Glock G45 Gen5 MOS 9mm Pistol 17rd 4.02" Barrel Compact Frame

The Glock G45 Gen5 MOS combines the proven reliability of Glock engineering with modern optics-ready capabilities for serious shooters. This pistol features the compact frame of the G19 paired with the full-size slide of the G17, creating an optimal balance of concealability and performance.

What Makes This Different

The MOS (Modular Optic System) configuration eliminates the need for custom machining to mount red dot sights. Factory-installed mounting plates accommodate popular optics from Trijicon, Leupold, Vortex, and other manufacturers. The serrated steel slide reduces glare while providing enhanced grip for press checks and malfunction clearances.

Key Features

• MOS optics-ready slide with multiple mounting plate options
• 17+1 capacity with standard Glock magazines
• 4.02-inch GMB (Glock Marksman Barrel) for improved accuracy
• Ambidextrous slide stop levers for left and right-handed shooters
• Picatinny accessory rail for lights and laser attachments

• Reversible magazine catch for ambidextrous operation

Field testing demonstrates consistent accuracy and reliability across various ammunition weights and manufacturers. The improved barrel design delivers tighter groups compared to previous generations, while the enhanced trigger system provides crisp break and positive reset. Law enforcement agencies and competitive shooters have adopted this configuration for duty and match use due to its versatility and proven track record.
