I recently picked up a Springfield Range Officer 1911 .45 pistol and it comes standard with springfileeds adjustable target sights being that it is a competition pistol. I want to switch out the target sights or some fixed night sights because this pistol will primarily be used for home protection. As far as I know, Harrison Design is the only company making rear sights that fit the Range Officer's LPA cut. Note: the LPA cut is different from the "Bomar" cut. Do any of you have or have had the Harrison custom 2 dot rear sights? What do you think? Also do any of you know any other rear night sights that will work with this LPA Cut?
