Glock G45 Gen5 MOS 9mm Pistol | 4.02" GMB Barrel | 17+1 | Streamlight TLR-1 HL Light, 3 Mags & Case
The Glock G45 Gen5 MOS combines the compact-length slide of the G19 with the full-size grip of the G17, giving shooters a balanced crossover platform that carries 17-round magazines without sacrificing handling. This example is factory-cut for optics, outfitted with Glock’s Marksman Barrel, and upgraded with a mounted Streamlight TLR-1 HL weapon light for instant low-light capability. Matched serial numbers on slide, frame, and barrel affirm its factory integrity, while the nDLC finish and ambidextrous controls reflect Gen5 refinements.

What's Included

Gen5 upgrades set this pistol apart. The nDLC-coated slide carries front and rear serrations plus a factory MOS interface that accepts popular micro red-dot footprints; only the cover plate is absent, so it is ready for optic installation.
The Glock Marksman Barrel features polygonal rifling and a recessed crown to enhance accuracy and resist wear. At 4.02 inches, it preserves sight radius while remaining compact for duty or concealed carry.
Controls are fully ambidextrous. The slide-stop levers are mirrored on both sides, and the magazine release is reversible, accommodating left- and right-handed shooters without modification.
An integral accessory rail hosts the included Streamlight TLR-1 HL. Delivering 1,000 lumens for up to 1.5 hours, this light adds a clear tactical advantage with a proven aluminum body and easy CR123A power.
A flared mag-well speeds reloads, while Gen5’s removal of finger grooves allows a neutral, consistent grip. Combined with the Safe-Action trigger at a 5.5-lb pull, the G45 offers familiar Glock reliability optimized for modern requirements.
