IWB, chambered. If you have a quality holster and a quality pistol, there is no fear of the trigger getting pulled. I would recommend a good gun belt though (I really like Daltech Force biobelts, personally) My wife requests that I carry when we are out with our children, so I have been wearing an IWB CYA kydex holster with my G43 (used to be my G19, very happy for the smaller pistol!!!) and no issues. I can run around at the park, carry the kids, roll around on the ground with the dog and the pistol/holster stay secure. The only issue that I have is my shirt riding up over my gun though, I'm 6-04.
If you ever need your gun, the time it takes to chamber a round might be too much. That video of the off-duty Brazilian officer is insane... she stands in front of him and racks a round. If he had even been mildly paying attention to her, he could have shot her long before she got a round chambered. Thankfully he was distracted. I pray that I never need any of my guns, but I prepare to use them as quickly as I can.
