I have a P290, i like it, havent shot it much yet 200 rounds or so,but its been faultless thus far. Its a little heavier than i think it needs to be, but i can still carry it in a pocket. Have no experiance with the Nano other than holding one, i have seen them for as low as $359 at the gun shows, i might pick one up in the future.
