Will a Glock 47 Fit in a 17 Holster? Complete Compatibility Guide & Tips

A Glock 47 typically fits into a Glock 17 holster because their frame sizes are very similar. The Glock 47’s dust cover is shorter, but this difference doesn’t impact how it fits or stays secure in the holster. Try placing your Glock 47 in a Glock 17 holster without any attachments to confirm the fit.

Will a Glock 47 Fit in a Glock 17 Holster?

The Glock 47 will generally fit in a Glock 17 holster without significant issues. Both pistols share almost identical slide length and overall dimensions, which are the main factors holsters rely on for secure fit and retention. The slide area is where the holster grips and holds the firearm, so matching slide length is a key compatibility rule. Because the Glock 47’s slide length aligns closely with the Glock 17, holsters designed for the Glock 17 usually accommodate the Glock 47 well.

The main difference between these two models is the Glock 47 has a shorter dust cover on its frame compared to the Glock 17. However, this shorter dust cover does not affect how the holster fits or retains the gun. Holsters typically do not rely on the dust cover to provide grip or secure the firearm. Instead, they engage the slide, which maintains a consistent profile between the two guns. This means you can expect the Glock 47 to slide easily into a Glock 17 holster and stay securely in place, even with the shorter dust cover.

Some holsters, especially those made from rigid materials like Kydex or those with adjustable retention screws, can accommodate slight variations in dust cover length without loss of retention or comfort. Using a holster with retention adjustment can further ensure the Glock 47 fits securely in a Glock 17 holster. For holsters designed with a closed bottom or tight hold on the dust cover area specifically, the shorter dust cover might reduce some contact area. In these rare cases, retention could feel slightly less tight unless adjusted, but overall fit remains good.

Determine if a holster made for your Glock 17 will fit your Glock 47 by checking whether it holds the firearm mainly around the slide and features adjustable retention. Make sure the holster’s slide length matches the Glock 47 to prevent fit problems. Holsters that grip the slide instead of the frame’s dust cover work better with the Glock 47, since it has a shorter dust cover. Sometimes, especially with holsters that have open bottoms or adjustable retention, no changes are needed to fit a Glock 47 in a Glock 17 holster securely.

In contrast, some holsters made exclusively for more compact models like the Glock 19 or specialized Glock 43X MOS will not fit either the Glock 17 or Glock 47 properly due to different slide lengths and frame dimensions. But for holsters labeled for Glock 17, wearing a Glock 47 generally requires no additional fitting or concerns. You may choose a dedicated Glock 47 holster for tailored fit or features, but compatibility is not a problem with standard Glock 17 holsters.

Key Design Differences Impacting Holster Fit

The slide length is a key element in holster compatibility. The Glock 47 shares the same full-size slide and barrel length as the Glock 17, measuring 114 mm (4.49 inches). Because the holster mainly grips the slide and frame, this matching length ensures the Glock 47 fits securely in most Glock 17 holsters. However, the frame design and certain external features create small but important differences.

The Glock 47 has a slightly shortened dust cover compared to the Glock 17, which affects how the holster’s internal channels engage the frame. Frame width and contour are nearly identical but can differ subtly in places like the trigger guard shape and accessory rail geometry. These differences play a role in how snugly the pistol fits within the holster and whether certain holsters will hold the Glock 47 as firmly as the Glock 17.

Generational changes in Glock pistols show how even documented design updates may not dramatically alter holster fit. For example, the transition from Gen 4 to Gen 5 involved over twenty design changes, but the external frame and slide dimensions remained close enough that the new pistols often fit holsters made for the previous generation. The same principle applies to the Glock 47’s design in relation to the Glock 17. While some internal modifications exist, they typically don’t impact external holster fit.

Check your holster’s retention and comfort with your Glock 47 before everyday carry, especially if it was designed for a Glock 17 without factoring in the shortened dust cover and accessory rail differences.

Keeping in mind the frame and accessory rail differences, the best results come from using holsters specifically tested or designed for the Glock 47, or those explicitly rated as compatible. Most standard Glock 17 holsters will accept a bare Glock 47 due to their matching slide length and similar frame size. However, holsters tailored for mounts, weapon lights, or optics may require adjustments or dedicated versions to accommodate any mounting system on the Glock 47.

Using a Glock 17 Holster with Accessories on the Glock 47

Glock 17 holsters generally fit the Glock 47 without accessories reasonably well due to their similar dimensions. However, adding weapon lights or optics to your Glock 47 can create fit and retention issues in a holster designed solely for a standard Glock 17. Solutions involve selecting holsters with adjustable retention, extra clearance, or choosing holsters specifically molded for Glock 47 models with attachments.

Compatibility with Weapon Lights and Lasers

The accessory rail on the Glock 47 changes the dust-cover shape and wider profile where lights or lasers mount. Most Glock 17 holsters are designed for a clean frame and do not accommodate added bulk from mounted weapon lights or lasers. This results in difficulty fully seating the firearm into the holster or compromised retention, increasing the risk of the pistol shifting or falling out.

Holsters made from flexible materials like Kydex with adjustable retention screws often provide the best solution. The adjustable tension lets you compensate for the extra thickness of an attached light or laser, maintaining a secure hold. Open-top holsters or those with flexible mouth openings also handle accessory bulk better than rigid leather or fixed-mold types.

Holsters Designed for Optic-Ready Glock 47

Optic-ready Glock 47s feature slide cuts for red-dot sights, which many Glock 17 holsters don’t account for. Using a Glock 17 holster with an optic-ready Glock 47 often leads to a poor fit since the slide’s footprint is altered by the mounted optics. Retention can suffer if the holster’s internal shape does not provide clearance for the optic, causing uneven wear or difficulty drawing the pistol.

Holsters molded specifically for the Glock 47 with optics integration provide clearances for mounted red dots and often allow smooth draw and return. The Photon holster is one example popular for concealed and OWB carry that clears common optics and offers compatibility with compact weapon lights. Choosing these holsters ensures better retention, comfort, and durability than trying to fit optics onto a traditional Glock 17 holster.

Using 1913 Rails and Attachment Keys

The Glock 47 uses the standard accessory rail (often the 1913 style) compatible with many tactical lights and lasers. When adding attachments, consider how the rail thickness and length affect holster fit. Some holsters only accept specific rail profiles and may need modification or special inserts for proper weapon seating. Here’s a checklist for ensuring rail and accessory compatibility with your holster:

• Verify the rail profile matches holster specifications (e.g., 1913 Picatinny)
• Check for sufficient holster mouth width to accommodate mounted accessories
• Choose holsters with adjustable retention for thicker frames
• Consider holsters designed for MOS (Modular Optic System) versions for better optic fit
• Look for holsters compatible with left- and right-hand configurations if you switch carry hands
• Test draw and reholster with accessories mounted before committing to carry
• Allow extra time for break-in on new holsters with mounted lights or sights

Accessory mounting can affect the depth and position of how the Glock 47 sits in a Glock 17 holster. You might need to slightly modify polymer holsters for a better fit, but avoid forcing the gun into a holster that resists fully accommodating the attachments. Selecting a holster designed with these attachments in mind is a safer and more reliable path.

Best Holster Options Specifically for Glock 47

Holsters made specifically for the Glock 47 offer a tailored fit that matches the exact dimensions, contours, and, if applicable, optic configurations of this model. This precise molding improves both comfort and firearm retention. Dedicated Glock 47 holsters typically feature adjustable retention systems that allow you to customize the firmness, improving security during rigorous movement or duty use.

The advantage of a dedicated mold lies in how the firearm seats firmly and consistently in the holster. This reduces the chances of shifting or loosening, which directly benefits draw speed and security. Dedicated Glock 47 holsters designed with red dot sight (RDS) cutouts accommodate common optics without compromising retention or ease of draw. This is particularly useful if you carry your Glock 47 with a mounted optic.

Choosing a holster molded to the Glock 47’s unique shape improves access and secures the firearm better than a Glock 17 holster, even though the latter often fits. A custom fit prevents wobbling and ensures the trigger guard is properly shielded. This fit consistency improve your confidence during quick draws or defensive maneuvers.

Finding a holster specifically molded for the Glock 47 usually means paying attention to your intended use. For example, law enforcement professionals often select holsters with improve retention and durability to meet duty requirements. Conversely, a Glock 17 holster might be more affordable and immediately available but could compromise some degree of comfort or security during extended carry or fast draws.

Determining how to order or identify a dedicated Glock 47 holster involves verifying the manufacturer’s specified compatibility and looking for terms like “Glock 47 mold” or “optic-cut for Glock 47.” Dedicated molds come at various price points depending on materials and features, with some options ready to ship immediately to meet urgent needs. Using the right holster ensures your Glock 47 is securely retained, easy to access, and comfortable for long carry periods.

Choosing the Right Carry Style for Your Glock 47 Holster

Choosing the right carry style for your Glock 47 holster depends on your daily needs, comfort, and concealment preferences. Inside waistband (IWB), outside waistband (OWB), and shoulder holsters each offer distinct advantages and drawbacks. Matching your carry method with your lifestyle ensures better retention, faster access, and all-day wearability.

Inside Waistband (IWB) Carry Benefits

IWB carry holds the Glock 47 close to your body, making it one of the best options for concealment. Because the full-size frame tucks inside your pants, it reduces printing even with lighter clothing. Comfort can be a challenge during long wear, but quality IWB holsters use features like neoprene backers to spread the slide’s weight and minimize pressure points.

For example, the Cloak Tuck 3.5 offers a CoolVent neoprene backer, tool-free adjustment for cant and ride height, and all-day comfort suited to the Glock 47’s size. Using a wedge accessory can improve comfort and reduce grip pressure.

• Best for concealment under casual or business attire
• Close retention reduces weapon movement during activity
• Neoprene backing helps distribute pressure
• Requires belt sturdy enough to hold the weight
• Drawing speed can be slightly slower than OWB
• Appended styles like appendix carry offer quick access but may impact comfort when sitting

Wearing a sturdy belt designed for holsters improve retention and comfort in IWB carry.

Carefully adjust cant and ride height to find the spot where the Glock 47 feels secure but accessible. Test different positions before settling on your carry spot to avoid discomfort.

Outside Waistband (OWB) Carry Considerations

OWB holsters offer excellent comfort and faster draw speeds because the firearm sits outside the waistband, reducing pressure on the hips. For the Glock 47, OWB holsters must securely hold the full-size slide to prevent sagging or flagging during movement.

OWB setups are ideal when you can wear a jacket or overshirt to conceal your pistol. The extra space on the holster outside your body allows adding accessories like weapon lights without compromising retention.

• Greater comfort with less pressure on hips and waist
• Faster and more natural draw stroke
• Suitable for open carry or relaxed cover garments
• Allows attachment of lights or lasers easily
• May print more under lightweight or tight clothing
• Better suited for off-duty or range use

Always wear an outer garment like a jacket or untucked shirt when using OWB for concealed carry with the Glock 47.

OWB holsters precision-molded for the Glock 17 also fit the Glock 47 reliably, especially models designed with adjustable retention and sweat guards. Choose holsters with a slim profile and durable materials like kydex or leather for stability.

Shoulder Holster Options for Glock 47

Shoulder holsters offer an alternative carry method that distributes the Glock 47’s weight across your upper body, reducing lumbar pressure common with belts. They are practical when seated for long periods or when waist carry isn’t possible.

Good shoulder holsters feature adjustable harnesses and retention systems to keep the Glock 47 secure but accessible. Leather and synthetic options vary in breathability and comfort, with leather usually requiring a break-in period. Shoulder carry works best with jackets or loose outerwear for concealment.

• Weight distribution relieves lower back strain
• Quick access with practiced reach and draw
• Conceals well under outer garments
• Can interfere with arm movement if poorly fitted
• Requires regular adjustment for comfort
• Less common, so fewer off-the-shelf holsters available

Practice drawing from your shoulder holster regularly to maintain smooth, safe access to your Glock 47.

Choosing a shoulder holster molded specifically for the Glock 47 ensures reliable retention and a proper fit. Consider harness designs with padded straps to improve comfort during longer wear periods.

Materials and Construction: What to Expect in Glock 47 Holsters

Glock 47 holsters come in several common materials, each affecting fit, retention, and comfort differently. Leather remains popular for its natural feel and flexibility. Over time, leather holsters can slightly conform to the shape of your Glock 47, improving fit and comfort. However, leather requires a break-in period of several weeks and occasional conditioning to prevent drying or cracking. It offers moderate retention but may need adjustments or added straps for secure carry, especially when using Glock models with mounted optics or lights.

Kydex holsters are made from molded thermoplastic and provide a rigid, precise fit. With adjustable retention screws, you can tighten or loosen the grip on your Glock 47 exactly how you prefer. Kydex handles moisture and sweat without damage, making it suitable for daily carry. It often features built-in optic cuts or light grooves, so holsters made from Kydex usually accommodate Glock 47 models with mounted accessories better than leather. This material typically costs between $50 and $120 depending on design and brand.

Hybrid holsters combine a leather or neoprene backing with a Kydex shell. The backing rests against your body, improving comfort and reducing sweat buildup, while the Kydex portion secures your Glock 47 firmly. This blend offers a good balance of comfort, retention, and accessory compatibility. Hybrids often come with adjustable clips or belts, allowing you to customize carry angles and height. These generally fall in the $70 to $130 price range. Hybrids do require some break-in, especially the leather or neoprene parts, but they adapt more quickly than all-leather options.

Retention plays a significant role in material choice. Level II and Level III duty holsters like the Rapid Force, often made from Kydex or polymer composites, offer active retention methods specifically engineered for models like the Glock 47. These holsters involve mechanical locks or thumb breaks that provide extra security during high-movement activities or law enforcement use. Leather or hybrid holsters usually don’t include such active retention features but can add retention straps or adjustable tension to improve security.

For Glock 47 variants equipped with optics or weapon lights, material choice impacts functionality. Leather holsters tend to have limited compatibility unless custom-molded with optic cuts. Kydex holsters are often designed with these accessories in mind, making it easier to find perfect fits that secure the firearm and hardware without increasing bulk. Hybrids can work well too but require a Kydex shell molded precisely for the optic or light profile. Adjustability in retention screws or straps also helps accommodate slight differences caused by accessories, ensuring the Glock 47 stays securely in place.

Making Sure Your Glock 17 Holster Fits Your Glock 47 Safely

Ensuring your Glock 47 fits safely in a Glock 17 holster requires careful retention testing and attention to draw and reholstering techniques. Begin by checking the holster’s retention adjustment if available. A properly adjusted retention keeps the firearm secure without making drawing difficult or unsafe. Retention that’s too loose risks accidental drops, while overly tight retention can cause fumbling during a draw.

To test retention, insert your Glock 47 into the holster and gently shake it vertically and horizontally. The gun should stay firmly in place without wobbling or slipping out. Next, perform several draw-and-reholster cycles in a controlled environment, focusing on smooth, deliberate movements. This practice helps you identify any retention weaknesses and allows you to build muscle memory for safe and efficient handling.

• Adjust retention screws or straps to achieve a snug fit with no movement.
• Conduct retention tests by shaking the holster with the gun inside.
• Practice slow draw and reholstering drills before live use.
• Test with different clothing or gear to assess real-world fit.
• Stop using the holster immediately if the gun slips out unexpectedly.

While many Glock 17 holsters fit the Glock 47 well because of similar frame dimensions, certain holsters might not account for slight differences in length or accessory configurations, such as with special lights or sights. Persistent retention problems or discomfort after adjustments suggest you should invest in a dedicated Glock 47 holster. Dedicated holsters are designed to match every contour and accessory position precisely, maximizing retention and draw speed. These holsters typically cost between $40 and $100 depending on material and brand, which is a modest price for improved safety and confidence during carry.

Draw and reholster safety matter most when mixing holsters between firearm models. Always keep your finger off the trigger until ready to shoot, and ensure your holster fully covers the trigger guard to prevent accidental discharge. Avoid rushing or forcing the firearm in or out during practice, as improper technique can cause wear on the holster or even injury. Routine inspection of the holster’s condition, retention screws, and fit helps maintain reliable performance. Any damage or looseness in the holster means you should replace it promptly.

Common Fit Issues Using Glock 47 in 17 Holsters and How to Fix Them

Fitting a Glock 17 holster to a Glock 47 can cause problems like loose hold or interference from mounted optics and lights. Adjusting the retention or altering the carry angle can often resolve these issues. If clearance or secure retention remains a problem, consider switching to a holster made especially for the Glock 47.

Retention Adjustment Techniques

Retention keeps your Glock secure in the holster, preventing accidental drops while allowing a smooth draw. Glock 17 holsters may have looser retention on a Glock 47 because of subtle size and frame shape differences. Start by tightening any adjustable screws or retention devices on the holster. Use a screwdriver to turn retention screws clockwise in small increments, testing fit after each turn until the Glock holds firmly but still draws easily.

Many holsters rely on friction or mechanical clips to retain the pistol. Ensure any hood or strap on your holster securely snaps over the slide or rear sights of your Glock 47. Adjust holster cant by loosening mounting screws and rotating the holster body up or down a few degrees to get better grip and access. Small cant changes (5 to 15 degrees) often improve comfort and retention.

Dealing with Optic or Light Clearance Problems

The Glock 47 MOS comes optics-ready from the factory, meaning red dots or lights will stick out beyond the profile a Glock 17 holster is designed for. A standard Glock 17 holster rarely clears mounted optics or rail lights well, causing binding or failure to seat fully. Holsters built for G47 optics or lights have added cutouts or raised channels to fit these accessories. To improve clearance:

• Choose holsters labeled “MOS compatible” or built for Glock 47 optics systems.
• Check for holster models with adjustable tension that allow some wiggle room for optics.
• Use a holster with a wider mouth or raised sight channel.
• Remove or swap out accessories for slimmer alternatives where possible.
• Consider a paddle holster if draw speed and quick removal are priorities.

Trying to force the Glock 47 with a mounted optic or light into a Glock 17 holster not designed for them risks holster and gun damage, plus unreliable retention.

Never force a Glock 47 optic-equipped pistol into a standard Glock 17 holster; expect a holster specifically designed for optics to ensure proper fit and safety.

When to Upgrade to a Custom Glock 47 Holster

Using a Glock 47 in standard Glock 17 holsters might work fine for some, but if retention adjustments and clearance tweaks don’t fully resolve fit problems, a custom or dedicated Glock 47 holster is the safest choice. Custom molds conform exactly to the G47’s frame, barrel length, and mounted accessories so retention, draw, and comfort are optimized. Consider upgrading if you notice any of the following:

• Persistent loose retention that can’t be tightened without making draws difficult.
• Holster doesn’t clear your mounted red dot or light, causing damage or incomplete seating.
• Discomfort from standard cant or holster shape despite adjustments.
• Using aftermarket accessories unique to the Glock 47 MOS that require special cutouts.
• Relying on your holster daily for carry with consistent performance demands.

Custom holsters generally cost $60 to $150 more than standard Glock 17 models but offer better long-term protection and faster, safer draws.
