Don't put gun on hook on door...I know of this happening with the result of a glock doing a pin wheel as it kept firing  
 
 
Someone mentioned the hammock inside the pants....uh got a joke about that, won't say it here.
I carry IWB in a nice holster that is secured to my belt using leather loops with snaps.  Gun is retained in the holster and will not fall out.  If in multi service stall, don't let pants drop below the bottom of the stall wall, gun rests firmly against side of leg right below knee.
Never have I taken gun off to take care of business, and if I did, the whole holser would come off.  Reholstering a weapon is an oppertunity for the trigger to get pulled.  The more the gun can stay in the holster, the better.
