Especially with cast bullets in handguns getting the data with just exactly the components you have is sometimes difficult to impossible. At times we have to rely on our experience and common sense and make judgements from there.
If you need to shorten your OAL by .039" from a listed minimum load then I would lower my powder charge a couple of tenths of a grain then work up. Even if you started at the listed minimum you will be well below a max charge even at the shorter length.
Also keep in mind, published data differs a bit one to another and is merely a guide to the reloader. It is not a Bible.
