Analysis

The Glock 45 MOS combines the concealability advantages of a compact slide with the control and capacity of a full-size frame. The MOS slide preparation uses the traditional adapter-plate system for mounting optics. This configuration served as the optics-ready crossover 9 mm offering prior to the introduction of the V-series and Gen6 platforms. It is distinct from the later G45 V (with internal geometry changes) and the G45 Gen6 (with RTF6 texture, flat-faced trigger, extended beavertail, and factory-integrated Optic Ready System).
