If you want a 458Lott, get the Mod 77 RSM and just be happy. The SS is a bit light for the Lott and you'll have to add quite a bit of weight and get a new thicker recoil pad. In fact, a new thicker recoil pad is mandatory on the 77 also. You just might ask Clark about 577NE brass and where he gets his stuff for his Searcy.
