I have a set of slim Elk grips for a full size 1911. Mine developed a crack going from the top bushing hole until about half way down the center. I love the way these grips fit and feel in the hand, so I'd like to repair them. Google has been helpful to a point, but I'm wondering if anyone has any experience in repairing that material, and if so, what did you use/do/ send them off to whom? Thanks in advance, Eric
