The Umarex GLOCK 17 Gen5 MOS 4.5mm CO₂ BB Air Pistol is an officially licensed replica of the renowned GLOCK 17 Gen5 handgun. Designed to replicate the handling and appearance of the real firearm, this air pistol offers excellent realism and reliable performance for airgun enthusiasts.

Powered by a 12-gram CO₂ cartridge, the pistol fires 4.5mm (.177) steel BBs with a muzzle velocity of approximately 115 m/s (377 fps) and an energy level below 3.0 Joules, making it suitable for recreational shooting and target practice.

The pistol features an 18-round drop-free magazine that houses both the BBs and the CO₂ cartridge, allowing smooth feeding and fast follow-up shots.

This Gen5 MOS model includes a blowback slide system that cycles with each shot, providing realistic recoil and authentic shooting feedback. The Modular Optic System (MOS) allows compatible red-dot sights to be mounted using adapter plates, giving shooters additional aiming options.

Built with a metal slide and durable polymer frame, the pistol maintains a realistic weight and ergonomic grip similar to the real GLOCK design. A Weaver/Picatinny accessory rail beneath the barrel allows the attachment of tactical lights or lasers.

Combining authentic GLOCK styling, reliable CO₂ performance, and realistic blowback action, the Umarex GLOCK 17 Gen5 MOS is ideal for airgun training, target shooting, and collectors who want a realistic BB pistol.
