I know for sure I got the 250C I think it's the big grip, but I don't know how to tell yet and they didn't know at the store. I'm not having any trouble reaching around the gun, and it seems to feel really good in my hand I don't think I'm going to use any skateboard tape on it. The trigger is, by far the best DAO that I have ever felt. In my opinion, it beats all others, hands down. It also came with factory night sides. The only downside I can tell so far is it only had one magazine. I've been on the Sig website looking to see if they have the other grip frames and assemblies available. I guess I'll call them tomorrow and see when they're going to be available and how much they're going to cost.
