fellas on a 1873 uberti 44 mag (which I will probably run just at 44-40 power levels), just wondering if there are some sighting options a little easier than standard factory sights? My astigmatisms caught up with me in the right eye and I just dont do well with standard open sights anymore.I dont hunt long ranges but getting onto medium game and targets at 80-90 yards would be nice. Someone suggested a 'marble tang sight' in the store, or a 'williams reciever peep'. Failing that I will find a way to mount a red dot like I did to a 357 rossi, but I am trying not to committ sacrilege just yet. Thanks for any opinions of the sights mentioned above or other suggestions.
