Wow, thanks for all the replies - I didn't think I'd get any. My model 18 is in very good condition. However, I had the an action job and the front of the trigger smoothed. I may have had an orange insert put in the front sight, I honestly can't remember if it came that way or I had it done. I use to have all my revolver work done by Austin Behlert in New Jersey but, again, I can't remember if he did the work on this gun. The double action is as smooth as it gets. Does this change the dynamics at all? I'll try to post a picture.
K22fan, I tried the shooting glasses thing and it just didn't work for me. I guess my eyes are too far gone. I could see the sights great in my right eye but just blur beyond. I could see the target just fine with my left eye but no sights. It was all very confusing and frustrating. Getting old is tough work.
