I'm considering options for 1377 that I'm adding a steel breech to. I've read that the red/green dot sights don't work well for folks with poor eyesight. I've also read you need to have both eyes open. This is a problem for me since I have a damaged left cornea and leaving my left eye open blurs my vision. I found out a peep sight doesn't work well with one eye closed either. Anyone know how these dot sights work for people like me? I ordered the steel breach with the LPA rear sight so that's a back up. I've also read the LPA sight runs out of vertical adjustment(down) and requires some tinkering to correct it. I've already got a scoped 1377 and was looking for a different optic although I wouldn't rule out another scope.
