I have a 1911G which I love very much, probably my most accurate 1911.
But I don't know what the dovetail is cut for.
Probably your best bet is to send an email to Kahr customer service and hopefully they will give us the straight skinny.
I went through the same dilemma with my Dan Wesson CBob, I wrote it down but forget now what that dovetail is cut for too.
Never did change the sights.

Dietrich: For a fat girl you sure don't sweat much.
Cue sound of Head slap.
