I feel stupid asking BUT, I put a 5.09 long ported 9mm barrel by Stormlake in my G-17 and the gun fires great but will not eject. I`m shooting all bullet weights but mostly 147gr. with semi stout loadings. The brass extracts from the chamber but gets caught by the slide in the port. I feel a new recoil spring is in order but which weight do I need? I know you folks are the experts so here I am. I would appreciate any help.
