I see a lot of negativism toward any type of safety features. Safety, LCI, Magazine Disconnect, etc. People seem to feel the weapon won't work properly until they get rid of them. I've read statements that say they remove all safety devices even before they clean it.
It's a lot like the seatbelt resistance in the 70s.
"They wrinkle my clothes"
"I can't get out in an accident"
"The baby doesn't like them"
etc.
Our brain is absolutely the primary safety device. But a wise man also has Plan B, Plan C, etc. Also, a safety is intended to protect against others who may not be as safety minded as us.
The trigger safety on a Glock is not a safety. The gun will fire when you pull he trigger with or without it. At least with a dedicated safety the gun won't fire if my friend or wife picks it up and pulls the trigger. Hey, the gun wih no safety may be pointed at me.
Sorry; but at least I got it off my chest.
