Glock 19XV MOS Threaded Barrel 19+1

Glock 19XV MOS Threaded Barrel

The Glock 19XV MOS Threaded Barrel is the crossover pistol for the shooter who refuses to choose between suppressor capability, optic flexibility, and full-size capacity.

Glock built the 19XV on the proven 19X platform — combining the full-size G17 frame with the compact G19 slide — and then pushed it further with three upgrades that matter: a factory-threaded 4.52″ Glock Marksman Barrel at 1/2×28, an MOS-cut slide for direct red dot mounting, and Ameriglo blacked-out tall sights that clear both suppressors and optics without adjustment. Furthermore, the coyote-colored slide carries Glock’s nPVD coating for corrosion resistance, and the frame accepts interchangeable backstraps so the grip fits your hand rather than forcing you to adapt.

Because this is a Davidson’s Exclusive, you won’t find this specific configuration at every Glock dealer — the factory-threaded barrel with MOS slide and suppressor-height Ameriglo sights as a complete package distinguishes the 19XV MOS from the standard 19X V lineup. The pistol ships with three magazines: one 17-round flush and two 19-round extended, plus a matching coyote-colored case, magazine loader, and cleaning rod and brush.

Key Features — Glock 19XV MOS Threaded Barrel

• 4.52″ factory-threaded Glock Marksman Barrel with 1/2×28 thread pitch — suppressor-ready from the box
• MOS (Modular Optic System) slide cut accepts adapter plates for Trijicon RMR/SRO, Holosun 507/407/EPS, Leupold DeltaPoint Pro, and others (MOS plates sold separately)
• Ameriglo blacked-out tall suppressor-height sights — front and rear — for clear sight picture over a can or optic
• G17 full-size frame paired with G19 compact slide — the original 19X “crossover” configuration
• 19+1 capacity with 19-round extended magazines; also ships with one 17-round standard magazine
• Coyote Brown nPVD-coated slide for enhanced corrosion resistance
• Interchangeable backstraps for customized grip fit
• Reversible magazine catch and ambidextrous slide stop levers
• Integrated equipment rail for weapon lights and accessories
• Glock Safe Action striker-fired system with three passive, independent safeties
• Includes: three magazines (1×17-round, 2×19-round), coyote-colored case, magazine loader, cleaning rod and brush
• Davidson’s Exclusive configuration — factory-complete suppressor and optic integration

Why This Product Stands Out

The 19XV MOS earns its keep because it eliminates the aftermarket compromise that suppressor-ready shooters typically face. Additionally, most pistols require either a threaded barrel swap or an aftermarket optic cut — here, Glock ships the complete solution from the factory, at a price that undercuts building the same capability piecemeal. Because the Glock Marksman Barrel is already the most accurate barrel Glock produces, the threaded variant delivers that same precision while adding the 1/2×28 thread pitch standard to the 9mm suppressor market.

The MOS system is where the 19XV MOS separates itself from older Glock optic solutions. Instead of a fixed-cut slide locked to one footprint, MOS accepts interchangeable adapter plates — so when you upgrade your red dot, the pistol adapts rather than requiring a new cut. Moreover, the Ameriglo blacked-out tall sights are co-witnessed correctly with most suppressor-height sight standards, which means you get a functional iron sight picture even when a can is mounted.

Beyond the hardware, the 19XV MOS inherits the full-size G17 frame — which means 17-round flush capacity and 19-round extended capacity without any grip extension or basepads. For home defense, duty carry, or range use where concealment isn’t the primary concern, that grip size translates directly to faster, more controlled shooting. The reversible magazine catch and ambidextrous slide stop also make the pistol genuinely left-hand capable without modification.

Ideal Use Cases

• Home defense — full-size grip, 19+1 capacity, suppressor-ready for reduced noise signature
• Duty carry / range training — large-capacity crossover platform with optic and light rail
• Suppressor host — factory 1/2×28 threaded barrel eliminates barrel swaps, compatible with the majority of 9mm cans
• Competition / range use — MOS optic compatibility for red dot integration without custom machining
• Davidson’s Exclusive gift/collector — limited-configuration factory package not available through standard distribution

Technical Specifications

Compatibility Information

Optic Compatibility (MOS) Because the MOS slide uses adapter plates rather than a fixed footprint, verified compatible red dot families include Trijicon RMR/SRO, Holosun 507/407/EPS series, Leupold DeltaPoint Pro, and others — note that MOS plates are not included and must be purchased separately. Consult Glock’s current MOS adapter plate list for footprint confirmation on your specific optic.

Suppressor Compatibility Furthermore, the 1/2×28 thread pitch on the factory barrel is the standard for 9mm suppressors, making this pistol compatible with the overwhelming majority of 9mm cans on the market. The Ameriglo blacked-out tall sights are configured at suppressor height for co-witness with a mounted can.

Magazine Compatibility The full-size G17 frame accepts both standard 17-round and 19-round double-stack magazines. Because the 19XV MOS ships with three magazines — one 17-round and two 19-round — magazine availability is wide, and both capacities are standard Glock G17/G19X pattern mags.

Rail / Accessory Compatibility The integrated equipment rail is compatible with Picatinny/MIL-STD-1913 rail-mount lights and lasers.

Holster Fitment The 19XV uses the G19 slide profile with a G17-length frame. Holsters cut for the G19X crossover platform are the correct starting point; confirm rail and threaded barrel clearance with your specific holster manufacturer before ordering.
