Identifying a Glock 27 Gen 4 requires a keen eye for detail. While many Glock models share similarities, the Gen 4 boasts specific features that set it apart. This guide will walk you through the key characteristics to help you confidently distinguish a Glock 27 Gen 4 from other Glock models and generations.
Key Features of the Glock 27 Gen 4
The Glock 27, a subcompact .40 S&W pistol, underwent significant changes with the introduction of the Gen 4. Here are the hallmark features that distinguish it:
1. The Gen 4 Frame: Enhanced Ergonomics and Interchangeable Backstraps
The most noticeable difference lies in the frame. The Glock 27 Gen 4 features:
- Interchangeable Backstraps: This allows for customized grip size and feel. You'll find multiple backstraps included with the pistol, typically small, medium, and large. This is a major distinguishing feature of Gen 4 Glocks.
- Textured Grip: The grip features a more aggressive texturing compared to previous generations, enhancing control and reducing slippage.
- Ambidextrous Magazine Release: Unlike earlier generations, the Gen 4 includes a reversible magazine release, accommodating both right- and left-handed shooters.
2. Enhanced Slide Features
While less immediately obvious than the frame changes, the slide also holds clues to the Gen 4 designation:
- Improved Slide Serrations: The slide serrations are often more pronounced and aggressive, providing a better grip during racking. The pattern itself may differ slightly from earlier generations, offering a more textured surface.
- Possibly a Rail on the Dust Cover: While not exclusive to Gen 4, the presence of a rail on the dust cover (under the barrel) is common in modern Glocks, including the 27 Gen 4. This allows for the attachment of tactical accessories like lights or lasers.
3. Markings and Serial Number Location
Subtle differences in markings can also help with identification:
- Gen 4 Marking: Look for a subtle "Gen4" marking somewhere on the pistol, often on the side of the frame. The exact location might vary slightly.
- Serial Number Location: The serial number location on the Gen 4 Glock 27 might be slightly different compared to earlier generations; while not a definitive identifier on its own, it's a point to note if comparing to other models.
Comparing the Glock 27 Gen 4 to Other Models
To ensure accurate identification, compare the suspected Glock 27 Gen 4 to images and descriptions of:
- Glock 27 Gen 3: Lacking the interchangeable backstraps and featuring a less aggressive grip texture.
- Other Glock Subcompacts: Distinguishing features include caliber (only .40 S&W for the 27) and magazine capacity (typically lower than full-size Glocks).
- Other Glock Generations: Focusing on the frame features detailed above will help differentiate Gen 4 from previous or subsequent generations.
