I just finished this one up the other day.
It's set up with an optional magwell and two sets of grips.
Rear sight is a modified 'Tier One' of my manufacture.
Front sight is my 'Whiteball' design.
Finish is Graphite Black Cerakote applied over a base of manganese phosphate.
Here is a pic of the front sight illuminated by a very tiny flicker of camera flash. Notice how dark the slide is.
