Glock 26 Gen4 The GLOCK 26 Gen4, in 9x19, introduces revolutionary design changes to the "BABY GLOCK"-the most sought-after concealed carry option since its release in 1994. The Modular Back Strap design lets you instantly customize its grip to adapt to an individual shooter's hand size. The surface of the G26 Gen4's frame employs the new scientifically designed, real-world-tested, Gen4 rough textured technology. Internally, the new GLOCK dual recoil spring assembly substantially increases the life of the system. A reversible enlarged magazine catch, changeable in seconds, accommodates left or right-handed operators.
