After sending a newly purchased 642-1 PC to the factory for a B/C gap correction, I went back to my old reliable 442-1 for EDC. I liked the Altamont Falconia grips on the 642 so much I ordered a pair for the 442. Really like the feel of these boot grips and how they conceal well as they are actually slightly smaller than the S&W stock grips and seem to handle recoil better.
