I just recently got my pistol back from Mac's. I have mixed feelings about the process. Obviously I like the "no rust for life" guarantee, but I am not 100% satisfied with the appearance of the finish. It appears to have been overapplied to a couple of ares, think of what happens when you spray paint something with too heavy a coat. I am hoping that when this wears down a bit it will look better.
Secondly tell him NOT to do the interior parts if you plan to have any action work done. My gunsmith told me he would never accept another pistol like this one again because of the thick coating he had to get through just to polish the parts that needed it.
And finally, it appeared as though Mac clamped my barrel into a fixture to polish the feedramp and the chamber. Unfortunately, the fixtue left tool marks and a burr on the edge of the feedramp. This has smoothed out a bit with use, but I really don't expect that type of abuse when I send a pistol out for such work.
Although the finish is "rougher" than I expected with the park underneath, the look is growing on me every day. And how could I possibly dislike a Sig with a trigger by Teddy Jacobsen. I like the finished result, but wonder if I would have liked a Robar better . . .
