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 10mm caliber pistol offers a robust platform for shooters seeking a powerful semi-automatic handgun. Its accuracy is commendable, delivering consistent performance at various ranges, making it suitable for both target shooting and field use. The ergonomic design, with adjustable grip options, accommodates a wide range of hand sizes, enhancing control and comfort during extended sessions. Reliability is a strong point, as it functions well under diverse conditions with minimal malfunctions when properly maintained. However, maintenance can be somewhat demanding, requiring regular attention to ensure optimal performance. Availability of certain replacement parts may pose challenges for some users, potentially leading to delays in repairs. The trigger pull is crisp, averaging around 5.5 pounds, though some may find it slightly heavy for rapid follow-up shots. Felt recoil is noticeable due to the potent cartridge, which could be a consideration for less experienced shooters.
