Hello all! I just bought a nano 9mm and love it! My question is when i went to the range yesterday and shot 5 rounds through it cause the company i bought it from let me test fire it before i bought it but only gave me 5 rounds. When I was shooting I had thought i shot all five rounds so i dropped the magazine and realized i had only shot 4. There was one round left so i shot it without the magazine in it. The round did fire correctly but the shell casing did not eject and fell through the bottom of the gun. Does anyone know why that happened? could it be that the magazine was not in? After that happened I shot another 50 round through it with no issues every round ejected. Any comments would be very appreciated..Thanx!!
