well ted, apparently, the gun you are referring to is a like new grulla, with the top lever slightly left of center...
the gun locks up tight, as a new gun should...
the position of the top lever left, right or dead center is of no consequence...
this is a bottom bolting gun of the holland & holland design...
should this fine gun ever loosen up to the point of needing tightening, then tighting of the bite of the bottom bolt is a relatively easy fix for an experienced smith to accomplish...
otherwise, if it aint broke, dont fix it...
