Yep, I carry a Kahr P40 and don't give a second thought to it's lack of a "mechanical" safety. Of course, it's got passive safeties so it doesn't go boom if it's dropped.
If you feel less than confident about it, buy a Fobus or Kydex holster for it, and you'll feel a lot better... At least I did. You realize pretty quickly that with all that plastic or other composite material surrounding the pistol, that trigger is in NO danger of being pulled.
Of course, Leather works too, but plastic is 100% un-flexible.
I wouldn't feel completely comfortable with one carried in an Uncle Mike's felt IWB... you can almost pull the trigger with the gun in the holster.
