Awesome!I 100% endorse Bunker Arms. I would also suggest Joe Chambers! I think both are not only amazing smiths, but know how to Blue a gun to perfection.
If you are specifically asking about Brandan's Blue Only. I can confidently say you have nothing to worry about! I've seen many people blue pistols... 90% of the people trash the gun. Including many people who are considered "good". I'm not going to name any companies or Smiths by name but, something's that get passed off as acceptable is mind blowing to me. Rolled letters, rounder edges, just bad stuff.
I'll also say, Bunker does make his own Salts. I have a 1911 he build me, his blueing has more of a gray tone to it... more like older carbona blue. A lot of it has to do with the actual metal but, his blue seems a little different.
The pic I am including isn't his "master blue" but an example of the color. Additionally, the other pistol (mirror) was polished by him... but has DLC as the finish.
Beautiful finish. Are the grips made of Koa wood?Mark at Texas patriot arms has this one, I helped take a few pics when he got it. Beautiful, prob the nicest master bluing I've ever hand my hands on. No way to capture it in pics
