Quite frankly, there is no philosophy or arguing to it.
It begins and ends with rule #3. Period. Anyone who makes any claims, arguments, or rebuttals otherwise should not own, carry, nor handle firearms. Ever. Period.
Barring mechanical failures, guns do not fire unless the trigger is pulled. Here's where rule #3 comes in. In a big way.
Glocks, nor any other gun, most certainly do NOT have problems with ND's. It is negligent owners/operators that have NDs. Guns do not. Guns are perfectly safe left sitting alone. They only fire when someone else comes into contact with them, be they human, or in a recent case, a dog.
Why would you think open/concealed carry matters? As long as the trigger guard is covered, the gun is safe while in the holster.
Sorry if I sound harsh, but this issue has been beaten to death, and frankly I'm quite tired of it. Glocks are not some "mythical beast" that will discharge when they feel like it. It's all about rule #3.
There's a lot to be said for Rule #3.
Welcome to TFL!!!
Did I mention rule #3 yet?
