ditto on the strength of the factory. the first thing my gunsmith does it hand me back the original and tells me to take it home,...he doesn't need it.
He makes his own lugs, with a extruded area on both sides of the rear, which fit into 2 recesses he cuts in the action face, that acts the same as the pins in the badger type. Much thicker, and much heavier in the hand when you compare them to one another.
