The Modular Optic System (MOS) and the newest Gen5 innovations are combined in the GLOCK 23 Gen5 MOS, a small.40 S&W handgun that offers users a highly customizable and adaptable option. This model features GLOCK's nDLC finish, which offers enhanced durability and toughness on both the barrel and slide. The GLOCK Marksman Barrel (GMB) in the Gen5 provides improved accuracy through new rifling, while the absence of finger grooves on the grip allows for a more natural and comfortable fit for various hand sizes. The ambidextrous slide stop lever caters to both right- and left-handed shooters, enhancing usability. Additionally, the flared mag-well aids in quicker reloads, crucial in high-pressure situations. The MOS configuration allows for the easy mounting of a wide range of red dot optics using interchangeable mounting plates, further enhancing the pistol's adaptability for tactical and competitive shooting scenarios. Overall, the GLOCK 23 Gen5 MOS is designed to offer superior performance, precision, and customization in a compact package.
