The AmeriGlo Defoor GT-532 Glock 42/43 sights are purpose-built iron sights for shooters who depend on compact, concealable pistols for everyday carry. Named after firearms instructor Mike Defoor, this Range Series design strips away the unnecessary and focuses on what matters: a fast, repeatable sight picture under real conditions. If you carry a Glock 42, 43, 43X, or 48—or run one of those frames on an MOS slide—these sights give you the rudimentary but proven geometry that works when it counts.
The front sight features a 0.115-inch serrated blade designed to acquire targets quickly without the distractions of tritium or fiber. That narrow profile cuts through the rear notch cleanly, and the serration eliminates glare while giving your front sight texture to lock your eyes onto. The rear sight uses a square notch that's 0.15 inches wide—a width proven in competition and defensive training to balance speed and precision for most shooters. Both front and rear are case-hardened steel for durability that won't quit, even after years in a holster or heavy range use.
Compatibility is straightforward: these sights fit the slide dovetails on Glock 42, 43, 43X, and 48 pistols, and they work on MOS (Modular Optic System) slide variants if you're planning to co-witness a red dot. Whether you're fine-tuning a carry gun, setting up a backup sight configuration, or building your first Glock, the Defoor GT-532 delivers simplicity and reliability without compromise.
