One Brand. Every Glock. Total Concealment.

Glock makes the most popular pistols on the planet — and each model has different dimensions, weight, and concealment challenges. Whether you carry a subcompact Glock 43 for pocket-friendly concealment or a full-size Glock 17 for maximum capacity, your holster needs to match your gun exactly.

This guide covers every Glock model that Front Line builds holsters for, the best carry positions for each, and how to set up your IWB system for daily concealed carry.

Glock Models by Size: Which Do You Carry?

Full-Size: Glock 17, 17C, 22, 22C, 47

The full-size Glocks deliver maximum capacity and barrel length. The Glock 17 is the original 9mm that started it all. The Glock 22 is the same frame in .40 S&W, trusted by law enforcement across the US. The "C" variants feature compensated/ported barrels for reduced muzzle rise — see the best IWB holster for Glock 17C for compensated 9mm carry, and the best IWB holster for Glock 22C for the ported .40 S&W. The best IWB holster for Glock 47 covers Glock's newer Crossover duty pistol — a G17-length slide on a different, duty-oriented frame that needs its own dedicated shell rather than a repurposed G17 holster. The best IWB holster for Glock 34 covers the long-slide competition variant of the G17 — same frame, but a longer 5.31-inch barrel that needs its own dedicated shell for proper muzzle clearance.

Concealment challenge: The longer grip is the hardest part to hide. Strong side carry at 3-4 o'clock works best — your body's natural curve covers the grip.

Front Line fit: The G17, G17C, G22, and G22C share the same frame dimensions and fit the same precision-molded holster (SKU K3817). The G47's different frame geometry means it uses its own dedicated shell rather than the shared G17 mold.

Compact: Glock 19, 23, 32, 45

The sweet spot for concealed carry. The Glock 19 is the world's most popular carry gun — compact enough to conceal under a t-shirt, full enough to fight with. The Glock 23 IWB holster (.40 S&W), the best IWB holster for Glock 32 (.357 SIG), and the Glock 45 IWB holster (crossover frame) share the same compact dimensions. The Glock 19X IWB holster is the inverse crossover — a G19-length slide on the full-size G17 frame — and fits the same compact-slide holster shell.

Concealment challenge: Minimal. The compact frame works in any carry position — appendix, strong side, or behind the hip.

Front Line fit: All four share the same frame and fit one holster (SKU K3818). Whether you carry a G19 or G45, the retention channel locks in the same.

Subcompact: Glock 26, 27, 28

The "Baby Glocks." The best concealment holster for Glock 26 (9mm), the Glock 27 IWB holster (.40 S&W), and the best IWB holster for Glock 28 (.380 ACP) are built for deep concealment. Shorter barrel, shorter grip, lighter weight — designed to disappear.

Concealment challenge: Almost none. These guns vanish in any position. Appendix carry is extremely popular with subcompacts.

Front Line fit: All three share the same subcompact frame (SKU K3826). The precision-molded shell wraps the shorter trigger guard perfectly — no excess material, no wobble.

Slim/Single-Stack: Glock 43, 43X, 48, 42

The slimmest Glocks in the lineup. The best IWB holster for Glock 43 is built for the ultra-compact single-stack 9mm. The G43X adds a longer grip for better purchase while keeping the narrow slide, and the best IWB holster for Glock 48 stretches that same slim single-stack width into a longer, G19-length slide for a better sight radius. The best IWB holster for Glock 42 is the .380 ACP single-stack that started this family — Glock's smallest, lightest pistol, and a natural fit for anyone who finds even the G43 too big. All four are favorites for appendix carry and warm-weather concealment.

Concealment challenge: Essentially zero. These are the easiest Glocks to conceal, period.

Front Line fit: Each of these models has its own dedicated Front Line holster, molded to the narrow single-stack slide width for maximum concealment with zero print. Buy the holster made for your exact model.

Large-Frame: Glock 20, 21

Glock's big-bore full-size guns. The best IWB holster for Glock 20 (10mm) and the best IWB holster for Glock 21 (.45 ACP) share a wider, heavier large frame than the 9mm/.40 full-size models above — more weight to carry, more stopping power per round.

Concealment challenge: The most demanding in the lineup. The extra width and weight require a stiffer gun belt and usually a lower ride height to keep the grip from printing.

Front Line fit: Both share the same large-frame mold, reinforced to handle the extra weight of a full mag of 10mm or .45 ACP without sagging.

Compact Big-Bore: Glock 29, 30

The compact-frame answer to the G20/G21 above. The best IWB holster for Glock 29 (10mm Auto) and the best IWB holster for Glock 30 (.45 ACP) pack the same big-bore stopping power into a frame that carries closer to a subcompact 9mm than to their large-frame siblings. The best IWB holster for Glock 30S fits a slimmer variant that pairs a single-stack-width G36 slide with the same double-stack G30SF frame — a different shell than the standard G30 despite sharing its magazine capacity.

Concealment challenge: Moderate. The shorter grip conceals about as easily as a same-size 9mm — the added weight, not the size, is what carriers notice most.

Front Line fit: Both share the same compact big-bore mold, reinforced for the added weight and recoil impulse of 10mm and .45 ACP.

Don't Carry a Glock?

Everything above still applies — molded fit, adjustable cant and ride height, mag-safe retention — it just means a different shell. If your carry gun is a SIG P365 or Springfield Hellcat, the same buying criteria apply to their micro-compact frames, which are narrower and shorter than any Glock in this guide. Carrying a Smith & Wesson M&P Shield instead? Its thin single-stack profile needs the same gun-specific molding, just on a different shell. The double-stack M&P Shield Plus trades that single-stack magazine for a wider double-stack mold while keeping the same 1.1-inch width, so it needs its own shell too. The newer double-stack M&P Shield X needs its own dedicated mold too, including clearance for its factory optics cut. Same goes for the double-stack Ruger Max-9 — a different frame shape, but the same molded-fit, adjustable-cant fundamentals apply. And if you carry the Ruger RXM — the Magpul-designed compact 9mm that takes Glock 19 magazines — don't assume that magazine compatibility extends to the holster; it still needs a shell molded to its own slide and frame. Carrying a micro-compact .380 instead, like the S&W Bodyguard 2.0? Its manual thumb safety needs a shell cut with clearance for the lever, not a generic pocket-.380 mold. Carrying a Springfield XD Mod.3 instead? Its compact-9mm frame is close in size to a Glock 19, but the factory OSP optics-ready slide needs its own mold, not a Glock-cut shell stretched to fit. Carrying a Kimber Micro 9 instead? It isn't a striker-fired polymer gun at all — it's a single-action, aluminum-frame micro 9mm with a 1911-pattern thumb safety, so the shell needs to clear that safety lever rather than assume a Glock-style trigger guard is all that matters. Carrying a CZ P10 C instead? It's a Glock 19-class compact built to compete directly with it, but its flatter, boxier slide profile still needs its own gun-specific mold rather than a Glock-cut shell stretched to fit. Carrying a Ruger Security-9 instead? It's a full-size gun, not a compact, and it's hammer-fired rather than striker-fired — a bigger shell and a different trigger-guard geometry than any Glock in this guide, so don't assume a full-size Glock mold is close enough. Carrying a Springfield Echelon instead? It's an optics-ready full-size 9mm in the same size class as a Glock 17, but its slide, frame, and optics-mounting system are its own, so it needs an Echelon-specific mold rather than a Glock-cut shell. Carrying a SIG P320 instead? It's a modular pistol, so the grip module, slide length, and optic cut all vary by version — pick a holster molded for your exact P320 configuration rather than a generic SIG shell.

Choosing Your Carry Position

Your Glock model influences which carry position works best. Here's a quick reference:

Carry Position	Best For	Pros	Cons
Appendix (1-2 o'clock)	G19, G43, G43X, G26	Fastest draw, best concealment, easy retention	Can be uncomfortable sitting (for larger guns)
Strong Side (3-4 o'clock)	G17, G22, G19, G45	Comfortable all day, natural draw	Slower draw, can print when bending
Behind Hip (4-5 o'clock)	All models	Excellent concealment standing	Harder to access, uncomfortable in car seats

Front Line's adjustable cant and ride height system lets you dial in any position. A Phillips-head screwdriver is all you need.

Why Your Holster Material Matters

For IWB concealed carry, Kydex beats leather. Here's the short version:

Kydex — consistent retention forever, zero break-in, moisture-proof, one-handed reholstering
Leather — comfortable initially, but stretches, absorbs sweat, and loses retention over time

Front Line uses high-grade Kydex precision-molded to exact Glock specifications. The retention click is the same on day 1 and day 1,000.

What Makes Front Line Different

Precision-Molded for Each Glock Model

Not a "one size fits most" shell. Every Front Line holster is molded to the exact dimensions of your specific Glock group. The retention channel wraps the trigger guard with a crisp click — no rattle, no play.

Mag-Safe Design

Cheap Kydex clones flex under pressure and trip the Glock's magazine release. Front Line's reinforced shell is battle-shaped to guard the release. Your magazine stays locked in during fast draws, physical activity, and daily movement.

IDF-Proven Durability

These holsters are trusted by the IDF and Israel's top covert operators. Over 50 years of military-grade manufacturing. ISO-certified. No warping, cracking, or screw failures — even after years of daily carry.

Adjustable Everything

Cant, ride height, and retention are all adjustable. Dial in your perfect draw angle and concealment depth in minutes.

Setting Up Your Glock IWB Carry

No matter which Glock you carry, the setup process is the same:

Choose your position — appendix for speed and concealment, strong side for all-day comfort.
Adjust cant — 10-15° forward tilt tucks the grip into your body and reduces printing.
Set ride height — lower for concealment, higher for faster grip access.
Wear a proper gun belt — a reinforced belt prevents sagging and keeps everything locked in place.
Dress around the gun — an untucked shirt or slightly oversized t-shirt is usually enough.
