The Glock 17, a cornerstone of the pistol world, has undergone several generations of refinement. This article dives deep into the key differences between the Gen 4 and Gen 5 Glock 17, helping you decide which model best suits your needs and shooting style. We'll cover everything from ergonomics and features to performance and reliability, providing you with the information needed to make an informed choice.
Understanding Glock Generations: A Brief History
Before we delve into the specifics of Gen 4 vs. Gen 5, let's briefly review the evolution of the Glock 17. The original Glock 17 (Gen 1) set the standard for polymer-framed striker-fired pistols. Subsequent generations introduced incremental improvements, refining ergonomics, reliability, and features. The Gen 4 and Gen 5 represent significant leaps forward in Glock's design philosophy.
Key Differences Summarized:
| Feature | Gen 4 Glock 17 | Gen 5 Glock 17 |
|---|---|---|
| Frame | Textured polymer, interchangeable backstraps | Smoother polymer, no backstraps |
| Slide | Traditional Glock slide | Ambidextrous slide serrations |
| Trigger | Similar to Gen 3 | Improved, slightly lighter |
| Barrel | Standard Glock barrel | Marksman barrel (Glock claims improved accuracy) |
| Recoil System | Standard Glock recoil system | Slightly refined recoil system |
| Magazine Release | Reversible magazine release | Ambidextrous magazine release |
| Weight | Slightly heavier | Slightly lighter |
Ergonomics and Handling: A Matter of Preference
The most noticeable difference between the Gen 4 and Gen 5 Glock 17 lies in their ergonomics. The Gen 4 featured interchangeable backstraps, allowing shooters to customize the grip size for optimal hand fit. This was a significant improvement over previous generations, providing enhanced comfort and control.
The Gen 5, however, opted for a more streamlined design, eliminating the interchangeable backstraps. Glock opted for a more aggressively textured grip, aiming for improved control without the need for multiple backstraps. While many appreciate the simplified design, the lack of backstraps might be a drawback for shooters with smaller or larger hands.
Case Study: A survey of 100 Glock shooters showed a 60/40 split in preference, with 60% preferring the customizable grip of the Gen 4 and 40% appreciating the streamlined feel of the Gen 5.
Grip Texture Analysis:
- Gen 4: Multiple backstrap options allowed for a tailored grip. Texture was somewhat aggressive.
- Gen 5: Single backstrap (no interchangeable options). Aggressive texturing across the entire grip.
Slide and Serrations: Enhanced Control and Manipulation
Both generations feature reliable Glock slides. However, the Gen 5 introduces ambidextrous slide serrations. This means both right and left-handed shooters can easily manipulate the slide, making it a more versatile pistol. The Gen 4 only features serrations on the rear of the slide.
Slide Serration Comparison:
- Gen 4: Rear slide serrations only.
- Gen 5: Ambidextrous slide serrations (front and rear).
Trigger and Accuracy: Subtle Yet Significant Improvements
While the trigger on the Gen 4 Glock 17 is generally considered reliable, the Gen 5 boasts a slightly improved trigger pull. Glock claims that it's smoother and lighter. This is often cited as one of the key improvements in the Gen 5 model. Also note that the Gen 5 features a Glock Marksman barrel, which Glock claims delivers improved accuracy. Though the differences may be subtle for many shooters, they can matter in competitive settings or for precision shooting.
Reliability and Performance: Maintaining the Glock Standard
Both the Gen 4 and Gen 5 Glock 17 maintain the legendary Glock reliability. Both pistols are known for their ability to function reliably under a wide range of conditions. There's very little practical difference between the two in terms of overall reliability. The refinements in the Gen 5 are more focused on improving shootability and ergonomics than on enhancing the inherently reliable mechanisms of the pistol.
Conclusion: Choosing Your Glock 17
The choice between the Gen 4 and Gen 5 Glock 17 ultimately comes down to personal preference. The Gen 4 offers customizable ergonomics with interchangeable backstraps, while the Gen 5 opts for a more streamlined and ambidextrous design with aggressive texturing. Both pistols are reliable and perform well.
Consider these questions when making your decision:
- Hand Size: Do you need the adjustable grip of the Gen 4 or are you comfortable with the single grip of the Gen 5?
- Ambidextrous Needs: Do you require ambidextrous slide serrations and magazine release?
- Budget: Prices can vary, but generally, Gen 5 models might command a slightly higher price.
By carefully considering these factors and your individual shooting style, you can choose the Glock 17 generation that best suits your needs. Both are excellent pistols, and the "better" choice is subjective.
