How this slide mounts an opticGLOCK's Gen6 replaces MOS: the standard-frame G17, G19 and G45 come with three polymer plates (02, 03, 04), and the optic screws directly into the slide through the plate, with no metal plate in between. GLOCK's sheet gives the thread by plate and no torque, and says to use the optic maker's own screws and directions.
