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 pistol in 357 SIG caliber offers a compelling option for shooters seeking a balance of power and control. Its accuracy is noteworthy, delivering consistent performance at various ranges, while the ergonomic design facilitates a comfortable grip for most hand sizes, aided by customizable backstraps. Reliability is a key asset, with a proven track record in diverse conditions, making it suitable for both duty and personal defense. The trigger pull, averaging around 5.5 pounds, provides a smooth and predictable break, though some may find it slightly heavy for rapid follow-up shots. Felt recoil is manageable but can be sharp due to the potent cartridge, potentially challenging for newer shooters. On the downside, maintenance requires attention to detail, and parts availability may be limited compared to more common calibers. This can pose issues for users in remote areas or those seeking quick repairs.
