Years ago, L C Smith had a safety that worked whether pulled or pushed. The problem was you could never be sure when it was on safe. I worked with a fellow that lost part of his hand by lifting his LC by the muzzle. He shouldn't have done that but thirteen year olds sometimes make poor decisions.
I prefer to push safties forward or down, and pull hammers back, but I'm and old dog that doesn't enjoy learning new tricks.
