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 compact .40 S&W pistol offers a solid balance of performance and concealability, making it a viable option for both duty and personal defense. Its accuracy is commendable for a subcompact design, delivering consistent groupings at typical self-defense ranges. The ergonomic grip, with adjustable backstraps, accommodates a variety of hand sizes, enhancing comfort and control during extended use. Reliability is a strong suit, with a proven track record of functioning under diverse conditions with minimal malfunctions. However, the trigger pull, averaging around 5.5 pounds, may feel somewhat gritty to users accustomed to smoother mechanisms, potentially affecting precision for some shooters. Felt recoil is noticeable due to the lightweight frame and powerful caliber, which could challenge less experienced users. Maintenance is straightforward, though sourcing certain replacement parts can occasionally be cumbersome, requiring patience or specialized vendors for repairs.

Equip this pistol with a finger extension and it becomes an 11+ 1 or a 13+ 1 without increasing the size beyond what one can carry in the front pocket of a pair of cargo pants or a pair of loose fitting jeans.
