Have to agree with those who advise against it, unless it is just a toy. I had a Bond Cowboy Defender in 9mm which I thought might work for SD .. but it weighed a ton, only carried two rounds and had to be cocked against a very heavy spring for each shot, reloading took forever and because of the grip shape, very hard to hold and aim ... finally traded it to my LGS, where it languished in their used case for more than a year ...
I believe Monty Python put it best ... "Run away!!!"
"The gun has been called the great equalizer ... It insures that the people are the equal of their government whenever that government forgets that it is servant and not master of the governed." --Ronald Reagan
