Sir, as has been noted, twist rate isn't something to worry much about in handguns. Just stick with the "normal" bullet weights for the cartridges in question and you'll be fine.
You can run into problems in rifles when bullets and twist rates are mismatched, but even this is relatively uncommon. It happens most often with ARs and heavy-bullet loads.
Unfortunately, I can't help with jacketed-bullet handgun loads--all my handgun loading is with cast lead bullets.
Hope this helps, and Semper Fi.
