I've not used them but hear they do OK. I'm not all that sure of the need fr them on a 380 being the relitave close range needed for accuracy but if you want them by all means have at it.
From the site:Nitesiters are super photo luminescent, and not self luminescent, like Tritium.
That means they need exposure to light before using them. The good news is, 5 minutes of sunlight, close lamp light, or Ultraviolet light is all it takes to provide many hours of luminosity.
