Would someone who has one of these Lipsey special 3-3/4" bbl'd revolvers please measure the notch in their rear sight and advise of notch width. Mine is .088" and I can't see light bars, yet Ruger insists that they only have 2 blades for the rear sight, a square one and one with the v notch. They sent me the v notch and it doesn't satisfy my needs. HELP
(The "Ruger guy" didn't know the dimension of their stock rear sight.)
