P365 I believe is the smallest 10 shot and Ruger EC9S may be one of the smallest single stacks. Or both use to be. I have one of each, both reliable and accurate. Shield+ is a nice small higher capacity carry gun. Though I had to put talon tape on the grip because it is pretty ruff and I was getting a rash. Lol
The EC9s is also bigger and heavier than the CM9. It's a half inch longer and a full inch taller, yet carries only one more round (which the CM9 can also do with the extended factory mag that is less than an inch longer).
I agree that the Shield Plus is a great higher capacity pistol, but nowhere near smallest.
