I just bought myself my Christmas present from Brownells: A set of VZ "Gatorback" grip panels for my CCA custom 1911. The double-diamond checkered Ahrend's Cordia wood panels that are on there now are pretty, but less grippy than I'd like. More importantly, both the other guns have the Gatorbacks, and I like them all to feel the same in my hand. Consistency makes me happy.
The Gatorbacks are pretty much bombproof, and the thing I like best about them is that they don't get slippery when my hands get all sweaty on a hot summer day at the range.
