Both ranges I frequent do not allow Conceal Carry and do not allow drawing from a holster ..

The out door range I was told was due to insurance reasons .. Don't
know if that is factual or just an excuse ..

The indoor range was due to a person firing a round into the floor next to someone else .. that ended drawing from a holster .. Owner states safety reasons ..

Shooting in my back yard I do practice holster drawing .. but usually don't allow anyone else to unless I am acquainted on how well the person shoots .. and how safe they are .. there are others I won't allow ..

But almost all of my holster drawing is done indoors dry firing with an unloaded pistol in my safe room !! often I will stick on a red dot to see any movement ..
