I have a Sig P225 single stack 9mm that I really like. Not exactly small, but about medium size maybe. I also have a Beretta tomcat .32acp it's small. I also have a Walther PPK .380 and a PP .32acp that I would consider not to big. I guess the beretta, and the two Walthers I would consider small, but I still like the Sig 225.
