Shooting my 9mm CZ this week with fixed Dawson fiber optic sights and I was hitting better than with my longer barreled .22 M34-1 S&W with the standard sights. That got me to thinking that I should get after market fiber optic sights for the J-frame. Problem being Hi Viz and Dawson don't make adjustable rear fiber optic sights for a J-frame. I've seen white notch outline sight blades or I suppose I could paint on a couple of white dots on the rear sight, but I thought I'd ask it here before I got out my paint set. What have people tried for a better outlined J-frame rear sight? Thanks
