For those discerning shooters who desired the smallest GLOCK possible, the company responded with the now popular G42 in 380 AUTO with ultra-compact dimensions and easy-to-shoot characteristics. The G42 packs all the features GLOCK customers have come to appreciate – from the GLOCK Safe Action® System with its multiple integrated safety features to the brand’s proven reliability and durability.


SLIMLINE DESIGN – developed for concealed carry


Safe Action® System

Three safeties disengage sequentially as the trigger is pulled and automatically reengage when the trigger is released.
Same trigger pull for each shot – short trigger reset.Learn more about the Safe Action® System

Surface refinement

The surface of the GLOCK slide and barrel is black and non reflective. All GLOCK metal parts are subject to a surface treatment making them corrosion and salt water resistant.

Polymer frame

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

Special grip texture

The slimline RTF was designed to enhance grip traction, without being too aggressive.

Reversible magazine catch

The magazine catch of the slimline frame is reversible and enlarged towards the rear of the pistol. For left and right handed users.

Magazine with extension

A magazine with extensions is available for securing the grip and better ergonomics.

Barrel profile

The polygonal barrel is easy to clean and its better bullet to barrel fit increases the velocity of the projectile.

Loaded chamber indicator

A visible and palpable indicator is located on the extractor.

Slide stop lever

A fully functional slide stop lever stops the slide in the rearward position after having fired the last round in the magazine.

Trigger distance

The trigger distance of the slimline pistols is reduced compared to other GLOCK models. The grip angle is equivalent to the larger pistols in the GLOCK lineup.

Standard GLOCK sights

The dimensions of the standard GLOCK rear sights were reduced to fit the slim slide.

Single stack magazine

The magazine of the GLOCK slimline pistols has a single stack design to reduce its dimensions to a minimum. The metal insert is covered by a polymer coating.
