I've gone back and forth on this issue and while I understand that the safety is really not necessary, I thought it was better to err on the side of having a safety. I think it can help prevent an accidental or negligent (depending on your point of view) discharge, especially when holstering the weapon. Of course, it would take additional practice to make sure disengaging the safety is an automatic action and yes, accidents can still happen as we can forget to engage the safety or do something extra stupid in a moment of stress. In the end, it is a personal preference thing. I decided that the safety gave me a bit of an edge and I am willing to practice and train with it. Now I have two safeties: One ambidextrous and one I cut down in case I decide to get a grip laser.
