I've had a few failures to eject using 115 gr. Blazer Brass and American Eagle. I read in another forum the Nano likes 124 gr., which I'll be trying the next time I get to the range. I've also heard it just needs to be "broken in." Not sure why any gun shouldn't be 100% reliable out of the box, or run well with the most common decent ammo. Has anyone else had issues with the Nano?
