I have a Springfield 45 1911 trying to fit a Rock Island 9 mm slide. It appears the disconnector has some interference with the 1911 frame. I have it circled in red in the picture attached. The slide is fairly stiff operating on the frame so before I try the dreaded Dremel to remove some material on the frame wanted to ask you 1911 gurus if you have any other suggestion.
thanks
