Front serrations (FS)
To provide a different look and an additional tactile surface.

nDLC finish
GLOCK's nDLC provides tougher, more durable protection than previously used finish. The nDLC finish increases protection against corrosion and scratching and improves the ability of the pistol to function in adverse conditions.

Ambidextrous slide stop lever
The ambidextrous slide stop lever makes it easier for gun owners to quickly, safely and comfortable manipulate the slide wether they are left-handed or right-handed.

GLOCK Marksman barrel
The GLOCK Marksman barrel (GMB) features enhanced barrel rifling based on the proven polygonal barrel design which delivers improved accuracy.

Flared magwell for speedloading
The larger opening of the flared magwell makes it easier to funnel the magazine into the magwell, particulary in high-stress situations where fractions of a second matter.

Versatility by removal of the finger grooves
Comfortable grip to a wider range of consumers, regardless of their hand size.

Safe Action System
Three safeties disengage sequentially as the trigger is pulled and automatically reengage when the trigger is released.

Enlarged floor plate
The enlarged front of the floor plate makes it easier to pull the magazine free of the pistol if it doesn't fall free during malfunction or reload.

Safety advantage through orange follower
The orange follower allows the shooter to clearly see if there are any rounds left in the magazine or not.

Customizable frame size
Every GLOCK Gen5 comes with beavertail backstraps in two sizes. The backstrap frame allows the users to change the circumference of the grip to fit their individual hand size.

Gen4 RTF - Rough textured frame
The Gen4 proven rough textured frame surface is present on the Gen5 frame as well. It was designed to enhance grip traction, without beeing to aggressive.

Reversible magazine catch
The magazine catch of the Gen5 frame is reversible and enlarged towards the rear of the pistol. The reversible magazine catch is more user friendly to the shooter's reach and allows them to switch the catch to the left or right side of the pistol.

Mounting rail
Mounting rails in front of the trigger guard of all competition, standard, and compact frames allow mounting accessories such as tactical lights and lasers.

Polymer frame
The durable and lightweight polymer frame absorbs recoil due to the dampening characteristics of the polymer.

Loaded chamber indicator
Visible and palpable indicator as part of the extractor to show whether there is a cartridge in the chamber.
