GLOCK 20 Gen5 MOS | 10MM | 4.6 in | 15rd | UA205S203MOS

The GLOCK 20 Gen5 MOS is a full-size, optics-ready 10mm semi-automatic pistol built on Glock’s Gen5 platform. It pairs a Glock Marksman Barrel (GMB) and MOS slide cut with a polymer frame that includes a Picatinny rail and removable backstraps for a tailored grip. The pistol ships with three 15-round magazines and a factory accessory kit. A compact red-dot such as the Holosun 507K (priced well under $1,000) is a suitable optic choice for this MOS-equipped slide for durable, low-profile sighting on a full-size service pistol.

Common uses for this pistol include range and target shooting and hunting or wilderness backup where the 10mm cartridge’s performance is desired. The description and specifications below reflect only the data supplied for this listing.
