It’s no secret the human body goes wild when it’s flooded with adrenaline. I act like a cool cucumber with the light’s on, and practice all the time, but when startled I lose a great deal of dexterity and memory.
GLOCK pistols are as simple as they come. The manual of arms is quick to learn, and the firearm has earned a great reputation for always going “bang” when you pull the trigger.
The tolerances in the parts make the GLOCK pistol very resilient to dirt or lack of lubrication. For the majority of us regular Joes, that’s not a bad thing.
