Bonehead move with my suregrip rebuild.

I've just been out tinkering with it in the garage, after carefully inspecting the case halves for witness marks and fitment, of the 2 positions it can go together, only one feels "natural", where things fit together smoothly free of binding. In this orientation the bolts spin in freely also, where in the other position they feel tighter.

It now has punch marks on the case halves for future reference. That one made me feel as good as locking the keys in the house! You realize instantly after you screw it up!
