Watch Gunbroker and ebay for old Krag aftermarket sights. Expect to pay $80 and up. I have a Redfield no-drill that I found on gunbroker several years ago. It does take a longer magazine sideplate screw. Fortunately, mine came with one. It is a very good target sight. Not sure about the Pacific sight. I believe Redfield bought out Pacific many years back, so the installation may well be the same.
