Where can I buy good sights for my bull. I am open to fixed or target type that are not all black. The stock sights that come on these guns have got to be the worst on the market. Are any of the fiber optic sights on some of other Taurus revolvers compatable? Only as a last resort would I consider paint or nail polish. I was considering a Burris fastfire but would still like to know if anyone on here knows of my original question. All input or intel will be greatly appreciated.
