I was looking at ghost ring sights for my Glock 27, made by AmeriGlo, also from Entreprise, anyway has anyone used ghost ring sights on pistols? If so, how did they work for you? I wanted to try something different since my eyes are NOT so great any more and I am having some issues getting a decent sight picture with the meprolites on my Glock. Open to ideas also! Thanks all in advance!
