S. P.,
If you want an A profile barrel in .40 caliber, I suggest you consider a Rice "Southern Classic" barrel. If you prefer some more weight for a more steady hold in target shooting, then you might want to consider a B profile. TVM will use the barrel you send them if you choose to go that route, no need to limit yourself to whatever they offer. Many years ago, I sent them a Douglas barrel and they used it in a SMR i wanted. No problem.
