I have a double stack Rock Island Arms 1911 hi-cap 9mm. The width of the frame at the mag release is 1.150", obviously wider than all other 1911 frames. I'm looking for an ambidextrous magazine release for it, but I haven't found such an animal. I've called Rock Island and all the companies I can find who make the after market ambi mag releases for 1911's, but no one knows where I can find one that fits my double stack frame. Can anyone help?
