I feel that I should add I open the action everytime I need to drop the hammers after not shooting. I had one instance where I held a hammer and pulled the wrong trigger, with the gun open it was simply a dryfire, not a negligent discharge.

As far as walking with the hammers back I can't see why moving in on a point with the barrels pointed skyward would be an issue. Could this be an instance of a safety feature (mechanical safety) creating sloppy behavior (poor muzzle control)?
