There are a few concerns about leaving them cocked 24/7, but it can't be too much of an issue, otherwise few people would opt for one. Revolvers are also not something that's very easy to sort out if they develop a fault during firing, unlike a self loader (generally).
One other good reason to use a pistol is they are easy to fit a torch/flash light to.
Depends a lot on quality. I doubt you would have many issues with Sig, H&K or Beretta; they all do D/A pistols and a few can probably have stress triggers fitted, so it would be unlikely to ND.
I don't like S/A pistols much for safety. A lot of people do manage to carry them cocked without incident, but D/A is definitely an improvement on them.
More modern self loaders are relatively safe, and a lot have a de-cocker to prevent the hammer slipping when manually dropped.
