G23 Gen5 MOS

GLOCK’s compact 40 S&W, equivalent of the GLOCK 19 Gen5, puts controllable power into an ideally-sized package - substantial enough for police patrol, small enough for discreet and comfortable all-day concealed carry. It is the top choice for professionals who work undercover. 

With the release of the G23 Gen5 the newest generation GLOCK standard is now available in 40 S&W.

By applying the Gen5 technology this model comes with nDLC finish, a flared mag-well, the proven GLOCK Marksman barrel (GMB) and an ambidextrous slide stop lever. 

Adjustable like the Gen4 model the frame of the G23 Gen5 features the modular backstrap and beavertail system (MBS) and comes with a reversible magazine catch.

For simplified mounting of optical sights this model comes with 4 numbered GLOCK MOS Adapter plates.

Note: The slide width of the 40 S&W Gen5 models is slightly bigger compared to the previous generation. Please consider when choosing your holster.
