Glock is one of the most dominant pistol manufacturers in the world today. This weapon is preferred by countless police departments, government agencies, military units, professional shooters, competitors, and civilian users. Glock pistols are so widespread that the brand name is used synonymously with “pistol” in many countries.
There are currently more than 40 Glock models in production. Unless you have a specific interest in Glock, it is not easy to distinguish these models at first glance. Most have a similar design, a structure containing the same controls, and a similar handling feel. The main differences between the models are usually the type of ammunition they use and the frame/barrel dimensions.
In this article, I will explain all the pistol models Glock produces today, grouping them by their calibers.
