Start with the exact pistol, not just the family name
A left-handed holster purchase goes wrong fastest when you treat GLOCK 43, 43X, and 48 as one fit. They share a slimline family, but holster compatibility is listed model by model. Before you compare holsters, write down your exact model and whether it has a rail or MOS cut.
The Incog X® Holster for GLOCK G43/G48 Pistols - LH is a left-handed, inside-the-waistband hybrid holster built with Safariland. Its supplied fit list covers GLOCK 43, 43X, 43X Rail, 43X MOS, 48, 48 Rail, and 48 MOS, plus Shadow Systems CR920 and PSA Dagger Micro models. If your pistol is not on that list, treat fit as unconfirmed rather than assuming it will work.
What the Incog X LH actually fits
-
Incog X® Holster for GLOCK G43/G48 Pistols - LH: Compatible with GLOCK 43, 43X, 43X Rail, 43X MOS, 48, 48 Rail, 48 MOS, Shadow Systems CR920, PSA Dagger Micro, and PSA Dagger Micro C-1. This is the exact compatibility list to check against your pistol before ordering a left-handed holster.
Incog X® Holster for GLOCK G43/G48 Pistols - LH
-
Incog X® Holster for GLOCK G43/G48 Pistols - LH: Left-handed configuration with three clip strut shims in 1/8", 1/4", and 3/8" sizes. The shims let you adjust how the holster sits against your body, which matters for a left-hand draw and concealment.
Weapon light: decide before you buy
The Incog X is offered in light-compatible and nonlight configurations, and the difference is not cosmetic. A light-compatible holster depends on the light body for retention. If you buy the light version and carry without the light installed, the holster will not have sufficient retention for safe use.
- Carry with a light?: Confirm your light is on the supplied compatibility list: StreamLight TLR-7 SUB (GL), TLR-7 HL-X SUB (GL), TLR-7 X SUB (GL), Surefire XSC (A), or NightStick TCM-5B (S2).
- Carry without a light?: Choose the nonlight version. Do not buy a light-compatible holster and leave the light off.
- Light not on the list?: Compatibility is not confirmed by the supplied information. Treat it as a reason to verify before ordering.
Where the mag caddy changes your setup
The Incog X® Mag Caddy is an optional attachment that carries an additional magazine. It connects at an angle, which the catalog describes as supporting an ergonomic, tactile draw, and it has adjustable retention with the rounds facing forward.
A caddy adds width and a second item to your waistband. That trade-off is worth it if you want a spare magazine in the same draw-side package. If you prefer a slim profile or already carry a separate magazine pouch, the caddy may be unnecessary bulk.
Left hand GLOCK 43 versus GLOCK 48: same holster, different carry feel
The same Incog X LH lists both the GLOCK 43 and GLOCK 48 as compatible, so the holster choice does not change between them. What changes is the pistol you are concealing.
- GLOCK 43: The shorter slide of the 43 makes it the more compact option in this fit list. The holster is compatible, but ride height and comfort depend on your body and carry position.
- GLOCK 48: The longer slide of the 48 is also covered by the same left-handed Incog X. If you want the longer slide, you do not need a different holster model within this fit list.
- 43X and 48 variants: Rail and MOS versions are listed separately, so confirm your exact variant rather than relying on the base model name.
A short pre-purchase checklist
- 1. Confirm your exact pistol model: Match your GLOCK 43, 43X, or 48 variant against the supplied compatibility list, including Rail and MOS designations.
- 2. Decide light or nonlight: If you carry a weapon light, verify it is one of the listed compatible lights. If not, choose the nonlight configuration.
- 3. Decide on the mag caddy: Add it only if you want a spare magazine attached to the holster and accept the extra width.
- 4. Plan for left-hand draw: This holster is left-handed. Confirm your draw side before ordering.
- 5. Use the shims to tune the fit: The included 1/8", 1/4", and 3/8" clip strut shims are there to adjust how the holster sits against your body.
What the supplied information does not tell you
The catalog does not provide a specific ride height, cant angle, or belt width requirement for this holster. It also does not provide a maintenance schedule. Those are not reasons to avoid the holster, but they are details you should confirm from the manufacturer or the holster's documentation before relying on it for daily carry.
The Incog X LH is a multi-positional deep-concealment IWB holster. That description tells you the intended carry style, but it does not guarantee comfort for every body type or every carry position. Adjust the shims and your belt position, and test the setup with an unloaded pistol before carrying.
