The trigger stirrup issue is a fairly common problem with mag ejection.........................
I have a dozen 1911's......................Wilson's fit & eject easily from every one of them but I have had Colt mags that would not eject from the Colt pistol that they came with not eject until they were well sanded & polished.
The Colt's are the only mags that have ever given me a problem.
