Some oddities with its frame:
- Ruger stamp?
- No "Made in USA, Marcas Registradas, etc"?
- very strange looking barrel-to-frame interface?
What the heck is it?
Yellow/green is the most visible color to the human eye.
I remember white tennis balls. When they got a little dirty they were hard to see. Then in the 70's they came out with the yellow/green ones. Boy, could I see those a lot better.
I wonder why they chose red that almost disappears as it got dimmer.
