What Does a Gen 3 Glock 34 Come in: Complete Contents & Buying Guide

Wondering what does a Gen 3 Glock 34 come in? The package typically includes the handgun with its 5.31-inch barrel, two 17-round magazines, a cleaning brush, and a cable lock. It also comes with interchangeable backstraps featuring finger grooves, a factory-installed trigger, and the original box with manuals for easy setup and maintenance. Start by verifying the included magazines and accessories to ensure you have everything for safe and accurate use right out of the box.

What Comes Included with a Gen 3 Glock 34 Package

When you purchase a new Gen 3 Glock 34, the package includes several key items necessary to get started right away. The main component is, of course, the Gen 3 Glock 34 handgun itself. This model is chambered in 9mm and features a standard capacity magazine. Buyers receive two Glock 17 compatible magazines that hold 17 rounds each, offering the typical 17+1 rounds capacity. Getting two magazines allows you to practice quicker reloads and carry a loaded spare.

Along with the firearm and magazines, the package includes factory manuals that provide detailed information on operation, maintenance, and safety. These manuals are important for new owners to understand proper handling and care, contributing to safer and more reliable use. Some packages also feature a small factory tool, often a punch tool, which can assist with simple disassembly tasks like removing the slide or pins during cleaning. You won’t generally find extra accessories like holsters or sights included in the standard box.

• Gen 3 Glock 34 handgun, 9mm chambered
• Two 17-round Glock 17 compatible magazines
• Factory user manual and safety guide
• Basic factory tool for disassembly (punch tool)
• Plastic case for safe storage and transport

The included plastic case is sturdy enough for storage but is not intended for long-term heavy-duty use. This case ensures all the components stay together and helps protect the firearm when not in use or during transport. Factory magazines are interchangeable with other Glock 17 magazines, which can be helpful if you want to add higher capacity magazines later or use your existing Glock 17 magazines.

Receiving the factory manual and tool matters because it provides you with the official instructions and guidance from Glock, which supports safe ownership and proper maintenance. Avoid skipping the manual as Glock’s Gen 3 pistols have some design details, such as finger grooves on the grip and absence of the modular backstrap, that differ from later generations. Proper documentation can help avoid confusion. Factory magazines included meet the standard for 9mm rounds capacity, so you don’t need to buy extra magazines immediately unless you want extended capacity or specialty mags.

How to Identify a Genuine Gen 3 Glock 34

To identify a genuine Gen 3 Glock 34, focus on specific physical and technical traits that separate it from other Glock generations. The Gen 3 line, introduced in 1998, features distinct grip contours, a universal accessory rail, and unique slide markings. Recognizing these features ensures you confirm authenticity and avoid confusion with later or earlier models.

Slide Markings and Serial Numbers

The slide of a Gen 3 Glock 34 includes several important markings and the serial number which help verify its generation. Look for the model number “34” stamped clearly on the slide, along with “Glock” branding and the word “Austria” or the country of manufacture. Unlike Gen 4 or Gen 5 models, the Gen 3 slide does not have any numeric generation identifier; instead, you verify the generation by comparing the slide design to known Gen 3 traits.

The serial number on a Gen 3 Glock 34 is engraved on the slide and the frame, usually matching in sequence. The serial number format adheres to Glock’s standard style from the late 1990s through the 2000s. Authentic Gen 3 pistols generally have no additional markings such as “Gen4” or “Gen5” present on later models. The slide features a non-modular backstrap and a single recoil spring, distinguishing it from newer generations.

Grip Features and Finger Grooves

A defining visual trait of the Gen 3 Glock 34 is the presence of finger grooves on the front strap of the grip. These grooves are molded into the polymer frame to improve hold and control. Above the trigger guard on either side, you’ll also find thumb rests, which help with grip stability. The grip surface is textured but not as aggressively as the Gen 4’s rough texture, instead, it offers a reliable, medium-level grip suitable for competition and field use.

The backstrap on a Gen 3 Glock 34 is fixed rather than modular, so no interchangeable backstraps are available. This contrasts with Gen 4 and Gen 5 models, which offer modular or removable backstraps. Notably, the Gen 3 design retains the classic “pebble” texture in areas outside the finger grooves, differing from the checkered or more aggressive textures on later generations.

Magazine Release and Controls

The magazine release on a Gen 3 Glock 34 is extended compared to previous generations, making it easier to operate without shifting your grip. The release button is not reversible by default, but you can swap it from one side to the other with some effort. It is bulkier than typical Gen 1 or Gen 2 releases but less flared than the wider Gen 5 magwells.

The slide stop lever is longer than on classic Glock 17 models, providing improve control for competitive shooting. This lever is not ambidextrous as seen on Gen 5 models, so it will be positioned on the left side only. The single recoil spring system under the barrel also aligns with Gen 3 design, lacking the dual spring of Gen 4 and 5 pistols. Use these steps to verify a Gen 3 Glock 34:

1. Examine the slide for “Glock 34” model marking and confirm absence of “Gen4” or “Gen5” engravings.
2. Check the serial number location on the slide and frame to match standard Glock Gen 3 placement and format.
3. Check the front strap of the grip for finger grooves and look for thumb rests located above the trigger guard.
4. Feel the grip texture to ensure it matches rough but not excessively aggressive pattern typical of Gen 3.
5. Confirm the backstrap is fixed and not removable or modular.
6. Operate the magazine release to confirm its extended, non-ambi design consistent with Gen 3.
7. Verify the slide stop lever length and left-side-only placement.
8. Check internally for a single recoil spring guide rod system.

Be cautious of aftermarket modifications that can obscure authentic Gen 3 features; always compare multiple identifiers before concluding a Glock’s generation.

Key Specifications and Features of the Gen 3 Glock 34

The Gen 3 Glock 34 comes equipped with a 5.31-inch barrel and an extended sight radius that improve accuracy. It features a standard 9mm trigger without finger grooves or an extended magazine release. This model balances precision with a longer frame designed for competition shooting rather than concealed carry.

Barrel Length and Sight Radius

The Glock 34’s barrel length measures 5.31 inches, significantly longer than many other Glock pistols. This extension contributes to an overall length of 8.74 inches, lengthening the sight radius compared to standard models. A longer sight radius helps improve shot placement accuracy by providing a clearer alignment between the front and rear sights.

The longer barrel and extended sight radius make the Glock 34 well-suited for competitive and tactical use, where precision is key. However, this size increase can reduce concealability compared to more compact alternatives like the Glock 19 or 43X.

Trigger Details and Pull Weight

The Glock 34 Gen 3 uses the standard Glock trigger system typical of the third generation, featuring a consistent pull that supports reliable accuracy. The trigger has a flat-faced design with no finger grooves on the grip, contributing to a more universal fit for different hand sizes.

Unlike some later Glock models, the Gen 3 Glock 34 does not come with an extended magazine release. The trigger pull weight remains standard, which generally aids in maintaining smooth, controlled shots suitable for competition.

Magazine Capacity and Frame Size

The standard magazine capacity for the Gen 3 Glock 34 is 17 rounds of 9mm ammunition. This capacity provides ample firepower and aligns with full-sized Glock models commonly used in competitive shooting. The frame is larger to accommodate the extended barrel and magazine size, which also influences balance and handling.

The overall weight and length distribution in the Gen 3 Glock 34 promote control and stability when firing. This setup suits shooters prioritizing accuracy and control over compactness.

This specification set makes the Gen 3 Glock 34 a preferred choice for shooters who value precision through an extended barrel and sight radius without added frame modifications like finger grooves. The lack of an extended magazine release keeps the controls closer to the frame, which some users prefer for consistency in handling.

Comparison: Gen 3 Glock 34 vs Later Generations

The Gen 3 Glock 34 differs from the Gen 4 and Gen 5 models mainly in features, included parts, and compatibility. While the Gen 3 offers a straightforward design with the widest aftermarket support, the later generations introduced new internal components and refinements that influence what’s included and how parts work together. Understanding these distinctions helps you decide which generation suits your needs and what accessories or upgrades will fit.

Included Parts and Accessories

The original Gen 3 Glock 34 package is more basic compared to the Gen 4 and Gen 5 versions. Standard items like magazines, recoil springs, and backstraps typically come with all models, but the Gen 3 lacks some of the newer features the later generations include. For example, Gen 4 and Gen 5 Glock 34 packages often include interchangeable backstraps and improved recoil spring assemblies to improve ergonomics and reduce felt recoil, which are absent on Gen 3.

Gen 5 versions include multiple internal enhancements such as an improved trigger pull and changes to the trigger housing, ejector, firing pin safety, and trigger bar. These components are incompatible with previous generation models. Standard Gen 3 kits usually don’t provide these parts as replacements, although some third-party and upgraded kits may include them.

Ergonomic and Design Changes

Ergonomic upgrades impact what comes in packages and what you experience when handling the pistol. The Gen 3 Glock 34 uses a textured grip designed to maintain a firm hold, which remains a favorite for many shooters. Later versions, particularly the Gen 4, added interchangeable backstraps that let you customize grip size. The Gen 5 models further refined this with a slightly reshaped grip and a more consistent trigger pull, improving handling and shooting comfort.

Internally, Gen 5 introduced small but significant changes, like a different trigger housing and firing pin safety configuration, to smooth out the trigger break. These changes mean you can’t simply swap Gen 5 parts into a Gen 3 frame. This can affect your choice of upgrades and parts if you’re looking to improve ergonomics or performance.

Compatibility of Magazines and Holsters

Magazine compatibility is mostly consistent within the Glock 17 and 34 models, but internal changes in later generations prevent full interchangeability across all parts. For instance, Gen 2 magazines with full-metal lining feed properly in all following generations, including the Gen 3, Gen 4, and Gen 5. However, some trigger components and internal parts from Gen 5 will not fit Gen 3 frames.

Holster compatibility is more closely tied to frame and slide design than to the generation number alone. The Gen 3 Glock 34’s frame and slide have subtle differences compared to Gen 4 and Gen 5, and holsters designed specifically for Gen 3 may not fit Gen 4 or Gen 5 Glock 34’s perfectly, and vice versa. This is important when selecting carry gear or competition holsters, ensuring optimal fit and retention.

Choosing between generations depends on your preferences for customization and internal upgrades. The Gen 3 offers simplicity and broad aftermarket support, while Gen 4 and Gen 5 provide refinements that come with a higher price and some parts incompatibilities. Always check holster and magazine compatibility before purchasing accessories, especially if you’re mixing parts across generations.

Holster and Accessory Compatibility for Gen 3 Glock 34

The Gen 3 Glock 34 does not come with a holster included, so you’ll need to buy one separately. Because the Glock 34 features a longer slide and barrel, 5.5 inches compared to the standard 4.49-inch barrel on a Glock 17, the holster you choose should accommodate this extended length. Holsters designed for the standard Glock 17 or similar Gen 3 and Gen 4 models often fit the Glock 34, but those made specifically for Gen 5 or newer models usually won’t fit properly due to wider slides and different controls.

Holsters that work best for the longer slide of the Glock 34 tend to be outside-the-waistband (OWB) types, which offer quick draw capabilities often preferred in competitive shooting. Leather holsters can also adapt to both the firearm’s shape and your body for a comfortable, custom fit. Avoid tight-molded holsters designed for Gen 5 or Gen 6 models, since those slides are wider and have ambidextrous controls that may cause fitment and retention issues with a Gen 3 Glock 34.

Many aftermarket holster makers provide models with adjustable retention and mounting hardware, allowing them to fit across multiple Glock generations. These features can help accommodate small differences, but you should verify the fit before relying on the holster for competition or daily use. A misfit holster risks poor weapon retention or an awkward draw, which can be problematic when time is critical.

Always test your holster’s retention and draw speed with your actual Glock 34 before using it in a serious setting to ensure proper fit and security.

• Purchase holsters made for full-size Gen 3 or Gen 4 Glock models to ensure fit for the Gen 3 Glock 34
• Prioritize OWB holsters for quicker draws and to accommodate the longer slide
• Use leather holsters for a form-fitting, comfortable carry option
• Avoid holsters cut for Gen 5 or Gen 6 Glocks due to slide width and control differences
• Look for adjustable retention to fine-tune fit across older Glock generations
• Confirm manufacturer specifications and user reviews for Glock 34 compatibility

Holster compatibility also depends on how you plan to carry or compete. If concealment is not a priority, an OWB holster that exposes the longer slide is ideal. Custom leather holsters require broken-in time to mold perfectly to your firearm, which means a short break-in period but can improve comfort and retention. Investing around $40 to $100 for a quality holster is typical for competitive Glock 34 users.

Factory and Aftermarket Upgrades for the Gen 3 Glock 34

The Gen 3 Glock 34 generally comes with factory sights that can be either fixed or adjustable, though most models include an adjustable rear sight for increased accuracy. This feature allows shooters to fine-tune their point of aim, which is important for competitive shooting or precision target work. Optics-ready models, such as those designed to mount reflex sights, are more common in later Glock generations. The Gen 3 variants rarely come optics-ready out of the box, so adding a red dot typically requires slide milling or purchasing an aftermarket slide that’s pre-cut for optics.

Aftermarket upgrades are popular with the Gen 3 Glock 34 due to the platform’s deep support and the abundance of affordable parts. Many aftermarket components either improve performance or customize ergonomics and aesthetics. Because the Gen 3 is older, some parts are interchangeable with other Glock generations, but others are unique or require slight modifications. Common upgrades include sights, triggers, slide parts, and internal components.

• Fiber optic or tritium night sights for better visibility in low light
• Custom adjustable rear sights to replace or upgrade the factory sights
• Trigger kits to reduce pull weight and improve reset response
• Aftermarket slides, sometimes optics-ready, for mounting red dot sights without gunsmithing
• Extended magazines or baseplates for improved capacity and grip ergonomics
• Upgraded recoil springs and barrel options to improve reliability and accuracy
• Ergonomic grips, stippling, or grip tape for better control and comfort

To upgrade your Gen 3 Glock 34’s sights, start by choosing between fiber optic, tritium, or fully adjustable aftermarket sights. Installation usually requires a sight pusher tool or sending the pistol to a qualified gunsmith, which can cost $20 to $50. Higher-end sights range from $70 to $150 depending on materials and brand. A proper sight upgrade results in faster target acquisition and improved shot placement. Poor installation or incompatible sights can cause misalignment or damage.

Adding an optics-ready slide is a practical way to use a red dot with a Gen 3 Glock 34. You can purchase a pre-milled slide for around $200 to $300, then attach a compatible reflex sight, which typically costs $200 or more. Some older Gen 3 models may require custom fitting or modifications. Completing this upgrade will improve target speed and reduce sight acquisition time but involves additional cost and the need for professional installation if you lack the tools.

Maintaining and Caring for Your Gen 3 Glock 34 Package

Maintaining your Gen 3 Glock 34 and all its components is essential for reliability and longevity. The firearm’s strong slide finish resists rust, even in humid or saline conditions, but regular cleaning and care ensure consistent performance and safe operation. Focus on cleaning the barrel, slide, frame, and magazines, as well as checking sights for damage or alignment issues.

Start with a basic cleaning kit that includes a bore brush, cleaning patches, nylon or brass brushes, quality gun oil, and a lint-free cloth. Avoid harsh solvents that could degrade the polymer frame or finish. After each use or at least monthly if unused, disassemble the Glock 34 according to the manual and clean the barrel bore with a bore brush and solvent. Run dry patches through the barrel until they come out clean. Lightly oil the barrel and slide rails to reduce friction but wipe off excess to prevent attracting dirt.

• Clean magazines by removing followers and springs using a flat tool, then wipe inside the mag body to remove debris and residue
• Inspect sights visually and clean them gently with a soft cloth; avoid chemicals that could fog or degrade lens coatings
• Store the firearm and accessories in a cool, dry place with a dehumidifier or silica gel packs to prevent corrosion
• Regularly check for wear on springs, magazines, and the trigger system, replacing parts that show signs of damage or failure
• Use a duty or soft case that protects the Glock 34 from dust and moisture when transporting or storing

Magazine maintenance requires extra care. Dirt and residue buildup can cause feeding failures, so regularly disassemble and clean magazines. Springs may weaken with use, so replacing magazines every few years or after several thousand rounds is a good precaution. The polymer frame generally requires minimal attention but inspect it for cracks or unusual wear that could affect safety.

Pay attention to the condition of the sights because damaged or misaligned sights impact accuracy. Adjust them only with the recommended tools and method to avoid permanent damage. Proper storage avoids moisture and physical damage; aim for stable temperature environments around 65 to 75 °F to prevent condensation and material warping.

Typical Pricing and Purchase Options for a Gen 3 Glock 34

The Gen 3 Glock 34 generally sells between $600 and $700, depending on your local dealer and region. Pricing varies due to taxes, shipping, and dealer markups. Some dealers include extras like additional magazines or factory-installed upgrades which can affect the cost and value.

Dealers often offer purchase bundles that either include one or two extra magazines, night sights, or extended slides. These packages typically drive the price toward the upper end of the range. Opting for factory upgrades or holding out for bundles can save money over buying accessories separately later.

Check if the extra magazines included are genuine Glock mags, as aftermarket ones can vary in quality and reliability.

Prices also fluctuate based on whether the dealer is a large retailer or a local shop, with smaller shops sometimes charging more for added service or guarantees. Shipping costs can raise the final price if you order online. Comparing local offers and factoring in the extras helps ensure you find a deal that fits your needs and budget.
