Painting the sights on my handgun was a cheap modification that made it much more usable for quick defensive shooting.
Painting the front sight of my handguns for different purposes. White (testors model paint), for hunting in poor light. Flat black for shooting at my flat white painted steel bowling pins. Takes seconds to "change" by just painting over the top of the last color, chipping off when it becomes too thick.
Sometimes you get what you pay for, sometimes you only pay more for what you get.
Three shots are not a "group"...they are a "few".
If the Bible is the literal, infallible, unerring word of God...where are all those witches I am supposed to kill? (Exodus 22:18)
