Trailside "Slide Bite" Questions

I got a pair of Nill Grips on my Trailside and I get a little bit of slide bite. I noticed Larry's Guns has a beaver tail that attaches to the gun to help prevent this. Has anyone used this and does it work. How is it attached? I have a pair of the target grips from Hammerli, the plastic ones. They are built to take care of this problem but the Nills are more comfortable in my hand. The Nills weren't built with the extension that sweeps back under the beavertail that is on the gun. Thanks for the help.

I had the same issue, I think I tried the beavertail but my memory is fuzzy on it but I ended up going back to the plastic 2 color target grip which is made different and protects your hand.
