Walt, thanks for taking the time to measure and for the pic. I don't consider 4 5/8" to be overly thick or thin,'bout average?
I measured both of my guns for comparison, RBL 16 is 4 7/8", Ithaca/SKB 20 is 4 3/4". Again, this isn't a problem for me. Some with smaller hands would be bothered by it more I would think. This brings out another question. At what point is the grip too small? I would think that this could be much like golf clubs or tennis rackets, very much an individual preference. If you order a gun to your specs is this normally part of the stock dimensions?

My reason for asking this is that I have used the SKB as a test bed over the years as I have gained experience and I hope a little knowledge. The first SxS I owned didn't fit at all which put me on the road to find out why. Read and studied and found out about cast, LOP, pitch etc. I then carved a stock for my second SxS, the SKB. The gun fits well and I have gotten every bit and more out of the gun. At some point soon I would like to have a gun built to my specs. It most likely will be Spanish to fit my budget. I am gathering all the input I can in an effort to get this right, once.

Thanks to all of you and please keep it coming!

Chief
