I voted for the Bersa because of it's reliability, even though I find it a bit large to be called a mouse gun.
Nevertheless, it will eat most any ammo you care to feed it, and it's not overly hard on springs. Easy on recoil, too.
I also own the P3AT, which I carry a lot of the time, simply because it disappears in a pocket. Somewhere around 10 or 11 ounces fully loaded, I believe.
I've fired a friends Rohrbaugh and while I liked it, it will roll your wrist back.
It's also as heavy as my S&W 638 loaded with gold dots. The 638 goes in my pocket a lot of the time, too.
The Seecamp .32 is a pussycat, but it's a bit heavy.
