Here is a picture and description of the integral sight from the manual. Any idea if it can be upgraded or if some hi-vis paint/dots can be applied to help?
I don't think that anyone makes anything for that model. Is the problem his eyesight, that he has trouble focusing on the sights? I have trouble my eyes won't focus on handgun sights or anything at arms length. I purchased some bifocal safety glasses that have the magnification in the top of the lens instead of the bottom. In shooting a handgun or my bow I can focus on the sights by just dipping my head down a little and look through the 'reader' portion of the glasses.
I am not exactly sure what the issue is, he just said he was having a hard time seeing/using the sights. Not sure if it's due to his eyesight/glasses or the dark sights. I originally recommended he put some hi-vis paint dots to see if that helps. Will let him know about the bifocal safety glasses and your technique.
Any recommendations on the bifocal safety glasses?
