Glock 42 .380 ACP Ultra-Compact Pistol

The Slimline Specialist: Glock’s Entry into the Pocket Market 

The Glock 42, released in early 2014, was a landmark model for the company—it was their smallest pistol ever produced and their first true "Slimline" design. This specific unit, serial AATB348, belongs to the first year of production. Unlike previous Glocks that shared frames across calibers, the G42 was engineered from the ground up specifically for the .380 ACP cartridge. Despite its tiny footprint, it gained a reputation for having much milder recoil than its competitors due to its locked-breech design (uncommon for such small .380s). This unit features an added Hogue grip sleeve, a popular modification that addresses the G42’s very thin profile by adding palm swells and finger grooves, significantly improving purchase and control for shooters with larger hands.

Condition and Action Highlights

Action: Striker-fired "Safe Action" system; the slide is surprisingly easy to manipulate compared to other pocket pistols.

Ergonomics: Upgraded with a Hogue rubber grip sleeve, providing a more secure, cushioned hold and filling the palm.

Bore: 3.25-inch hexagonal rifled barrel in excellent condition; known for being very accurate for its size class.

Finish: Excellent condition; the gas-nitrided slide finish shows minimal to no holster wear or handling marks.

Frame: Subcompact polymer frame with the Gen 4-style texture (visible beneath the Hogue sleeve).

Magazines: Includes two factory 6-round single-stack magazines.

Sights: Standard Glock white-dot front and white-u-notch rear sights.
