The Glock G19 Gen6 is a compact striker-fired 9mm built for concealed carry and home defense. Glock launched the sixth generation in January 2026. Its grip has a palm swell, a textured thumb rest, an enlarged beavertail and an undercut trigger guard, which together change where the hand sits on a compact Glock.

It holds 15 rounds on a 4.02-inch barrel, in a footprint unchanged for two decades, and it weighs 22.58 oz with an empty magazine. Three optic plates come in the set and screw into the slide, with the optic screwing into the plate, so nothing stacks underneath the dot. The trigger face is flat and breaks at 5.8 lbs, the RTF6 texture now covers the thumb rest as well as the grip, and a raised border round the slide stop lever keeps a thumb from riding it down. There is no manual safety, just three passive internal safeties that release in sequence as the trigger moves.

If you're cross-shopping, the Glock G19 V is the same size with no optic system listed and weighs 1.05 oz more, but it adds a flared magazine well and a cutout at the front of the frame for faster reloads. The Glock G19 Gen5 MOS is the previous optics-ready compact at 23.81 oz, and it keeps the Gen5 grip with the dot sitting on an adapter plate above the slide.
