With the G17 Gen 5 MOS FS GLOCK enhances the already near-perfect Gen 5 model of "The original" with the addition of the Modular Optic System (MOS). The slide is precision machined to provide a mounting system for popular optic sights. 

All of the Gen 5 qualities are present in this standard-size pistol: The latest GLOCK nDLC surface finish on the major metal components, unmatched in hardness and rust resistance; the high traction Gen 5 frame texture, quickly reversible magazine catch, ambidextrous slide stop lever, the GLOCK Modular Backstrap System (MBS) for individual operator adjustability, the universally-acclaimed GLOCK Safe Action®System and high visibility orange magazine followers. 

This model features a threaded (M13.5x1) barrel and includes Glock's Modular Optics System (or MOS) adaptor set.
