Yea the blue/black guns do have the advantage of being less observable in most situations. Thats one reason I gravitated to stainless finishes on my full size duty guns. I wanted the miscreant it was pointing at to be able to see it VERY CLEARLY. 
Off duty and on my own time I wanted something lighter and thin. Easy to carry. But with a good round in it. I don't have an "S" on my chest so my primary concern, on my own time, is to protect me and mine and be a good witness.
The 3914NL loaded with Ranger 147 grain RA9B enables me to do those things. And look good while doing them.
I don't recall who said it here, but I remember one member describing the blue finish applied to 3rd gen guns as; "....looks like some monkeys with sharpie markers applied the finish to the slide. About as durable too." Or words to that effect. Accurate description in my experience. It just doesn't hold up as well as other finishes.
But the 3914NL........well all the 39XX NL guns are just really perfectly designed for the task at hand. The single sided safety/decocker and slanted dust cover, combined with the thinness of the pistol and its overall size just make it a joy to conceal and carry. Better than the standard 39XX series guns, IMO.
Mine has actually usurped my much loved 4513TSW as my most often carried pistol. Regards 18DAI
