i'm trying to get some ideas. here are some options i am considering:
standard handi sights. (i have takeoffs from a .45-70)
remington sights with firesight inserts (i have takeoffs but they are a bit beat up; i could probably buy a set cheap off fleabay or somewhere else).
skinner peep, and williams or remington ramp front with partridge blade or fire sight.
some other brand of "fire" type sights, like the set on my t/c black diamond; i see those very well.
i much prefer open sights to a scope now that i can see sights very well thanks to my glasses. a handi with open sights is so much more stinking, uh, handy ...
