The GLOCK 45 Gen5 MOS by Umarex is the perfect replica for those seeking the best of both worlds: it combines the maneuverability of the G19's compact slide with the solid grip and capacity of the G17's Full-Size frame. This "Crossover" configuration is among the most appreciated by modern operators.
The highlight of this model is the MOS (Modular Optic System): the CNC-machined aluminum slide is designed for mounting Red Dot optics (compatible with Docter, Trijicon, C-More, and Leupold footprints via adapter plates sold separately). Visually and to the touch, the replica is indistinguishable from the original, thanks to the deep matte black finish and the original Glock logos engraved.
On the field, the G45 Gen5 offers excellent performance: the gas system and innovative nozzle ensure a particularly strong and realistic blowback (recoil) effect. It is designed to handle high-pressure gas (up to 150 PSI), maintaining a constant power within 1 Joule. The trigger pull is crisp and realistic (breakpoint at approximately 2.8 kg), and the Hop-Up is adjustable for maximum precision.
The dimensions, faithful to the original (1:1 scale), ensure compatibility with dedicated hard holsters for real firearms.
Note: Adapter plates for mounting Red Dots are sold separately.
