Re Case capacity....I say--It just doesn't matter.
I reload for pistol and rifle and I agree that the internal case capacity of pistol cases is not a major issue.
It's like using match bullets at less than 50 feet. I think it's a waste of money. You can do it if you want to and it won't hurt anything but it won't be a cost effective change for what it gains for you in accuracy.
I have some .45's loaded on a mixed bag of cases right now and that doesn't bother me. Where you see a big difference is in rifle rounds for long range shooting. Some manuals even caution you to watch carefully for pressure signs when charging commercial versus military brass due to differences in internal case capacity.
I wasn't real clear. Thanks for pointing that out. I placed an edit in my initial post.
