Product mislabeled by trijicon. - Trijicon RMR Pistol Mount

It is my belief that Trijicon has mislabeled a large amount of 1911 RMR mounts as RM48, which purported fit the Springfield XD and XDm. The item I received could not have possibly fit a Springfield firearm and matched the schematic I found online for a Trijicon 1911 mount. This matches a similar complaint I found on another website which starts with the letter A. Only purchase this item if you can see it in person and verify that it will fit the rear slide cut for the Springfield XD/XDm line.
