The Glock 28 was similar in respects to the subcompact Glock 26 and Glock 27 models though chambered to fire the .380 ACP cartridge ala the Glock 25. Also similar to the previous subcompact offerings was its use of a blowback operation firing action. Glock initially introduced the .380 ACP-firing pistols in an attempt to crack those foreign markets where standard military calibers were restricted from civilian use. As such, the low-recoil Glock 28 was manufactured to fill the void.
Introduced in 1997, the G28 somewhat lighter than the Glock 26 and Glock 27 before it. She sported the same time-tested durable exterior, accuracy and robustness that made Glock a household name. The pistol grip was ergonomically designed to fit comfortably in the hand while the magazine was inserted through its base. The trigger, requiring a 5.5lb pull, was set within a thick trigger guard which sported a forward finger rest for added control. Sights were located forward and aft along the upper portion of the slide. Overall length was 160mm (6.29 inches) while the barrel was 106mm (4.17 inches). Weight was just 18.66 ounces, lighter than that of the G26 and G27 models, with a loaded weight of 23.77 ounces.
While the Glock 28 made use of a standard 10-round magazine, it could also accept the optional 12-, 15-, 17- and 19-round magazines as well.
