My Dan Wesson Specialis is may first ever pistol. I might have gotten into the sports of shooting a little late. At age 50+ my eye sights are not what they use to be. I'm having a hard time with the figure 8 night sights. The dots are too small and is blurry. Will a fiber optic be better? Or is there any other style or brand that you guys can recommend. I intend to replace it with a fully adjustable rear sights. Thanks
