I've evolved from decades of 1911's in several flavors and carried them confidently cocked and locked.
Now my needs and habits have evolved from DA/SA (a 5906 for 25 years, though I rarely carried it) then several DA/SA 3g's 3913LS & 3914NL to a 4040PD still a favorite for carry. I've also adopted AISW carry and cocked and locked in that position is a bit unnerving.
But now I've come to like DAO for carry as one less thing to be wrong when you really need it. Decocker only would be OK to, but I don't have one.
I've got a 6946, 4046 and a 4546 in DAO, but my very favorite carry semi-auto is a 3914 DAO. Thin, light, and has a double strike capability that is unusual in DAO Smiths.
Big Dot sights are also my favorite for carry as well a disabled magazine safety.
