If you have old eye problem, an assist that works well is the Eyepal, Lyman makes it now (I think it was by somone else before)

Even with a rear peep sight it works better. I shot the 1911 7.5 and got a 5 shot 1.5 inch group at 110 yards a few weeks back.

The 1917 I had not worked up rounds for but I could see the target and sight well enough to shoot out at 110.

I was able to shoot my two iron sight target pistols for the first time in 15 years. Good sight picture and could see the target fine.

Only downside is they don't keep sticking to the glasses with the eletro static cling thing. Not sure why, I just taped on the outer edges onto my eye glasses for ht duration of the shoot.
