Glock 31 Gen4 Pistol, .357 SIG, 4.48in barrel

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 reversable 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.
