G23 refers to the Glock 23, a compact .40 S&W striker-fired pistol known for reliability and a 13-round standard capacity. It works with G23-specific parts: slides (standard/MOS), .40 S&W barrels (standard or threaded 9/16×24; some use 1/2×28 with adapters), recoil spring assemblies, Gen-specific frames, trigger kits, sights, slide plates, and magazines. Compatible accessories include weapon lights, red dots (with MOS or plates), and compensators; 9mm conversion barrels and mags can enable caliber conversion. Ideal for duty, defense, and training.
