Why are Glocks prone to negligent discharge? I own a Sig Sauer 9mm. and a S&W .357 but I've never owned or fired a Glock. I'm curious why people keep saying this.
My bet is that it was more the fault of the holster. I bet he was using a serpa retention holster. With this type of holster you have to push the release on the side of the holster as you pull the gun. It you continue pushing as the gun clears the holster the finger will go right into the trigger guard making it easy to accidentally pull the trigger and fire the gun. I imagine he was trained on how to properly use the holster but just screwed up.
It is because the Glock “safety” is embedded in the trigger mechanism itself. That means when holstering, if anything gets in the trigger guard, you can end up pulling the trigger. By anything, I mean not just your finger. It could be a fold of clothing or a drawstring from a wind-breaker. Hence if you don’t pay attention while holstering your Glock, you can get “Glock leg.
It is possible to do this with other pistols, but Glocks are ubiquitous now-a-days. It is possible, but more difficult to do this with a revolver due to a stronger (10-12 lbs) and longer trigger pull.

Most Glocks have a relatively light trigger pull. That with the and the lack of a user-controlled safety mechanism (other than the users’s brain), equals a the potential for negligent discharge.
