For that matter I guess in the heat of the moment you could forget to pull the digitally manipulated primer ignition actuator, too. Or fumble the chemically powered high energy kinetic ballistic projectile projector and drop it. Or blank and forget you even have it on you. It's a well documented fact that humans make mistakes; no need to belabor that.
...
I find it highly unlikely that someone is going to forget to fire the gun when one's intention is to fire the gun, unlike manipulating a manual firing inhibitor which is an additional act required by addition of a device non essential for the firing function of the gun. But, since your asking, Ill answer.
Even if there is a danger of forgetting to pull a trigger, risk of not having a trigger outweighs having one, since you cannot frickin fire the gun without it.
Even if there is a danger of forgetting one even has a gun on him or her, risk of not having one outweighs having one, since you cannot frickin defend yourself without one.
You cannot defend yourself without a gun and the trigger on it. You can defend yourself without a manual firing inhibitor.
Does that help you comprehend the difference?
...
All that said, if the manual safety is so apt to get you killed there must be lots of examples of it happening. Can you share a few of them with us so we can get a sense of the scope of the problem?
Also, I understand the frustration of not doing so well in an argument, but can you please do without putting words in my mouth?
Where did I ever say manual firing inhibitor is "apt to get" me killed?
I stated that the risk associated with having one for me is higher than not having one. If I happen to have a 1911 when I have to defend myself, I'd rather use that than not have a gun. Actually I own 1911s.
Anyway, I will answer anyway, may be to your dismay.
Instructors like Rob Pincus actually challenges if anyone can finish his course without 1911 malfunctions or user error specifically regarding manual firing inhibitor manipulations. So, he must have seen it.
Gabe Suarez states he saw it, and also states it is not rare. If my opinion, which is not even saying it is wrong to use it, upsets you, then you might not want to ask him about what he thinks of it, since his answer would be even blunt than mine.
I have also seen it while in training.
If you find someone dead on a ditch with a pistol with a manual firing inhibitor engaged, how is anyone going to tell if the person failed to manipulate it or the person did not attempt to disengage it at all? If it happened to a cop and the cop survived, what incentive does he or she have for admitting it? Anyone can get ambushed, but admitting that one failed to react because of failure to manipulate a gun can mean adverse administrative action. So, what is the incentive?
Actually there was in incident where a cop could not fire when he intended to shoot which was posted on Officer.com. Lucky for the cop, it would have been an unjustifiable shoot. But, if it was, it could have lead to his demise.
I am still not saying it is wrong to use a gun with such device. But, since you're asking, there you go.
