I've got an old Ruger p89 and a Smith and Wesson .357 as far as handguns go. I was at one point eyeballing a Walther P99, but never got around to it.
I keep the Smith in my go-bag with two boxes of ammo and the P89 stays close by in the house.
I'd love to buy more, it's just such an expensive collector hobby when I don't get to shoot nearly as much as I did when I lived out in the boonies.
