RE: kisser button?
This is actually what a kisser button is for. Your really shouldn't be using a kisser and a peep, they are redundant. You really only need one or the other. There is no question a peep is more accurate than a kisser, unless you have near perfect form. And if that is the case you really wouldn't need the kisser button. I shoot fairly well with out either, but I am much more accurate with a peep, especially at distances farther out than 30 yards.
This is also simular to what the No Peep does, it just does it in a different way. And is a bit more accurate in my opinion.
