I don't know. I've seen it and think that if you have to grip your bow for your fingers to fit through it then you aren't holding your bow properly. In other words, you shouldn't be holding your bow anyway. A nice loose grip allows your fingers to very loosely wrap around the front of the riser and keeps the bow from leaving your hand unless you have another problem-- that being the real nice light bow that's easy to carry. I moderately heavy bow is eaier to steady down, aims better, and doesn't jump anywhere when shot
