My head is spinning and I’d just like an outside perspective.
You already have a good assortment of solid semiautos in a good caliber (9mm), so maybe now what you should look for is a "fun" handgun. Something you've been curious about but haven't had the opportunity to try out.
Others have suggested k-frame S&W revolvers and that would be a good way to go. They are so well balanced and easy to shoot accurately. Very fine handguns. Love mine.
I'll add that a Colt 1911 might tickle your fancy, too. If you haven't had any trigger time with a 1911 in 45acp, prepare yourself for some fun shooting. There are lots of reasons these old warhorses are still so popular more than 100 years later. A lot of it has to do with how nicely they handle, also. There's some nostalgia among us oldtimers, but I've seen plenty of youngsters wowed by 1911s, too. It would be a nice contrast to the guns you currently have on hand.
