The Glock 19, a compact 9mm pistol, has earned a legendary reputation for reliability and performance. Its popularity has led to several generations of improvements, each building upon the strengths of its predecessors. Understanding the differences between these generations is crucial for anyone considering purchasing a Glock 19, whether for self-defense, competition, or collection. This comprehensive guide explores the key distinctions between the various Glock 19 generations.
Glock 19 Gen 1 (1982-1988)
The original Glock 19, the Gen 1, marked a significant shift in handgun design. Its features, revolutionary for their time, included:
- Rough Texture: The Gen 1 featured a noticeably rougher frame texture compared to later generations. This provided a more aggressive grip, but some users found it abrasive.
- Simple Trigger: The trigger pull was relatively straightforward, lacking the refinements of subsequent generations. While reliable, it felt less refined than later models.
- No Rail: The Gen 1 lacked an accessory rail, limiting the ability to attach lights or lasers.
- Early Polymer: The polymer used in the frame was a slightly different formulation than what's used today, leading to some variations in durability reports from that era.
While Gen 1 Glocks are now considered collector's items, their parts compatibility is somewhat limited compared to later models.
Glock 19 Gen 2 (1988-1997)
The Glock 19 Gen 2 introduced several improvements based on user feedback and evolving technology:
- Improved Trigger: The trigger received minor refinements for a smoother pull.
- Finger Grooves: More pronounced finger grooves were added to the grip, enhancing ergonomics for some shooters. However, this became a point of contention as it didn't suit all hand sizes.
- No Rail (Still): The accessory rail remained absent, a key limitation for many users.
Glock 19 Gen 3 (1997-2010)
The Gen 3 marked a significant leap forward for the Glock 19:
- Accessory Rail: Finally, an accessory rail was incorporated, opening up possibilities for tactical lights, lasers, and other accessories. This remains a hugely popular feature.
- Improved Ergonomics: The finger grooves were either softened or completely removed in some variants, improving the suitability for a wider range of hand sizes.
- Ambidextrous Slide Stop Lever: An ambidextrous slide stop lever enhanced the versatility for left-handed shooters.
- Improved Barrel: Slight refinements were made to the barrel, improving accuracy for some users.
The Gen 3 remains a very popular and highly sought-after model.
Glock 19 Gen 4 (2010-2017)
The Gen 4 introduced even more user-focused enhancements:
- Modular Backstraps: Interchangeable backstraps allowed for a customized grip size and feel, catering to a wider variety of hand sizes and preferences.
- Enhanced Trigger: The trigger was further refined for an improved pull.
- Reduced Recoil: Minor changes in the recoil spring system resulted in a slightly softer recoil.
- Improved Texture: A new, more aggressive texturing was added to the grip, improving control.
Glock 19 Gen 5 (2017-Present)
The current generation, Gen 5, represents the pinnacle of Glock 19 evolution:
- Marksman Barrel: The inclusion of a Marksman barrel significantly enhances accuracy.
- Ambidextrous Slide Stop Lever (Improved): The ambidextrous slide stop lever received further refinements for better operation.
- Glock Marksman Barrel (GMB): This barrel contributes to better accuracy, especially at longer ranges.
- No Finger Grooves: Finger grooves are completely absent, offering a clean and customizable grip surface.
- Improved Trigger: Glock has continued to refine the trigger mechanism for an even smoother and more predictable pull.
- nDLC Finish: The nDLC (nitride) finish offers improved wear resistance and corrosion protection.
Choosing Your Glock 19 Generation
The best Glock 19 generation for you depends largely on personal preferences and intended use. If you prioritize budget and reliability, a Gen 3 or 4 might be excellent choices. If accuracy and modern features are paramount, the Gen 5 is hard to beat. Consider handling different generations if possible before making a purchase decision. This allows you to experience the ergonomics and trigger feel firsthand and make an informed choice. Remember to always prioritize safety and proper training regardless of the generation you choose.
