That's weird...I just looked up "sear" (and scear as well for that matter) in the online Webster's dictionary, and no mention of anything having to do with the part in a gun lock. I guess everyone that has been calling that part by that name for the past several hundred years has been wrong, eh Wonko?

In all seriousness, all this goes to show is that even the most comprehensive dictionaries are nothing more than an abridged listing of words in a given language.
