I used to have a 4" blued model with the wood insert (Lett) grips.
I sold it off like a dummie, and regretted it so much that I got a 3-inch stainless model. The second one was a "rescue" from a local gun shop's used gun counter.
Those Talos are awesome-looking guns, but a bit outside of my normal budget.
For grips, I ordered the compact grips (that used to be stock on the 3" models) and "grip locator" from Midway USA. I then ordered the cocobolo inserts from an eBay seller named "1Chig" who does outstanding work. As soon as Midway gets more of the compact grips in stock, I will get a set for my second GP100. Right now, it is wearing the Uncle Mike's combat grips that you see in the picture. They are actually pretty decent, but I want the other style.
