Bill, best of luck getting a gun that makes you happy. We all have 'special' ones that we want for a long time, and when we get one, yahoooo!
I may be wrong here, but I think there was an earlier Taurus 9mm spin-gun that had a frame and cylinder that were only just long enough for the cartridge. Result, small gun. I just didn't have the bucks when I saw one at a gun show several years back, dang-it.
The current ones have the cyclinder long enough for .38 Special, I think. Result, more gun than you need for 9mm.
And the 9mm will not headspace on the rim without the clips. It will headspace on the mouth of the case, just like it does in the auto-loaders. Which means you can shoot them all day that way, if you have a bit of dowel to poke out the cases, for those that don't just pull out with your fingernails.
In my S&W 940 any cases from +P rounds will not easily eject. I need to use a mallet. But in my Ruger 9mm six-gun (the version that uses clips) the +P can be pulled out by the fingernail, usually. I don't know what the Taurus will be like.
