Thanks for posting the link,
cluttonfred, that was considerate!
I tested the viability of phosphorescent paint on gunsights many years ago ... on a "nightstand gun".
I would place the handgun underneath the nightstand lamp that would be on for at least 30 minutes prior to turning it off and going to sleep.
So long as I did nothing to ruin my night vision (which I found to be difficult), the GITD paint did surprisingly well (admittedly my expectations were low), actually usable for quite a few hours following full "loading".
The fact that the sights looked like crap in the daylight with that stuff on them persuaded me to cancel the project, remove the GITD paint and replace it with something in eye-catching fluorescent on top of a white base.
For
me (other folks' circumstances my differ) ... I found the GITD paint to be of great potential use on a nightstand gun in lining up sights in deep darkness ...
BUT ... except in very rare circumstances, I am not about to shoot any-thing/-one if I cannot see & positively ID my target.
As my sister parrots back to me periodically, "
I own every bullet that I shoot" ... she has certainly learned
that critical concept.
