I have a 9mm Colt Combat Commander (Series 70) and am considering having it converted to 9x23. 9mm is okay; but, not for 1911--at least according to my tastes. I do have a Series 70 Govt slide so I could just stick with tried and true .45 acp. In any case, I know some of you out there have 9x23 1911s--tell me, then, what all would it take for my 9mm Commander to be set up for 9x23? Thanks.
