Hi Robert and welcome. You can do this with no issue. Remember to add a layer of clean fingernail polish to enhance the hardness. When the light holding capability fades, just use fingernail polish remover and rinse and repeat the application. Cheers, stay safe and enjoy!

You Absolutely can! I've done it with our Beretta 950 Jetfire. Sure did help with sight acquisition!!

Good evening to you!! Glow paint will work for awhile if you want permanent night sights I'd just get a set made for the Beretta 92FS. Hope this helps you. Have a good rest of your day.
