Is the 1911 SA cocked and locked more likely to go off than some other SA/DA? I'll accept the premise it could be. Most 1911's are larger full frame guns worn on outside the belt holsters. One specific trait it getting dropped during handling on the hammer - which is a problem even with lever guns and shotguns. Exposed hammer weapons in and of that specific design are more likely to go off when you smack them hammer first on a solid object.
Taking that off the table for a pocket carry gun - what happens when the slide is flipped off? First, pocket carry can be done with or without a holster - and nobody responsible is saying you can carry a cocked weapon with a live trigger with no holster. Further, nothing else should be in that pocket, either. That's why we saw the pic of the LCP in a holster for pocket carry. Having it bounce around loose in the pocket with a magazine would be less safe than a C&L 1911 style - you would at least have to get the safety off AND pull the trigger.
"What if" the safety does get swiped off? You still have to pull the trigger, have to ask what could cause both interactions in a pocket, especially if it's in a holster? If something could do that with a 1911 cocked and locked, why would it not be able to do the same with a live trigger with no safety at all?
It's really up to the carrier, tho. I had my objections in the day to the 1911 system, spent money to not have one, yet trained on them for years and carried them on duty, or it's similar descendants. Never had a problem - yet the live trigger, albeit with 8 pound pull, on the ones I did buy for myself still bothers me. I will feel more comfortable with having the hammer locked down, than having a trigger that isn't.
It's really not whether one is "better" than another - it's about your perception of risk and what you intend to do in the way of carry. Much the same as to whether you would prefer to have a magazine disconnect - where the push of the mag release also locks the action so that it cannot go off, regardless of a round being in the chamber and having it cocked. Some abhor it, other's thank the designer daily because they are here on earth because of it. A perp couldn't use the gun after winning the struggle to take it away from them - the owner pushed the mag release and it couldn't go off. The backup gun did, tho.
I don't think I particularly need a mag disconnect - but if it was a duty gun carried OWB for police work, I would certainly expect it and appreciate it. Same for "SAFE" action triggers or hammer safeties - they have a place, depends on the circumstances and what priority the user puts on them.
I don't thing anyone particularly wants a weapon in their pocket to go off - hence the large number of carriers using inside the waistband holsters. In either case, the safety shouldn't be easily flipped off anyway - if you have a 6 pound trigger, the safety should be the same, and in neither case should you carry in a way that would snag it. That is far more important because of the risk than whether you have one or both.
In that regard, 1911 cocked and locked is a bit more like belt and suspenders - it's more safe than a trigger alone. And that trigger doesn't have to be a 2 pound target trigger, either. Light triggers are for precision range work, street triggers are all about adrenaline dumps and the difficulty of reflexive reaction, unintentionally pulling the trigger because the hand was engaged in a gripping action with no fine motor control.
One other thought I just saw in a post - in Texas, the largest number of CCW applicants is over 50. When you are trained and experienced in a certain type of firearm due to military or duty requirements, you tend to stick to what you know when it comes to self defense. You choose what you are already familiar with, instead of something new and different. Plus, those of us over 50 are more than aware of the abuse we put our body to, plenty of us out there with carpal tunnel. A large double stack grip with or without heavy long pull trigger isn't a good choice. The ergonomics are against us. I, for one, now prefer, like it or not, a slim grip, and easily accessed controls I have practiced with for years and know how to operate.
That's not everybody, choose what you like, but choose what works best, instead of what some tacticool expert requires you to use so you can keep your man card. He won't be there to back you up - you will be on your own. He will just be around after the fact to critique something he hasn't witnessed, and he certainly will not have walked a mile in your shoes, either.
