1:1 Replica
The Umarex Glock 17 MOS air pistol is a licensed replica of the firearm version. This means that it looks, feels, and functions like the real thing, but at a more affordable price. Because it is an accurate representation, it should fit your holster and allow you to practice your draw stroke, aiming, and shooting.
Authentic Blowback Action
The slide moves back and forth with each shot to help simulate realistic blowback. This simulated recoil helps you train for follow-up shots as you regain sight picture. It doesn't recoil as strongly as the firearm version does, making it more manageable for newer shooters.
Red Dot Ready with MOS System
The Glock MOS System allows the operator to mount their choice of pistol red dot directly to the slide without further modification. This means that if your sidearm already has a red dot attached, you can install the same one for a more realistic training experience. It comes with four different plates to ensure a correct fit.
