My Shield 45 has a safety. I am so used to safeties on my 1911's that anything else seems naked without one. I alternate CCW carry with it and my Kimber Ultra Carry II, and I don't want to have to think about which one it is when I draw.
It takes all of a nannosecond to draw, flick the safety off, and fire. I just like the feeling of an extra measure of safety while carrying.
They make 'em both ways for a reason!
