I bought one of the original P320 compacts in 357 Sig which has a little longer barrel than the x-compct. I did buy a x-compct grip frame for it, as well as a Wilson Combat carry grip frame. I also have an x-carry in 9mm and have handled the x-compact. The x-compact is a real nice size and if I didn't already have a P365 xl, I'd probably buy one.
