That's the first I've heard of this ,do you by any chance have a digital to take a pic of so that I might be able to have a better look at your arrow shelf and grip apposed to the way you have your Muzzy mounted ? I have one mounted on my bowTech Dually and I am no where near my hand .
Check your grip ,and are you getting the slap as you release or when your drawing ?
