Originally introduced with the Glock 22 (.40 caliber), and the Glock 17 (9×19) models, Glock's newest generation pistol, the Gen4, brings  design changes to one of the most popular handguns in the world.  New to the Gen4 family for 2011, Glock has unveiled Glock models 26 (9×19), G27 (.40 caliber) Gen4 models.


With any Gen4 model, Glock said the the most noticeable difference is that the basic grip size is smaller compared to the previous generation designs, due to the fact that the new generation offers a multiple backstrap system that allows the user to change the circumference of the grip to fit their individual hand size. The grip, which has a new Rough Textured Frame (RTF) surface designed to enhance grip traction, offers three options: a short frame version, medium frame or large frame that are easily changed and secured with a single pin. The trigger mechanism housing has also been dimensionally adapted to fit in the smaller sized grip space.


The magazine release catches are also significantly enlarged and reversible for the left handed shooter. To utilize the swappable magazine release feature, the Gen4 magazines have two notches cut on both sides of the magazine body, allowing users to switch access of the catch to the left or right side of the pistol with no additional parts.
Internally, the original recoil spring has been replaced with a dual recoil spring assembly, which noticeably reduces the recoil while simultaneously increasing the life cycle of the part. The slide and barrel shelf have been resized due to the larger diameter of the spring assembly. The front portion of the polymer frame under the slide has also been widened and enlarged internally in order to accommodate the dual assembly.


“GLOCK, Inc.'s dedication to perfection has made GLOCK the chosen firearm for many Law Enforcement agencies around the world.” said Gary Fletcher, Vice President at GLOCK, Inc. “The new Gen4 models are just another step in GLOCK, Inc.'s commitment to producing the best firearm for U.S. Law Enforcement, Military and the law-abiding citizen.”


The Gen4, just like any GLOCK pistol, has the same tested “Safe Action” system, durable exterior finish, cold hammer forged barrel, durability, reliability and lightweight that have made GLOCK firearms famous. All GLOCK pistols are backed by the GLOCK Limited Lifetime Warranty and world-class customer service and support that is second to none in the firearms industry.
