The G40 Gen4 in MOS Configuration is chambered in 10 mm Auto and combines a long slide and barrel for improved velocity with a high magazine capacity. The Modular Back Strap design and the reversible magazine catch let you instantly customize its grip to adapt to accommodate any hand size. The MOS Configuration makes an easy job of mounting a reflex sight on the pistol’s slide without the need for a new slide or separate mounting system.


  • Gen4 Frame - RTF2 Grip with Finger Grooves and Interchangeable Backstraps (4 included) to ensure the best fit to your hand
  • Enlarged Reversible Magazine Catch - The magazine release catch of the Gen4 is reversible and enlarged, allowing you to easily switch the catch to the left or right side of the pistol with no additional parts.
  • Dual Recoil Spring Assembly - The Gen4 pistols have been upgraded to a dual recoil spring assembly. The dual recoil spring assembly noticeably reduces the recoil you feel, while simultaneously increasing its lifespan.
  • MOS - Modular Optic System makes it easier to mount optic sights on your GLOCK pistols. Optic sights are popular in competitive shooting and are becoming increasingly more popular for target shooting.  Includes 4 Optic Plates* (#00 Cover Plate, #01 Eotech/Doctor/Insight/Meopta05, #02 Trijicon RMR 06, #03 C-MORE 07, #04 Leupold Delta Point 08)
  • Safe Action System - Provides a consistent trigger pull from the first to the last round. The three automatic independently-operating mechanical safeties are built into the fire control system of the pistol.  This safe, simple, and fast system allows the user to concentrate fully on shooting without having any additional actions to disengage and reengage safeties. This means it is safe if it’s dropped, and additionally it functions at temperatures from -40° to 122° Fahrenheit.

*The G40 Gen4 MOS comes with Adapter-Set 02, and has slightly wider plates to accommodate the width of the G40 Gen4 MOS slide.
