I have a 1911 but don't carry it. I have not trained with one in a long time and I don't trust myself to remember to sweep off the safety in a pinch. If I change my mind about carrying the 1911 it will only be after a lot of re-training myself. I really don't see that happening.
Truth be told a 1911 could be carried safety off. I wouldn't personally do that or recommend the practice. I use a thumb over safety shooting style. My cocked and unlocked comment was made as a joke. I am trying to think of examples of guns with safeties or decockers that people wouldn't have to use. There are certainly some striker fired guns like the shield that the safety could be left off. CZs maybe, those come in so many configurations that surely they have an option for something like that. Walther P99 could be carried without de cocking.
