g43 vs g43x Holster: How to Choose the Perfect Fit and Comfort

The g43 vs g43x holster choice hinges on size and design differences that prevent full interchangeability. The G43X is larger and taller, requiring holsters molded to its specific dimensions, while the smaller G43 fits better in slimmer, more compact holsters. Choosing the right holster ensures comfort, accessibility, and optimal firearm retention for each model.

This comparison is for Glock 43 and 43X owners or prospective buyers seeking a precise fit and comfort from their concealed carry holsters. You’ll learn how to select a holster that matches your gun’s dimensions, accommodates features like optics, and delivers reliable daily carry performance.

Are Glock 43 and 43X Holsters Interchangeable?

You generally cannot use a Glock 43 holster for a Glock 43X without issues because the 43X is larger in size. The G43X’s wider frame and magazine accommodate 10 rounds instead of the G43’s single-stack design, which affects holster compatibility. Using a holster designed solely for the Glock 43 may result in a loose fit that compromises retention and security during carry.

Many holsters specify compatibility with both models (“G43/43X”), made possible by similarities in the slide and some frame contours. However, holsters labeled only for the G43 often lack the necessary width and retention adjustment to securely fit the larger 43X. Carrying your 43X in a G43-only holster risks excessive movement, reduced comfort, and possible safety concerns.

Checking holster fit before your first carry session is essential. Insert your firearm fully and verify that it seats firmly without excessive wobble but also allows a smooth draw. Holsters with adjustable retention using screws or friction fit can help accommodate minor dimension differences. If in doubt, choose a holster specifically designed with G43X compatibility to improve security and comfort.

When selecting a holster, look for adjustable retention features, like those tightened with a Phillips screwdriver, to adapt better between models if the manufacturer claims multi-model compatibility. Testing the holster with your firearm, preferably on your body in your usual carry position, reveals how well it supports comfort and security. Avoid forcing a G43 into a holster designed strictly for the 43X or vice versa, since even minor gaps can cause unsafe movement or holster wear.

How Size and Design Differences Affect Holster Fit

The key size difference between the Glock 43 and Glock 43X that affects holster fit is the grip length. The G43X has a grip height of about 5.04 inches, approximately 0.79 inches taller than the G43’s 4.25 inches. This longer grip accommodates a 10-round magazine versus the G43’s 6-round capacity. The slide length and barrel are the same in both models, with lengths close to 6.26 inches, so holster designs mainly need to adapt to the grip differences rather than overall length.

Grip length impacts retention and concealment significantly. Holsters made for the G43, with its shorter grip, may not fully cover the G43X’s extended grip, leading to less secure retention or exposed grip area that can catch on clothing. Conversely, a holster designed for the G43X’s longer grip tends to be bulkier, which might slightly reduce concealment for the smaller G43. This tradeoff means the best fitting holster will often be model-specific to balance secure retention with discreetness based on your carry priorities.

Slide and barrel width also matter but are less of a differentiator between these models. The G43 slide width measures about 0.87 inches, and the G43X’s slide is nearly the same at 0.86 inches. With such close dimensions, the molding of the holster’s slide channel requires only minor adjustments between models. Holster manufacturers typically focus on the grip profile change, as the controls’ width slightly decreases on the G43X (1.05 inches versus 1.07 inches on the G43), which can affect trigger guard fitting and overall holster tightness.

When selecting or crafting a holster, precise measurements make a difference. For example, choosing a Kydex holster tailored to the G43X ensures the longer grip is fully enclosed, helping retention and preventing wear on the firearm. For IWB holsters, this grip extension often requires holsters with a deeper pocket or an adjustable sweat guard to accommodate the taller profile comfortably against the body.

Always check holster dimensions against your specific model to avoid improper fit that causes retention failure or poor concealment.

Best Holster Types for Glock 43 and 43X Models

The Glock 43 and 43X work well with several holster types, each suited to different carry methods and user preferences. Inside-the-waistband (IWB) holsters offer strong concealment for both models. Outside-the-waistband (OWB) holsters provide comfort and quick access, mainly for open carry. Appendix and pocket holsters suit users prioritizing discretion and convenience, with some differences based on the gun’s size.

Inside-the-Waistband (IWB) Holsters

IWB holsters are the most popular choice for concealed carry with the Glock 43 and 43X since they offer excellent concealment by sitting inside your waistband. The G43’s smaller frame fits comfortably in most slim IWB holsters, making it easy to hide under a shirt without printing. The 43X is slightly larger, so holsters designed specifically for it provide a more secure and comfortable fit. A few IWB holsters include adjustable cant and ride height to suit strong-side or appendix carry positions. Many also offer passive retention to keep your pistol secure while seated or moving.

• Strong concealment and retention for everyday carry
• Adjustable features fit different body types and carry preferences
• Compatible with optics-ready versions on the 43X MOS models
• Can carry with weapon lights if designed for light-bearing models
• Requires a belt thick enough to support the rig securely
• May take some time to break in leather or Kydex hybrid models for comfort

Price for quality IWB holsters ranges from $40 to $100 or more, depending on materials and customization. Brands with hybrid designs or ambidextrous features tend to cost more but provide better comfort and versatility.

Outside-the-Waistband (OWB) Holsters

OWB holsters offer easier access and superior comfort for extended wear but are less concealable without an outer garment. Both the Glock 43 and 43X can be carried OWB if concealment is less critical or during open carry situations. The 43X’s larger grip and frame make it a natural fit for many OWB holster models designed for compact pistols. Some OWB holsters are molded specifically for Glock 43X series, including optics-ready versions, giving a secure fit, adjustable cant, and retention options.

• Faster draw and easy reholstering
• Greater comfort for all-day wear
• Works well for open carry or casual concealed use (with a jacket or shirt)
• More visible, less suited for strict concealment
• Can accommodate attached weapon lights or slides with optic cuts
• Usually requires a sturdy belt and proper positioning for comfort

Expect to spend $30 to $80 for a dependable OWB holster suitable for both Glock 43 and 43X models, with optic-ready variations on the higher end.

Appendix and Pocket Holsters

The short barrel and slim profile of both Glock pistols make them excellent candidates for appendix carry. Holsters designed for appendix carry are often compact, slim, and provide strong retention while minimizing printing. Glock 43 appendix holsters are smaller and simpler due to the gun’s size, while 43X appendix holsters tend to be slightly larger to fit the extended grip comfortably but still conceal well with the right design.

Pocket holsters work well with the Glock 43’s slim build, allowing easy carry in a front pocket without a bulky feel. The 43X is taller and wider, so pocket holsters for it exist but tend to be bulkier and less comfortable in smaller pockets. Pocket holsters for the 43X require deeper or reinforced pockets to manage the grip securely and prevent the gun from shifting.

• Appendix carry holsters offer secure, quick access for both models
• Compact design minimizes printing in appendix position
• Pocket holsters fit comfortably with Glock 43, less so with 43X due to size
• Good retention is critical to avoid accidental exposure or movement
• Leather and hybrid materials provide comfort and mold well to the body
• Appendix carry demands careful placement and awareness to avoid discomfort

Appendix and pocket holsters cost between $30 and $75 depending on materials and features. Testing holster fit and comfort before extended wear is important for both carry methods to ensure safety and ease of access.

Key Features to Look for in G43 and G43X Holsters

Retention is key for both Glock 43 and G43X holsters to ensure your pistol stays secure but remains easily accessible. Most quality holsters use adjustable retention screws that let you tighten or loosen how firmly the holster grips your gun. Start with the screw a quarter turn at a time and test the draw to find your preferred balance between security and quick access. Over-tightening can make the gun hard to draw quickly, while too loose risks the pistol shifting or falling out during movement.

The material of the holster plays a major role in comfort and durability. Kydex is a common choice for G43 and G43X holsters because it offers a rigid, lightweight, and durable shell that holds shape well for consistent retention. Look for Kydex thickness around 0.08 inches which provides a good balance between strength and comfort. Some holsters add a full sweat guard to protect both you and your pistol from moisture and abrasion, increasing longevity. Leather options provide more comfort by molding to your body over time but require more maintenance and tend to be bulkier.

Cant, or the angle of the holster relative to your body, affects concealment and draw speed. For the narrower Glock 43, a slight forward cant around 15 to 20 degrees often improves concealment under a shirt by allowing the grip to tuck behind your waistline better. The slightly taller G43X can handle a 20 to 30-degree cant, helping the grip clear your clothing for faster presentations while still maintaining a low profile. Most adjustable cant holsters use clip or screw mechanisms that let you set and lock your preferred angle without tools or with simple screwdrivers. Try adjusting your cant in small increments until your draw is smooth and the pistol remains discreet under your typical clothing.

• Adjust retention screws gradually, checking draw tension each time
• Choose 0.08-inch thin Kydex for a durable, lightweight holster
• Consider full sweat guards for moisture protection
• Start cant adjustments at 15 degrees for G43, up to 30 degrees for G43X
• Look for holsters with adjustable ride height to customize your carry position
• Ensure clip design supports your preferred carry orientation and belt thickness
• Test holster comfort during typical daily activities to confirm fit

Retention and cant affect not only comfort but also safety, preventing accidental slips or difficulty drawing in critical moments. Durable materials like Kydex also withstand sweat and daily wear better than many fabrics, protecting your investment and gun. Customizing these features takes minimal tools and time but dramatically improves your concealed carry experience with these slim-profile pistols.

Holsters Compatible with Glock 43X MOS and Optic Versions

The Glock 43X MOS requires holsters with specific optic cuts to clear mounted red dots, ensuring proper fit and reliable retention. Holsters made for the MOS version include adjustable retention and molded shapes that accommodate both optics and accessory rails. Using a holster designed for the standard 43X or 43 without an optic can result in poor fit and compromised safety.

Popular MOS-Ready Holsters

Several holsters cater specifically to Glock 43X MOS shooters, combining optics clearance with solid retention and carry comfort. These models typically use durable polymer like Boltaron or Kydex, offer adjustable retention screws, and include multiple carry options such as inside-the-waistband (IWB) and outside-the-waistband (OWB). Popular choices include:

• IWB holsters with molded optic cuts and adjustable retention for red dots like the Shield RMSc or Trijicon RMR
• Holsters made for Glock 43X MOS with Streamlight TLR-7 Sub light compatibility that ensure the light and optic fit fully
• Ambidextrous, adjustable holsters compatible with Glock 43X MOS, Glock 48 MOS, and similar-sized optics-ready pistols
• Holsters featuring concealment claws or retention-adjustment screws to optimize draw speed and weapon stability
• Polymer holsters with included belt clips or OWB paddles for varied carry modes

Prices for these holsters typically range from around $40 to $80 and come with warranties between one and two years, reflecting their build quality and brand support.

Custom Optic Cut Features

Holsters made for the Glock 43X MOS have precise cuts to clear slide-mounted optics, preventing contact that could damage the sight or interfere with drawing. They also accommodate the accessory rail, unlike standard 43X holsters that can create tension or leave the slide partly exposed. To fit an optic-mounted 43X correctly, the holster needs:

• Exact measurements for the optic housing width and height to avoid binding
• Retention systems that secure the pistol firmly without squeezing the optic
• A molded shape that ensures full seating of the firearm, including light attachments if applicable

Holsters designed around specific optics, such as the Shield RMSc or Trijicon RMR, provide tailored protection and ease of use. Features like adjustable retention screws and concealment claws help customize carry tension and positioning for quicker draws and improve comfort.

Using Non-MOS Holsters with Optic-Mounted Guns

Standard Glock 43X or 43 holsters without optic cuts generally do not fit the MOS versions with mounted red dots properly. The slide-mounted optic adds extra height and bulk, which can cause the pistol to sit unevenly, creating muzzle drag or making the holster difficult to don and doff. Using a non-optic holster with a 43X MOS gun can result in:

• Damage to the optic from excessive pressure or rubbing against the holster
• Reduced retention security and increased risk of weapon shifting or falling out
• Slower draws caused by binding or catch points on the optic

Always ensure your holster matches your 43X’s configuration and accessories to maintain safety and usability.

For those switching between optic and non-optic versions, investing in dedicated holsters for each setup or modular holsters designed to adapt with an optic insert is advisable. This approach prevents damaging your equipment and guarantees consistent carry performance.

Top Recommended Holster Brands for Glock 43 and 43X

Multiple holster manufacturers provide dependable and comfortable solutions for everyday carry, designed specifically for Glock 43 and 43X users. The CYA Supply Co Base IWB Holster Carbon Fiber is often recognized as a leading option by many firearm owners. It offers toughness, a snug fit for the G43X, and adaptability for different carry styles. For owners of the 43X MOS model equipped with a red dot, opting for a premium leather holster that supports both hands and includes tuckable clips improve both comfort and functionality.

Affordability without compromising quality comes from brands like POLE.CRAFT, which offers an IWB Kydex holster compatible with both G43 and G43X. This model delivers value by managing a secure fit and comfort at a budget-friendly price point. For those needing deep concealment and a minimalist profile, especially smaller framed individuals, a dedicated slim Kydex IWB holster designed specifically for the G43 may be preferable. Carrying a G43X in a Glock 48 holster is also possible but usually not optimal for comfort compared with holsters designed for the exact model.

The CYA Supply Co Base is strong in reliability and comfort with optics-ready design, ideal for Glock 43X users who want premium features. Its ambidextrous fit and tuckable C-Clip make it adaptable across different carry preferences. The premium leather option stands out for those seeking classic materials with optics compatibility but involves a slightly higher price and shorter warranty.

POLE.CRAFT offers the best value holster for all-day carry at a budget price with sufficient quality for secure G43 or 43X use. Its simple design lacks optics accommodation, making it more suited for users without red dot sights. Slim Kydex holsters tailored to the G43 favor minimal footprint and deep concealment but do not support optics or ambidextrous carry. Choosing among these depends on your priorities, comfort, optics readiness, or budget, along with how you carry and which model you own.

Common Holster Fit Mistakes and How to Avoid Them

One common mistake that causes holsters to print or feel uncomfortable with the G43X is using a holster designed for the smaller G43. The G43X is slightly larger and heavier, so a holster that fits the G43 too snugly can create pressure points and restrict movement. Poor retention often happens because users don’t adjust the retention screws or select a holster without retention features suited to the G43X’s size. Slow draws are frequently caused by incorrect cant angle or overly stiff retention that hasn’t been personalized. To avoid these issues, check the following common fit mistakes:

• Using a holster sized only for the G43 on a G43X without adjusting retention.
• Ignoring adjustable retention screws or missing them entirely.
• Selecting holsters with fixed cant angles that don’t match your draw style.
• Failing to verify deep carry capability for printing concerns.
• Neglecting to test holster compatibility if aftermarket extensions or laser attachments are added.
• Choosing holsters made from overly stiff materials without break-in time.

Improving your holster fit begins by verifying compatibility with your exact model. If your G43X holster causes printing or discomfort, loosen retention screws incrementally, about a quarter turn at a time, and test the grip security. Holsters with adjustable retention like the Posi Click system provide audible cues that the gun is properly seated, improving confidence in retention. Adjust the cant angle in steps up to 60 degrees to find the best natural draw path. Carrying deep can reduce printing with the G43, but with the G43X’s slightly larger frame, moderate cant adjustments often improve concealment without sacrificing accessibility.

Modifications may also include break-in for holsters made of rigid Kydex or leather to soften edges that dig into skin. This can take several days of pocket carry or targeted bending. For laser/light attachments compatible with your G43X, confirm the holster is cut or molded to accommodate them. Otherwise, expect poor fit or obstruction during draw.

Seeing good results means your firearm should be secure yet quick to draw, and comfort should prevent you from shifting or adjusting the holster throughout the day. A poor fit often reveals itself by inconsistent retention or printing when moving. Regularly testing your holster fit with your fully loaded G43X when wearing daily carry clothing is key. Adjustments and choosing the right holster style go a long way in balancing comfort, retention, and speed at the draw.

How to Choose Your Ideal G43 or G43X Holster

You should choose your G43 or G43X holster based on your carry style, hand size, and specific needs for concealment versus comfort. Selecting a holster designed for your exact model ensures a proper fit and reliable retention. Adjustability, material, and real-world testing also play key roles in finding the best match.

Assess Your Carry Style and Needs

Identify how you plan to carry your Glock 43 or 43X first. Common options include inside the waistband (IWB), outside the waistband (OWB), pocket carry, or appendix carry. Your daily activities and clothing will affect which style feels natural and stays concealed.

Hand size affects draw speed and comfort, especially with compact models like the G43 versus the longer 43X. Consider if you want a holster that supports a right-hand draw specifically and whether features like adjustable cant or ride height matter to you.

Measure and Match Holster Fit

Accuracy in fit prevents holster movement and ensures the firearm stays secure. Use a measuring tape or calipers to compare your gun’s exact dimensions to the holster specs. Many holsters specify model compatibility, so choose one labeled explicitly for your Glock 43 or 43X. Avoid holsters listed simply as ’43’ if you have a 43X, since magazines and frame sizes differ.

A proper fit includes the thickness of materials like .08-inch Boltaron, which provides durability without excess bulk. Pay attention to retention adjustments and whether the holster accommodates optics if applicable, such as the 43X MOS version.

Consider Adjustability and Material Preferences

Holsters offer adjustability in cant, ride height, and retention tension, especially in polymer or Kydex models. Adjustability lets you fine-tune comfort and concealment to your body and carry position. Leather options may be more comfortable but less adjustable and durable under heavy use.

Materials affect weight, breathability, and durability. Holsters constructed with precision molding CNC milling provide exact fits but usually cost more. Foam backers add padding but increase bulk. Your budget and everyday use will guide which materials work best.

Test Concealment and Comfort in Real Scenarios

Take time to wear your holster with your firearm around the house or during typical activities to test concealment and comfort. Adjust ride height and cant as needed to minimize printing through clothing. Consider whether you’d rather sacrifice some concealment for better comfort during long wear or if maximum concealment is the priority.

Be mindful of how the holster feels when sitting, bending, or walking. A poor fit can lead to discomfort or printing, reducing your willingness to carry consistently. Holsters designed specifically for the Glock 43X with optics often include cutouts and adjustability to help balance these factors.

1. Identify your preferred carry style (IWB, OWB, pocket, appendix).
2. Measure your firearm and compare it to holster model specifications.
3. Choose a holster constructed for your specific Glock 43 or 43X variant.
4. Evaluate materials based on comfort, durability, and your budget.
5. Check for adjustability features like tension screws, cant, or ride height.
6. Wear the holster in various clothing and positions to test concealment.
7. Adjust settings to improve comfort or concealment based on your priority.

Always verify holster compatibility with your exact Glock model to avoid poor fit and unsafe retention. Using a holster meant for a different model can compromise draw and retention security.
