I understand why someone would be upset by the way the gun is setting in the holster, but the problem for me doesn't arise with it in the holster, it happens when the owner of the gun goes to pull it out and unload it so he can make it safe for the person complaining. With those types of holsters he will almost invariabley cross someone with the barrel. The point is that I have never known or heard of a gun going off by itself when it is at rest in holster, in fact I've never heard of a gun firing just sitting all by itself. I've only heard of guns going off when they were in someone's hand.
Rebellion dogs my every step!
