Another vote for the nano. I really really really really really wanted the shield, but the nano fit in my hand just as well. AND it was available at a good price.
I've got a Solo. It's finicky on ammo. Doesn't like steel cased ammo. 124gr or heavier. Otherwise, runs good. I also have a New Agent 9mm. It runs like a freight train! Either choice is a little salty, but good choices.
