Glock 23 Gen4 .40 S&W Compact Semi-Automatic Pistol – 4.02" Barrel, 10+1
The Glock 23 Gen4 delivers .40 S&W power in a compact, duty-ready package. This Austrian-made pistol pairs a 4.02-inch barrel with the Gen4 dual-nested recoil spring assembly for reduced felt recoil and longer component life. An enlarged, reversible magazine release and modular backstrap system let shooters tailor the grip and controls to their preference, while the Safe Action trigger provides the familiar 5.5-lb break Glock users expect.

This Gen4 example features the updated dual-nested recoil spring assembly, a key Gen4 enhancement that softens recoil impulse and improves component longevity. The compact frame accepts both 10-round magazines and full-size Glock 22 magazines, offering flexible capacity options.
The glass-fiber-reinforced polymer frame keeps weight low while providing integral accessory rails for lights or lasers. An enlarged, reversible magazine release allows quick, intuitive reloads for right- or left-handed shooters.
Fixed 3-dot polymer sights come standard, with a white-dot front and white-outline rear for fast sight alignment. Austrian proof marks on the slide and barrel confirm origin and quality control.
The integral, serial-matched slide, barrel, and frame set underscores Glock’s manufacturing consistency, while the matte black nDLC slide finish resists corrosion and wear.
