This full-size Gen5 MOS configuration brings the 10mm chambering together with modern Gen5 ergonomics. The frame deletes finger grooves and incorporates a flared and beveled magwell for efficient magazine changes while maintaining the Safe Action system.
The nDLC-finished slide and barrel provide a uniform, corrosion-resistant surface. Front and rear slide serrations aid manipulation, and the beveled slide nose eases holstering. The MOS cut arrives with the cover plate installed, ready to accept compatible optic plates if desired.
The Glock Marksman Barrel features enhanced rifling and a recessed crown. In this example, the bore presents with a mirror finish and well-defined polygonal rifling consistent with the GMB design.
