Notes
The G45 MOS has become the default choice for many U.S. law enforcement agencies adopting red dot sights on duty pistols. The crossover design is particularly suited to duty use: the compact slide makes holstering easier while the full-size grip provides maximum control and 17+1 capacity. The MOS cut adds minimal weight and maintains the same sight picture as the standard G45 when used with the cover plate. Compatible with Glock 17 magazines in 17, 19, 24, 31, and 33-round configurations. The French National Police adopted the G45 MOS variant for their nationwide service pistol contract.
Background
The G45 MOS became the go-to recommendation for law enforcement agencies making the transition to red dot-equipped duty pistols. Its crossover design solved a practical problem: the compact slide fit standard duty holsters more easily than the full-length G17 slide, while the full-size frame gave officers the grip they needed for maximum control under stress. When the French National Police selected the G45 for their nationwide contract, it validated the crossover concept on the world stage.
