RZ, this one is a MK II with no cut on the back strap for the stock. The rear sight is an after market adjustable. Yes, I am familiar with the HP. I removed the magazine safety and tore it down for a through cleaning before I slathered with with Eezox. I'll soot it to see how it does and then will get a new recoil spring. I'm thinking hard chrome or Matte Electroless Nickel Plating.
