About the Gun

The Gen 4 series of Glock pistols were introduced in 2010. Like most new polymer framed pistols the Gen 4 series features interchangeable grip inserts. The Gen 4 series also incorporates a dual recoil spring assembly, a feature only in previous generations' compact models. Other features include a reversible magazine release, a Tenifer matte finish slide and new grip texture. Changes in the Gen 4 design are significant enough such that not all parts can be mixed and matched with previous Glock generations.

Analysis

This 9mm pistol is a well-regarded choice for competitive shooters and enthusiasts seeking precision and adaptability. Its extended barrel and slide enhance accuracy, particularly at longer ranges, making it a solid option for target shooting. The ergonomic grip design, with adjustable backstraps, accommodates a variety of hand sizes, ensuring comfort during extended use. Reliability is a key asset, with consistent performance even under demanding conditions. The trigger pull, averaging around 5.5 pounds, offers a crisp break, though some users may find it slightly heavy for rapid follow-up shots. Felt recoil is moderate, manageable for most shooters with proper technique. On the downside, maintenance can be somewhat involved due to the modular optic system, requiring careful attention to detail. Additionally, sourcing certain replacement parts may pose challenges, and the larger frame might not suit concealed carry preferences for some users.
