Glock G42 Slimline .380 ACP Micro-Compact Pistol – USA-Made, 3.25" Barrel, 6+1 Capacity
The Glock G42 is notable for being the very first and smallest pistol Glock ever produced. Built in Smyrna, Georgia, this USA-marked Slimline model pairs Glock’s proven Safe-Action reliability with a truly pocket-sized footprint. Its locked-breech design, uncommon in many .380 pocket pistols, delivers manageable recoil in an ultra-slim package—making this example attractive to both collectors of early Slimline variants and anyone seeking a discreet, dependable carry gun.

What’s Included
- Glock factory hard plastic pistol case (black)

Introduced at SHOT Show 2014, the G42 launched Glock’s Slimline architecture that later evolved into the G43, G43X, and G48 series. Collectors appreciate this early run for its role in that lineage and its “USA” proof mark confirming domestic production.
The pistol’s 3.25-inch gas-nitrided steel barrel uses Glock’s hexagonal rifling for excellent seal and longevity. Paired with the matte-black slide featuring rear serrations, the finish resists corrosion and wear while maintaining Glock’s understated aesthetic.
A 5.5-lb Safe-Action trigger with an integral safety tab, three internal safeties, and a reversible magazine release provide familiar Glock handling in a micro frame. Gen4-style micro-stippled grip panels offer positive control without added bulk.
Despite its 0.98-inch width, the locked-breech system keeps recoil soft compared to typical blowback .380 designs. The fixed polymer sights—white-dot front and white-outline U-notch rear—deliver a clear sight picture in a compact profile.
Three factory magazines are included, giving the buyer a full 18 rounds on hand before reloading—an uncommon bonus for a pistol in this size class.
