Awesome Gift!
Have a gunsmith hard solder it. It probably will come off with just lock-tite. I also have aging eyes and have several pistols and AK's with big dots. They excel at speed and fast sight picture at close range. The last couple of pistols I bought I mounted a set of Trijicon HD Night Sights. Similar concept, slightly smaller high vis front sight and serrated rear with a u notch. The tritium vials ghost out in the daytime. I think the U shaped notch makes the most difference for me. If you'd like to try them PM me and I'll meet you at the Athens Gun Club range one day.
