Just picked up one of those 4003 Atlanta Police guns. I inadvertently picked out a left hand model. Is this one of those that can be swapped over to the other side easily? Actually I think I am beginning to favor the release as it is. With a right hand model, I find I have to shift the gun in my hand to be able to push the release button. With the left, I simply move my trigger finger down and push from the right side. Thinking of adding a 4006 and would like them both to be the same. Tks
