Jim I saw your posts and the long hex sight you have on the revolver.
I was hoping a few others would have tried them. At $175, I don't want to get something that I won't like.
If you a friend of the inventor, you may want to suggest that he gives away a bunch of them to guys that will review and posts their opinions on the different forums. It might cost him some time and money, but it may get him some traction. $175 is a lot of money to spend on a new idea.
