You already have a full size Storm, the Nano is a pocket/subcompact geared toward the CCW market, but would make a handy vehicle pistol as well. But since you live in an authoritarian state that desires to leave the law abiding citizenry vulnerable outside the home, the need for the Nano is questionable for HD and range use. A year old 92FS in good condition is a very good deal for $350-$400 and is an absolutely wonderful HD and range pistol. If it were me and I could not conceal carry I'd go with the true and tried classic warhorse myself. Me personally I'd prefer more bb's than what the Nano offers but to each their own, but I think you're limited to 10 rounds anyway. If bedlam broke out I'd indeed feel well prepared w/ the storm and the 92. I own both. But, if you just want a different and much, much, smaller platform the Nano would be a great option and/or if you moved from the Socialist state to freedom it would make a great CCW. The choice is yours, but 2 very different platforms to consider especially being you already own a full size. I for one would never and I mean never live in California due to that state's anti self defense and anti gun laws.
