Don't blame the gun, blame the person. There's never been an occasion where a gun has gone off without a human present. If there was an ND with a Glock it was because the person involved was not sufficiently trained on that platform.

If you are not comfortable with carrying a semi-auto in condition 1, do not carry it. Train, train, train until you are as comfortable with it as you are with a revolver, which is in condition 1. You are doing yourself a dis-service in the level of protection you are providing yourself and your loved ones if you are not as ready as possible, both physically and mentally.

I am a revolver guy as well, but I've trained with a Glock, a 1911 and a PPK to the point that I can carry any of them in condition 1 and myself in yellow.
