Training can't put you in a life threatening situation, only prepare you. There are also times where you may physically be in an odd position, or be unable to fully compress the grip, and always the possibility of the system not properly releasing. I'm not saying this could happen all the time, but the potential is there. I'm fine with the dual stage trigger ala Glock. Less likely to be an issue IMO.
I agree, but what I'm saying is that a manual safety shouldn't impede your ability in any way. You train to pull and drop the safetly... it's automatic. This is how I think about it:
quickly grab anything.. a coke can, a remote... anything. Tell me what your booger finger does. I'll pretty much guarantee that your trigger finger grasps the object along with the rest of your fingers.
Now, let's say you find yourself in a struggle. Somebody is either just about on you or already on you and you're trying to pull your weapon. I know that your finger will get to the trigger. I've seen it over and over again in training courses with training handguns. Inevitably, the finger finds the trigger in the natural, albeit stressed and paniced grasp. That's not at all what you want to happend as you try to draw your handgun.
Training however can help... not guarantee, but help you prepare. It's easier to train to do something extra vs. not doing something that comes natural. Practicing to drop the safety is something that can easily become second nature... much like your finger always find the trigger.
I'm not suggesting this line of thinking is best, absolute, or what should be, etc.. It's just what works for me. I'm always concerned that the manufacturers tout these safety features and they're parrotted by gun oweners who probably haven't taken any training whatsoever and don't even know what any given particular safety device is even protecting you from. I have a neighbor and friend, one is a supervisor in the county sherriff's dept, the other is a commander in the FDLE. Over the years we've talked about this very thing... (and I'm sure you've seend the video of the officer shooting himself in the leg with his Glock while giving a speech to a classfroom full of kids) ... that accidental discharges are more common with Glocks, M&P's, and XD's more so than revolvers, DA pistols, or even 1911's carried cocked and locked.
Eveyone has to decide what works best. My only concern is that most people probably never bother to even take a single training or defense course to even know what options are out there and what would work best or not at all for them. Mine is just one example that has served me well.
