A safety is a training wheel. Once you are used to depending on training wheels you can get complacent and accidents happen. When you think the trigger is safe...you lose. Whether the gun has a safety or not, the trigger is ALWAYS the LAST thing you touch only when you want to shoot the gun.
And IMO if you are going to carry a gun, ANY gun, cover the trigger when it is holstered/pocketed/concealed/not in use. Holsters with holes for your finger to go into the trigger guard, holsters that you slide the barrel of the gun over inside your pants...useless and dangerous. Get a trigger guard covering holster(a Mic style does fantastic) and you will never have to worry about a pocketed or tucked gun ADing. But keep sticking guns in pockets or waist bands with uncovered triggers long enough and, safety or no, you are going to have a bad day.
