Amen brother,In order for a safety to not be a danger to you in the event of a shootout you need to practice drawing the firearm, disabling the safety and then not putting your finger on the trigger until it is time to shoot. You've added an extra step to you draw time. What if the advancing bad guy only needed that extra half second to get ahold of you or better yet they don't have the extra step?
A safety is an add-on for someone who is not comfortable with their firearm, whether it be due to insufficient training, practice or an inherent flaw in the design of the gun.
I carry a glock 20 daily with a round in the chamber. The only time I have ever been even relatively close to a ng was testing the 'safeties' on a Walther p99c at the range. Yes I have seen safeties fail. Just as I've seen abs brakes cause accidents.
You should control the gun, not the other way around.
