A local store has a .22 LCRx on sale, but I always hated those massive adjustable sights they put on the 3" models. Does anyone with more experience with this model see any reason why it wouldn't be that difficult to make a stamped trench insert for the rear sight notch, file off the front sight post, and embed a fiber optic tube into the remainder of the front sight stub? I have a .38 LCR and the aluminum would be easy to file and shape, but I don't know if they did something different with the LCRx, like the front sight base is hollow or something.
