Anytime laser grips come up, I can't understand the folks who start pounding on the table trying to convince everyone they should not be used, they are horrible, they will ruin your gun handling skills.
Most everyone I know who is running their CCW with them is doing so simply to give themselves even more of a chance of survival in a life/death situation.
Yes, iron sights are wonderful and everyone should train, train and train with them.
But...when the real deal happens, God forbid, I'm not going to be worried about anything other than stopping the threat.
Whatever I can use to improve my odds sounds good to me.
