The M&P semi-autos are a great platform choice and I hope your new pistol gives you years of good service. My signature line says it all! I am not a rep for White Dog but they make an outstanding product with a great price and a rapid turnaround time with multiple options. I carry my SR9C in a Purebred, 15 degree forward cant, strong (right) side. I had the sweat shield option added, a necessity in the south, and the holster conceals well, is comfortable to wear, has great retention and draws and reholsters well, too.
Good luck!
