Glock 21 V MOS .45 ACP Pistol, 4.61" Ported Barrel, Black Cerakote, Optics ReadyThe ported Glock 21 V MOS brings a specialized performance treatment to the full-size .45 ACP platform. A 4.61-inch ported barrel, matching slide porting, black Cerakote, and fiber-optic sights give this handgun a distinct configuration for shooters who want more from their range pistol. The MOS interface adds optic flexibility, while the polymer frame and striker-fired action retain the familiar character of the G21.The defining upgrades are already part of the handgun: barrel and slide porting, a custom black finish, and an optics-ready sighting platform. Together, they create a purposeful setup that puts recoil management, visibility, and a clean tactical appearance at the forefront. It is a focused choice for a .45 ACP enthusiast building a serious practice and range setup.Choose the ported Glock 21 V MOS at ARMSAGORA's retailers for a full-size .45 ACP with distinctive custom features and MOS versatility.4.61-Inch Ported Barrel and SlideThe 4.61-inch barrel features porting paired with openings in the slide. Barrel ports vent propellant gas as the pistol fires, a design intended to help manage muzzle rise and support sight recovery. This is functional porting in the barrel and slide, giving the G21 a performance-oriented configuration as well as a recognizable appearance.For a shooter evaluating a ported handgun, the practical attraction is how that configuration feels during repeated range strings. The effect varies with ammunition, grip, and individual technique. The 4.61-inch barrel length remains a central part of this full-size pistol's identity.Black Cerakote and Full-Size Polymer FrameBlack Cerakote gives the customized G21 a unified, understated finish. It complements the ported slide and keeps the visual treatment purposeful. The dark exterior works well with the pistol's service-size proportions and lets the porting stand out without a contrasting color scheme.The polymer frame offers the full-size gripping area that draws many shooters to the Glock 21. Hand fit matters when selecting a .45 ACP pistol for regular use, and this configuration provides substantial grip space beneath the slide. Its appeal comes from the combination of that established format with the added barrel and slide treatment.Fiber-Optic Sights and MOS Optic CompatibilityFiber-optic sights provide a visible aiming reference in suitable ambient light. They give the pistol a useful sighting feature from the start, while the Glock Modular Optic System provides an additional path for a compatible red dot. That combination makes the ported G21 an adaptable platform for different sight preferences.The MOS system uses an adapter interface. Choose the correct plate for the selected optic and confirm the mounting hardware for that combination. Optics readiness does not mean every red dot fits the same plate. A red dot is not included, and co-witness height depends on the optic, plate, and sight arrangement.Familiar Action with a Specialized ConfigurationThe Glock 21 V MOS uses a striker-fired Safe Action mechanism in a semi-automatic .45 ACP handgun. This provides the operating format many Glock owners already know, paired here with custom porting and Cerakote. The barrel treatment and sighting options give the pistol a clear identity for range-focused enthusiasts.Holster selection should account for the exact handgun and any chosen optic or accessory. A holster described only as fitting a generic full-size pistol may not accommodate the same slide, sight, and attachment combination. Matching those details helps complete a setup built around the features that make this G21 distinctive.Configuration HighlightsGlock 21 V MOS full-size .45 ACP platform.4.61-inch ported barrel with matching slide porting.Black Cerakote custom finish.Fiber-optic sights.Glock MOS optics-ready interface.Product SpecificationsManufacturer: GlockModel: 21 V MOS PortedManufacturer Part Number: UV2150203MOS MODPTBLKProduct Code: UV2150203MOS_MODPTBLKUPC: 757106327196Type: Full-size semi-automatic pistolAction: Striker-fired Safe ActionCaliber: .45 ACP / .45 AutoBarrel Length: 4.61 inchesBarrel and Slide: PortedFrame: PolymerCustom Finish: Black CerakoteSights: Fiber opticOptics Interface: Glock MOS adapter systemFrequently Asked QuestionsAre both the barrel and slide ported?Yes.
