With the G19 Gen5 MOS GLOCK enhances the desirability of the already near-perfect Gen5 model with the addition of the Modular Optic System (MOS). The slide is precision machined to provide a mounting system for popular optic sights. With adapter plates, you can quickly and easily mount miniature electronic sights to the rear of the Gen5 GLOCK slide, which has front serrations for easier and quicker manipulations.

All of the Gen5 qualities are present in this compact-size pistol: The latest GLOCK nDLC surface finish, unmatched in hardness and rust resistance; the high traction Gen5 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.

Gen5 pistols feature over 20 design modifications from their Gen4 predecessors, including the GLOCK Marksman Barrel, nDLC finish, ambidextrous slide stop lever, the removal of finger grooves and a flared mag-well. These changes deliver improved accuracy, durability, performance, control, and flexibility whether you are on the range or in a situation where fractions of a second matter.

GLOCK pistols in standard MOS configuration now come with a single MOS adapter plate. The adapter plate included will fit the following: Trijicon®, Ameriglo®, and Holosun® (except 509). If your selected optic is not compatible with any of the above, additional adapter plates are available separately.

  • Flared mag-well has a larger funnel for faster, smoother reloads, particularly in high-stress situations where fractions of seconds matter.
  • GLOCK Marksman Barrel (GMB) features a more aggressive polygonal rifling with a target-style crown and tighter chamber specs, which delivers improved accuracy.
  • Ambidextrous slide stop levers offer increased ergonomics for left-hand shooters and shooting with the support hand.
  • Removal of the finger grooves on the grip allowed for superior grip ergonomics and improved fit for various size hands.
  • Firing pin safety and trigger spring enhancements enable the trigger housing to endure long term durability and result in a smoother trigger pull and improved trigger reset.
  • Safe Action® System safeties disengage sequentially as the trigger is pulled and automatically reengage when the trigger is released.
  • Enlarged Floor Plate makes it easier to pull the magazine free of the pistol if it doesn't fall free during a malfunction or reload.
  • Customizable Frame Size with backstraps in two sizes with beavertail. The multiple backstrap frame allows the users to change the circumference of the grip to fit their individual hand size.
