Glock 42 Slimline .380 ACP Micro-Compact Semi-Auto Pistol – 3.25" Barrel, 6+1, USA-Made
The Glock 42 is Glock’s first pocket-sized pistol, introduced in 2014 to deliver familiar Glock reliability in an ultra-concealable package. Built in the United States, this Slimline model combines a glass-fiber-reinforced polymer frame with a matte-black slide and hexagonal-rifled 3.25-inch barrel. Its micro size, 6-round single-stack magazine, and Safe Action system make it a straightforward defensive companion or collectible example of the design that paved the way for the later Glock 43 and 48.

This USA-manufactured Glock 42 carries the Pentagon proof mark and “USA” slide marking, underscoring its domestic production that avoids the 1968 GCA import-point limits on .380 handguns.
The Slimline frame measures barely over an inch wide, making the pistol easy to conceal without sacrificing Glock’s familiar grip angle and control placement. Rear slide serrations aid manipulation, while fixed white-dot front and white-outline rear sights provide a clear sight picture.
Inside, the 3.25-inch barrel uses Glock’s hexagonal rifling and a 1:9.84" right-hand twist to stabilize .380 ACP projectiles. The bore is bright and sharp, matching the pistol’s overall excellent condition.
A 5.5-lb Safe Action trigger, integral trigger safety lever, and internal safeties deliver the same striker-fired feel longtime Glock owners expect. Serial markings on slide and frame match, confirming this example’s original factory pairing.
With its micro-compact footprint, proven reliability, and role as the first of Glock’s Slimline series, this Glock 42 offers both practical carry performance and collector interest.
