The Glock 43 is the original single-stack slim 9mm Glock, featuring a 3.41-inch barrel and 6-round flush magazine with optional 8-round extended. Introduced as Glock's first single-stack 9mm after years of customer requests for a slim carry option. The G43's slimness — 1.02 inches wide — makes it one of the thinnest carry 9mm pistols from a major manufacturer. Largely supplanted by the G43X for shooters wanting more capacity. Type: Pistol Action: Striker-Fired Caliber: 9mm Capacity: 6 Year introduced: 2015, Austria Weight: 17.95 oz Overall length: 6.26" Status: Active Intended use: carry
