But seriously. Maybe have the pistol checked to see if the sear on it is out of spec. Maybe it got bumped to half or full **** and just her handling it caused the hammer to release. Otherwise, see above.
Even if the sear is completely messed up, a modern DA, SA/DA revolver from any reputable manufacturer would not allow the hammer to hit firing pin (or FP to hit the primer) unless the trigger is pulled. And that is true even if it is cocked. And it is true even if the revolver has the FP on the hammer.

But it is the same for S&W Ruger, etc.
If your's does not, then it should not be a weapon kept loaded.
p.s. for the same reason a modern revolver will not "go off" when you drop it.
