Ordered one ... http://www.wyomingsightdrifter.com/index.html
Am totally impressed with the drifter instead of a piece of flannel -brass punch and hammer:
Was in the safes today moving long arms around and pulled out a Stevens 44. Front sight was not centered so 1st use of the new sight drifter. With a V center gauge - a few snaps both ways with new sight drifter - dead nuts centered with no marks on the sight and so fast to center front sights
Totally Impressed with the Product - so much so I called Steve, the maker, and told him so
