GLOCK Modular Optic System Familiarization Course

Joseph Parent III

What is the GLOCK Modular Optic System (MOS)?

GLOCK engineers have developed the GLOCK Modular Optic System to simplify the mounting of popular optic sights, without the costly custom machining of the pistol’s slide.

Optical sights are popular in competitive shooting and are becoming increasingly popular for concealed carry, home defense and target shooters.

In this course you will learn:

  • The Fundamentals of Marksmanship and how to integrate the Modular Optic System into the shooting solution.
  • Presentation of the GLOCK MOS Pistol from the Holster
  • Firing of the GLOCK MOS pistols.

Students will be required to wear a sturdy belt capable of supporting the weight of a holstered pistol and magazines.
