Technology
FEATURES
Front serrations (FS)
Front serrations provide a different look and an additional tactile surface.
nDLC finish on barrel and slide
GLOCK's nDLC finish 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 comfortably manipulate the slide whether 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.
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.

Reversible magazine catch
The magazine catch of the 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.
Flared mag-well for speedloading
The larger opening of the flared mag-well makes it easier to funnel the magazine into the mag-well, particularly in high-stress situations where fractions of seconds matter.
Customizable frame size
The GLOCK G45 comes with backstraps in two sizes each one with or without beaver tail. The multiple backstrap frame allows the users to change the circumference of the grip to fit their individual hand size.
Magazine capacity
The G45 comes with two standard (17rds) magazines. Extended (17+2 rds) and other high capacity magazines are available.
Note: some magazines might not be available in all countries due to legal regulations.

Customize your frame size
The G45 allows the user to change the circumference of the grip to fit the individual hand size and comes with two sizes of backstraps in two different shapes. The backstraps are easily changed and secured to the frame with a single pin offering the following options: a short frame (SF) version, a medium (M) and a large (L) version.
The medium and the large version can be chosen with or without beavertail, the beavertail backstraps keeping large hands clear of the slide.
The short frame (SF) version without any backstrap mounted still remains a complete fully functional frame. Its dimensions are smaller than the G17 frame of previous generations.
