I agree with not wanting to drill a hole in the riser, but you dont want the one of a kind grip falling off nor your bow bouncing off the driveway with the grip still in your hand. The glue/epoxy may be the way to go but somewhat permanent . Don't want to speak for Ron or Monte ,but I think the grip would have to be hand fitted to the individual riser....again, I think pricey and time consuming but ultra cool....stabilized dyed maple burl grip ,side plate , latch bears.....
