I shot both the S and F today, but not the C. The S needs some Sugru and the large insert before it will be perfect for me, but I can still shoot it pretty well. The F with the Sugru and large insert is a big pistol, but it fits me well. The C fits well but is a little bulky for me as a carry gun. I have been very pleasantly surprised by how much I like the S. Glad I can finally put the Kahrs in the safe or sell them. No desire to carry something that small any longer.
