Truly mechanically induced accidents are nevertheless exceptionally rare. The guns only fire when the trigger is pulled, which is why gun owners stress the importance of trigger discipline.
All the more reason you follow the 4 rules of gun safety to a T with that brand. Especially the part about ensuring its not pointed anywhere it shouldn't be and unloaded check about a million times. (note, I own no firearms but have enough friends that do I gain a ton of knowledge on them.)
One exception to firearms going off on their own might be a misfire after trigger pull. That means you have a possibly live round in the chamber that could go off at any time. Need to be really careful on that one.
I will never willingly carry a striker fired weapon: no external hammer, so if something, like a windbreaker tie or finger catches on the trigger, you can't DTRT with your thumb on the nonexistent hammer to stop it from firing.
Flip side is what one of my instructors called manual safeties: "death levers". If you forget to flick it to safe....
Another side is that manual safeties make guns somewhat "proprietary" as Massad Ayoob puts it. Some police officers have avoided bad outcomes when their weapons were grabbed, as the criminal struggled to make it fire they could take effective action. Not so much of an issue for those who carry concealed.
"Exceptionally rare" events that send you to the hospital should be minimized if you are acting rationally. Choosing an "unpopular" gun with a safety vs. a "popular" gun with a safety...well, that isn't giving up the gun now is it?
That is why I have an issue with gun enthusiasts. They don't think and they literally get people killed/injured because of it. Then go "well its rare..."
So fucking what. Cars have a ton of safety features to reduce fatalities too even tho such fatalities are "rare".
If gun owners continue to show poor judgement when they have time to think about it rationally, why should I think they'll do any better under pressure?
