Thanks for all the wise guidance from this crowd. After lurking for some time, I've picked up a 75 Compact and have new Lok grips and CGW springs on their way. What I'm having trouble finding from any vendor or combination of vendors - is a specific set-up that works well for me on 1911s, Sigs, and Brownings. Specifically, a plain or serrated U-notch rear sight, and a phosphorescent yellow (usually tritium centered) front sight. I find this combination suits my 72 year-old eyes, bringing them right to the big, bold front sight, with no distraction from dots on the rear sight.
Close alternatives are various brands of fiber optic front sights with square notch rear, and phosphorescent/tritium front sights with square notch rear sights - usually with rear tritium vials that stay dark in daylight - so they're not too distracting. Night Fision makes a set like that for CZ 75s, and that will probably be my pick in the absence of other guidance from this experienced group.
So - Has anyone seen this unicorn set-up I'm looking for? Thanks in advance.
