Just picked up the new a17 and took it out to the range today. However, almost every time I fire, the magazine releases and falls on the ground and another round wont chamber. I also noticed that it was denting the next casing that it would try to chamber. I'm using the Hornady ammo. I know they recommend the CCI, but all they had was the Hornady and they claimed other ammo should work fine. Any idea what's wrong? Someone told me they thought it may just be the magazine. It's a 10 round rotary mag. The place I bought it from has a return policy, thinking I may just take it back and let somebody else be the guinea pig.
