This gun started out as a Beretta PX4 in 40 S&W. I sent it to David Olhasso for and action job and a conversion to "G" model (decock only) tthen I sent it to Robar to Stipple the grip and NP3 the slide and internals along with XS big dot sights. This is one of my favorite guns to shoot, it shoots great and Dave Olhasso did an amazing job. Absolutely the best DA/SA trigger I have ever shot.
I went a similar move with my .45 PX4...
I used CCR with their cera-plate. Sent the entire gun in, being I want the metal frame parts done, as well. I put on the Stealth slide release and Bedair guide rod. They will put on the Trijicons and Stealth decocker.
I just bought a Ruger LCP, and I might go a similar route with the plating. I'm unsure on whatever the second pistol will be. If a polymer frame, I will have it plated as well (I'm favoring the Glock, due to the polymer magazines). If I get a metal framed pistol, I will try for a stainless pistol.
