I totally agree with this, and I know and understand that. This guy has no one to blame but himself he was stupid. The truth is the type of gun was a factor and this specific accident wouldn't have happened with a traditional DA/SA or 1911 with a manual safety engaged. It also doesn't mean that he still would be safe carrying a P92F without a holster (assumed this was how he had it) SOB, and wrestling with his Kid. The safety between his ears was disengaged.
I am a believer in thumb safeties, that doesn't mean that strikers can't be carried safely. But I do believe that it is important that we all recognize that certain types of accidents simply would not happen with weapons that have manually operated safeties. In safety speak, recognizing a hazard is the first step in making something safe.
