Do magazines for 1911 colt work in the amt hardballer?

No, magazines for the Colt 1911 do not work in the AMT Hardballer. While both firearms are based on the 1911 design, the AMT Hardballer has slight differences in magazine dimensions and feeding mechanisms that prevent standard 1911 magazines from functioning reliably in it. It's best to use magazines specifically designed for the Hardballer for optimal performance.
