The Glock 43 is a single-stack subcompact 9mm — 6.26″ long, 1.06″ wide, 4.25″ tall, about 18 ounces unloaded, with a 3.39″ barrel and a 6-round magazine. Its slim, light build is a big part of why it works reasonably well as an ankle-carry gun; a full-size or even compact pistol is generally too heavy and bulky for comfortable, printing-free ankle carry over any real distance.
Fit specifics: G43 vs. G43X
Glock’s 43X shares the 43’s overall length and slide, but the grip is meaningfully taller — 5.04″ versus the G43’s 4.25″ — to fit a longer magazine and give a fuller firing grip. That grip-height difference is exactly the dimension an ankle holster is built around, since the holster has to cradle the grip against the calf without the gun rotating or shifting. Some ankle holsters are listed as fitting both models, but always check that the specific listing accounts for the 43X’s taller grip rather than assuming a G43-only mold happens to stretch to fit — a loose fit on a moving ankle is worse than a loose fit almost anywhere else on the body, since the leg is in constant motion.
Why ankle carry is a specific-use case, not a default
Ankle holsters are almost always a backup-gun or specific-clothing-situation choice rather than a primary carry method. The draw is slower than from the waistband — you typically need to crouch, kneel, or lift a pant leg to reach it — and comfort during walking or driving varies a lot by holster design and how it interacts with your particular gait. Where ankle carry earns a place is as a genuine backup piece worn alongside a primary waistband gun, or when clothing rules out waistband carry entirely (certain dresses, athletic wear, or professional attire where nothing at the waist is an option).
Retention for a holster that moves with every step
Because the gun rides low and moves with every step rather than staying relatively still against the torso, retention matters more here than on a static waistband holster. A secure strap — thumb break, hook-and-loop closure, or magnetic closure — is standard on ankle holsters for exactly this reason, and passive friction alone is a weaker choice on a rig subject to this much constant motion. Check that the strap engages positively and doesn’t loosen on its own after repeated walking, which some hook-and-loop designs do over months of wear.
Material trade-offs
Neoprene is the most common ankle holster material because it stretches with the calf, manages sweat reasonably well against skin worn all day, and stays comfortable through a lot of walking. Leather ankle holsters offer a firmer, more structured retention shape and can feel more secure, but they don’t flex with the leg the way neoprene does and can be less forgiving against bare skin in warm weather. Either is a legitimate choice; the deciding factor is usually comfort against your specific leg, sock height, and the boots or shoes you actually wear the holster under. A sweat-wicking liner matters more here than almost anywhere else on the body, since an ankle holster sits directly against skin, under a sock or against bare skin, all day in a way most other carry positions don’t.
Carry mechanics: strap, draw, and printing
Most shooters find the inside of the ankle — facing the other leg — more comfortable and easier to conceal than the outside, and most ankle holsters are worn on the leg opposite your dominant kicking or support leg. A wide, padded calf strap that adjusts to fit ankles up to roughly 13″ is what keeps the gun’s weight from digging in or sliding down through a day of wear; a strap too narrow or under-padded for your calf size is the most common reason people give up on ankle carry as uncomfortable. Try the holster with the actual boots or pant styles you’ll wear it under before committing — a holster that conceals cleanly under loose jeans can print badly under slim-cut pants, and pant cut is the real limiting factor on whether ankle carry is even viable for your wardrobe.
Position-specific practical note
Drawing from an ankle holster generally requires bringing your foot up onto a raised surface, kneeling, or bending at the waist — there’s no fast standing draw the way there is from the waistband, which is exactly why ankle carry works best as a backup position rather than a primary one.
Evaluating an ankle holster yourself
- A mold specific to your exact model — G43 or G43X — accounting for the grip-height difference between them.
- A positive-engaging retention strap, not friction alone.
- A wide, padded calf strap sized correctly for your leg, adjustable up to about 13″.
- Comfortable and non-printing under the actual pants and footwear you’ll wear it with, not just in isolation.
- A sweat-wicking liner if you plan to wear it against bare skin for extended periods.
