VASP Rolling Sig Deep
The Virginia State Police, established in 1932, is composed of three bureaus, with over 2,100 sworn troopers and special agents. Since moving out of the revolver game in the 1980s they briefly flirted with S&W 1076s (yup, big ole 10mm Autos) before adopting first the Sig P228 and then the P229 (which they currently carry in spicy .357S).
However, the new kid on the block, starting next year, is the modular P320, which Sig has done all up pretty for them.
