Why the fascination with 10mm?
Ammo is hard to find, ammo that size is going to be heavy, if you DO need to use it, you may be flinching from recoil or noise. Your biggest threat is going to be human, so concealability would be a big plus.
Realistically, a J frame of some flavor is all you need.
So now we get to want.
If you simply WANT a 10mm, well, THAT I completely understand.
But from a utilitarian perspective, a 10mm would be, for me, my last choice.
