The Umarex Glock 19 Gen5 MOS CO2 4.5mm BB air pistol (SKU: 5.8460) is an officially licensed airgun featuring the Modular Optic System (MOS) cut on the slide, enabling quick installation of micro red dot sights. Combining the compact size of the Gen5 GLOCK 19 frame with an energy output under 2.0 Joules, this 4.5 mm (.177) steel BB pistol is designed for versatile target practice and dynamic recreational shooting.

Engineered with a heavy metal slide and a Gen5 textured polymer frame, the GLOCK 19 Gen5 MOS replicates the exact ergonomics of the firearm original, including the elimination of finger grooves and enhanced grip texturing. Powered by a standard 12-gram CO2 capsule housed inside the 16-round steel BB magazine, it delivers consistent shot velocity and accurate target engagement. Features include a lower Weaver/Picatinny rail, white dot sights, an automatic trigger safety, and an additional manual safety switch.
