Individual expansion packs are also available if you want to add carry modes to an existing shell over time.
Does the Glock 43 have a rail for a weapon light?
No. The standard Glock 43 does not have an accessory rail. Light-bearing holster configurations are not applicable to the G43. If you own a Glock 43X -- which does include the Glock Slim Mounting Rail on MOS models -- see the dedicated Glock 43X holster page for light-compatible options.
Are Glock 43 holsters available for left-handed shooters?
Yes. Left-hand draw configurations are available across the IWB, OWB, appendix, and duty lines for the G43. Hand orientation is selected at the product level.
