Glock G21 V MOS | .45 ACP | 4.61in | UV2150203MOS

The Glock G21 V MOS is a full-size, optics-ready semi-automatic pistol chambered in .45 ACP and built on Glock’s polymer frame. It features a 4.61-inch barrel, a serrated slide machined for the Modular Optics System, and a black nDLC finish for corrosion resistance. The package includes three 13-round magazines and is configured for right- and left-handed operation with a reversible magazine catch and ambidextrous slide stop levers.

A compact red-dot such as a Trijicon RMR Type 2 pairs well with the MOS footprint and remains under $1,000 for most configurations; adapter plates for common micro red dots are supported. Typical applications for this handgun include precision range training and duty/service use where a full-size, heavy-caliber platform is preferred.
