A quality retention holster + that HKPC likely never having handled or holstered/unholstered a firearm makes the risk from her grabbing at it fairly low [not that it justifies it or alleviates it as an issue].Situational awaness!! It pays to be alert anywhere even at home. Good job not adding fuel to the fire, Imight have not been so nice to someone physicaly tring to draw my gun away..
I can't say how I'd handle somebody grabbing for my weapon to make a point for certain... They'd probably very quickly find themselves moving backwards away from me without the ability to stop such movement for at least a couple of feet if I was unable to distance myself. [I.e. if I cannot move away, I would ensure that they did.]
