The Glock DOES have a safety. The little lever right there inside the trigger. And it's carried at the half cock - the trigger just finishes the last part of the loading.
The real difference SA vs SAFE action is that you don't have the longer trigger travel and higher weight. For some, it's not really about "safety," we've carried both and they are. It's about having a lighter trigger, or more importantly, a shorter one. Age and intrinsic ability to simple pull a trigger causes some people to prefer a much shorter travel. It's the normal younger guy with good hands who can enjoy a longer trigger and then discard the safety.
In a pistol like the LCP, the travel is the safety. It takes a lot of stroke. That is also the major complaint about it over the years - it's got a long travel, and the weight isn't low.
That creates an age and ability situation - I don't hear of carpal tunnel sufferers preferring a long heavy trigger and trying to make points about how safeties are dangerous. They aren't - of the three things that cause issues, ammo, mags, and then, the user, that last is largely why there are ND's and malfunctions.
Blaming the safety for user ineptitude is pretty lame. Considering that both styles have been on the market and issued weapons for all sorts of LEO's and the military side by side for over one hundred years.
There's no real predominance of one being particularly more dangerous than the other. Just when someone associates it with their persona and then makes it a statement of how they think they rank as a shooter.
"I use/don't use a safety and it makes be a better shooter than you. Genuflection, please."
Having or not having a safety isn't a make or break issue with being a successful firearms user. Not having unintentional discharges is, for one factor. Both do well, both have their recorded instances.
Which ever you choose, work at not being the next, and it's all good. As for the advantage in combat, it doesn't exist except in the minds of those to whom it makes a difference. Both work, both have failed - again, it's the user, not the gun.
When the user if forced to move from one type to the other, guess what? After proficiency is gained, the record shows there's no higher incidence of issues one from the other. Both are designed to be used by the human hand, get used to it - program the mind - they work.
Those who ask which is better aren't down the road of firearms use to know. Both are good, it depends on who you are and where you are on your journey in life. Don't be blind to the fact that as you age, you will have to make adjustments, and just maybe, you will be forced to switch sides.
The professional shooters have no issue with it, they win with both.
